Alexander Montgomery, Jr. THE HISTORY AND CULTURE OF GRAFTED ROSES FOR FORCING. The Author's Purpose, The subject of grafted roses as ap- plied to the American system of forcing, while now quite well understood in all its various aspects by most of the large and many smaller rose growers of the country, still remains with some an open question. It is not my intention to use this opportunity accorded me to put . forth an argument in favor of having all rose growers use grafted stock, but to state, so far as is known, some of the facts in connection with the first at- tempts to improve the conditions under which forcing roses are grown, and to give a comprehensive description of ev- erything connected with the successful handling of grafted roses. If my readers will bear with me to the end of my story I think they will agree with me that this question of grafted versus own-root roses is one which no one man can decide for all, but which each individual must work out for himself, according to the character of his soil, the varieties he is growing, and the " system of production which is best adapted to his requirements. While the subject has been pretty thoroughly covered from time to time by various competent writers, it is thought that it may prove of interest, at least to the novice in the art of grafting, to cover the whole story from the time some of the first stocks were introduced down to the present day. The only way a grower can decide whether grafted roses can be grown by him is by having a thorough under- standing of the subject. Therefore the treatment of the stocks, the operation of grafting, the handling of the grafting case, and the subsequent treatment of the plants, will all be given with con- siderable detail. This, perhaps, while seeming entirely unnecessary to those who are already experts, will it is hoped prove of interest to some who may not yel have had any experience in this line. I trust that I shall make myself so clear that the veriest novice in the art will obtain a clear idea of the prac- tice, and perhaps even some who are not strangers to the operatibn, but who have not been as successful as they could wish, will be helped in their work. It is not the intention to tell merely the proper but also the improper meth- ods, and this latter knowledge is, after all, that which often does us the most good. Early Trials. In 1883 Mr. Montgomery sent to a large firm of nurserymen in Eng- ■ land an order for 1,000 of the new rose, Catherine Mermet, all to be budded on the seedling brier. This de- mand, however, proved to be a stagger- er for even a big firm, and after having scoured the country they were able to deliver only 500 plants. While no definite facts are available in regard to the experiments with budded roses, it is believed that this was the fir^st large importation of tea roses for forc- ing, not on their own roots. As the importer of these plants had had an extensive experience in Britain with roses budded on the brier, he hoped that by adapting this stock to the ORAFTED ROSES FOR FORCINH. American system of forcing he could perhaps obtain the same satisfactory results that had followed its use on the other side, but in this he was destined to be disappointed. The Brier Stock. These plants did very well up to the fitst of November, better in fact than own root up to that time, but from November to April they were as sound asleep as it is possible for a rose to be. No amount of coaxing known in the art of forcing could get those stocks to give the slightest sign that they ever had any intention of growing during the short days of the winter months. From April on into the summer, however, they produced some good blooms, but by that time the growth on the whole was much inferior to the own-root plants which had been flowering all winter. Numerous experiments have been made since on different varieties but with practically the same results. From a forcing standpoint, then, this stock had proved a failure, but never- theless it must be admitted that for size, form and absolute perfection of finish of the individual bloom, the brier under certain conditions is the stock to vise. As showing the high esteem in which it is held in Britain I quote the following from "A Book About Boses," by Dean Hole: I know that the Manetti will grow luxuriantly where the brier will not grow at all; that In a toward season it will produce some varieties of the rose In their most perfect forin. those "especially which have the smoother wood, • * • ■but I am nevertheless convinced that by far the greater number of the ' most perfect rosea may be, are, and will be grown and shown from our Indigenous British brier, taken from hedgerows, struck from cuttings, or raised from seed. From this, then, coupled with our- own experience it is easily seen that because a stock may be good for one purpose it is not necessarily good for all. Success \C^ith Manetti. After this experience with budded briers, Catherine Marmet grafted on the Manetti was obtained from a prominent Scotch firm. Grafted plants were called for on account of the difficulty that had been experienced in getting budded stock. The newly budded teas were of- ten winter-killed in the ground and con- sequently, in order to produce plants in quantity, the nurseryman had to resort to winter grafting. Eesults from this experiment were so satisfactory that during the next few years all varieties were imported in in- creasing numbers until, in 1886, the ex- pense of these large grafted plants be- gan to be quite an item, and so it was decided to import stocks and to try all the methods of grafting which it was thought might be adapted to the new system. ' The American Process of Grafting. The old idea used to be to coat the union of the graft and scion with a smearing of grafting wax and to run the plants at a somewhat lower temper- ature than is now considered proper. This, however, was a very tedious pro- cess and in the mind of the American grower it was altogether too slow, con- sidering the fact that he had to produce during the three winter months all of the plants which he intended to set out for the coming season. Then, by ex- perimenting, it was found that by rais- ing the temperature and increasing the moisture the waxing process could be omitted entirely and a more satisfac- tory union could be produced in less time and with less labor. After these encouraging results with Catherine Mermet and other varieties all the leading roses of that period were tried on the Manetti. Niphetos, Bon Silene, William Francis Bennett, Lady Mary Fitzwilliam and many others of lesser note, showed a marked improve- ment over own-root plants. The Fatnous Cornelia Cook. One of the most interesting sights for visitors to our place during the latter part of the '80s were the great banks of that grand old favorite, Cor- nelia Cook. The term "banks" is used advisedly, for banks they really were, the style of growing being en- tirely different from anything now in vogue. The plants, which were all in A Bundle of Manetti Stocks as Received from Europe. GRAFTED ROSES FOR FORCISG. solid beds, were at that time forced as long as seven or eight years. Where the beds were wide enough, about seven feet, the plants were placed in rows three feet apart across the bed. An iron trellis in the shape of an inverted "V" was built in between each two rows and the plants tied down to this, leaving one row facing east and the other west. As the plants were grown so long in the same bed they made fine canes and these, when thoroughly ripened off during the summer, produced magnificent blooms the following sea- son. I remember one house in particu- lar 300 feet long, with a single row of plants lengthwise of the back bed and tied back to a trellis, leaving the whole bank facing the south. This indeed, when in the midst of a full crop, was a truly wonderful sight. Now, _ one of the causes which un- doubtedly contributed to these results and which, by the way, was not made known for some time, was the fact that all these fine plants were grafted on the Manetti stock. Finally, however, when Charles Anderson, of the John Henderson Company, a great admirer of this method of forcing, was let into the secret, he immediately set about graft- ing his own Cooks and was so elated with his success that he was unable to hold on to his secret. Stock for Marechal Niel. It was in a somewhat similar way to this that that finest of all yellow roses, Marechal Niel, was treated. This vari- ety had failed to thrive on the Manetti and, while it gave very satisfactory results on the Banksia, still it seemed in time to outgrow this, being in fact a more rapid grower than the stock it- self. Mr. Montgomery having read of Dean Hole's very high opinion of Glorie de Diion as a stock for Marechal Niel, decided to give it a trial under glass at Waban Conservatories. A house 35x100 feet, twenty feet to the ridge, containing sixty plants on this stock, was laid out with one large bed arid the plants trained on upright trellises across the house. These plants in time made canes enough to completely fill the house, and bore in one crop from 25,000' to 30,000 blooms, the product being shipped as far as Washington on the~ south, Montreal on the north and Chi- cago on the west. No better stock than Glorie de Dijon has ever been found for Marechal Niel, either for out-of- doors or for indoor forcing. The Varioas Stocks. In comparing the desirability of the different stocks which could be made available, we have,used the common dog rose or brier (Kosa canina), Eosa multi- ilora Japonica and De la GriflEerae, Bosa Banksia and Manetti. In regard to re- sults, there is such a vast superiority in the use of the Manetti that comparisons are of value only as a matter of inter- esting history. The brier, the most popular stock used in the British Isles for the production of exhibition blooms, has already been mentioned. Faalts of Multiflora. Multiflora has never proved satisfac- tory, never in fact being equal on the whole to own-root plants. While it is undoubtedly a vigorous grower, it does not seem to have the property of being able to transmit this quality to its Scion and, moreover, we have never been able to produce a bloom from a multiflora graft that was equal in coloi; to one from an own-root plant. But be- yond all these objections, it seems to be extremely susceptible to the club- root caused by eel worms or nematodes, and this fact alone ought to make its use objectionable, for most rose growers of even limited experience know that it is only too easy to get club-root on own-root plants, without going to the trouble of grafting to get it. Experience With De la Grifferae. De la Grifferae has been tried with a number of varieties. It is a vigorous stock and makes a perfect union, the findSt, in fact, of any stock which we have ever tried, but still it produces a very inferior plant. Thinking perhaps that it might prove the thing for the yellow class — as, by the way, the Man- TypicaJ Examples of the English Manetti Stock. GRAFTED ROSES FOR FORCING. etti has been a failure with roses of the Perle des Jardins type — we gave it a trial, using the variety Sunrise, planted in a solid bed. For the first four months they absolutely refused to move, merely keeping alive; then suddenly they began to pick up and show signs of increased activity. Suspecting what might be the cause of this new lease of ~ life which the plants had taken, several of them were dug up and, sure enough, our judgment was correct: they had be- gun to send out own-roots from the callus at the union of stock and scion, wliile the stocks themselves had made practically no roots since the day they were put in. Banksia for the Yellow Class. The Banksia rose ought theoretically to be the ideal stock, as it is practically evergreen. This surely ought to suit our friends Who rave about the Man- etti not being the proper stock to use because it is not evergreen. However, it is not evergreen stocks we are look- ing for, but evergreen roses, on "any old" stock, so long as we get the blooms. But the Banksia has proved valuable in ouu experience only in the case of the yellow class. As before mentioned, the Marechal Niel did fairly well on it. Again, as far back as 1889, . the Waban Conservatories had a very fine house of Perle des Jardins on this stock and about that time Mr. Peter Boll, of Maiden, had remarkable suc- cess with this rose on the Banksia. As our market does not take kindly to the yellow sorts, we have not done any- thing further in the way of experiment- ing with this stock, but if anyone who is growing some of the Perle class is not satisfied with it on its own roots, I would advise him strongly to try the Banksia rose as a stock for grafting. Manetti the Successful Stock. Finally we come to the Manetti and we can truly say that up to date this has proved itself to be the thing for nearly all roses grown under glass. That it has not proved itself better than the own roots with 'every variety we must all admit, and also even that in some exceptional localities it has proven a failure, but I think it will be found that where this is so the reason lies in the soil. It is generally con- ceded that the Manetti rose thrives in light to medium coarse gravelly loam, and is not seen at its very best in an exceptionally heavy, fine-grained, sticky or tenacious soil. The Manetti is a comparatively shallow fibrous-rooting rose. It has a voracious appetite and will in most cases stand considerably more feeding than roses on their own roots. But, more than all this, the Manetti seems to be absolutely free from the attack of eel worms. This point alone ought to make it very valuable to those who are troubled with this pest, because roses grafted on the Manetti are prac- tically insured against an attack of club-root. We do not know why this is so, and of course could not state positively that under certain conditions it would remain free from the dreaded nematodes, but we do know that up to the present time it has done so. An objection which has been made against the use of roses grafted on the Manetti is the fact that any check during the late fall is liable to put the plants to sleep for the winter, but we all know that own-root roses are sub- ject to the same defect if given half a chance. So, as it is the growers' busi- ness to see that they do not get a check, it does seem as though such a lame excuse as this ought not to fright- en the wide-awake rosarian. A point in favor of using the Man- etti is found in the case of roses which are difficult to propagate on their own roots. Very often growers who have failed almost completely to propagate a rose have succeeded readily in graft- ing it on the Manetti. As a specific example, I recall seeing growers who could find no advantage in grafting American Beauty other than the fact that, having failed to get up a stock of plants on their own roots, they had succeeded in securing a fine lot on the Manetti. GKAFTED ROSES FOR FORCING. 15 Present Day Varieties. "We are growing Mrs. J. P. Morgan and Mrs. Oliver Ames on the Manetti, and have had some plants of Morgan in a solid bed as long as nine years with no apparent deterioration in the quality of _ the flowers, i although after the fourth "or fifth year there was a de- crease in the quantity. There has been some complaint of these varieties not doing well on this stock, a large percentage dying off, sometimes even when the plants are in their second year. "While we have had some experience with this trouble, it has never bothered us to an alarming extent nnd we consider that the graft- ed plants are enough better to more than compensate for any slight loss. The cause of the defect seems to be that Morgan unites rather poorly with the stock and any poorly grafted plant, whether of Morgan or any other vari- ety, is liable to canker at the union. The remedy would seem to be to use special care in grafting and to have the stock and scion very nearly the same size, so that the union will be prac- tically perfect. We have tried Morgan on both De la GrifEerae and the Bank- sia, but with unsatisfactory results. Golden Gate, Ivory, Kaiserin Augus- ta Victoria and Souvenir du President Carnot are all grafted, but the differ- ence between them and owuiroot plants is not so marked as with some other varieties. Still the many advantages possessed by grafts, rapidity of growth, freedom from elub-root, and general adaptability to our soil, are worth more than the extra cost of grafting. Liberty is so much better with us grafted that there is really no com- parison. Yet, on the other hand, I have seen localities where the exact reverse was true; but this merely bears out the statement previously made that in deciding the question of grafted ver- sus own-root plants each grower must be a law unto himself. American Beauty is grown on its own roots. "We have experimented with grafted plants and at -the present time have a bed of Beauties on the Manetti, but as we have not yet seen any decid- ed advantage in favor of either, and as this variety is such a vigorous grow- er on its own roots, we have not seen fit to declare our preference for grafts. There is one advantage, however, that the grafts have which may prove of considerable value. In starting up own-root plants after they have been dried off they are frequently subject to an attack of yellows, American Beauty being especially susceptible. Grafted Brides and Maids are very much less likely to be troubled with the yellows when grafted, and it will in all prob- ability be found that, by putting Beau- ties on the Manetti, they can be grown successfully two or three years in the same soil with very little risk. Bride and Bridesmaid are all grafted, and indeed since 1897 there has not been an own-root plant of these on our place. Quality and Quantity. It is unnecessary to go over again the advantages secured by grafting, but it may be well to make a few re- marks on the quality and quantity of product. In regard to quality it can be said that with most varieties ihere will be a general improvement in all grades of the cut, and particularly in the me- ,dium and smaller grades. This is espe- ■ cially noticeable in the increased stiff- ness of the stems, while with some Tiinds there will be darker foliage and better-colored blooms. "With Brides and Maids the highest quality is reached during .the second year and rarely continues after the fourth. As to quantity, figures are often mis- Iteading because numbers depend to such an extent on the method of dis- budding; but, taking for example the system followed by growers who cater to the very critical markets of our larger cities, a house of own-root Brides or Maids that would average fifty flow- ers to the plant would be exceptional, but a house of grafted plants with an average of fifty would be only a good house and an exceptional one would go as high as seventy-five. These propor- tional figures will hold good up to the GRAFTED ROSES FOR FORCING. end of the third year, although the actual average per plant will generally fall off somewhat after the second year. It seems to be the general opinion, among those who have never grown grafted stock, that the superiority over own-root is chiefly during the early autumn months. In order to dispel any such notion, I shall give the figures of the cut by months from a house of own- root roses, and also from the same house when planted with grafts. This is not a special case but only one of many which could be quoted to support our contention in favor of the Manetti. While these figures do not, of course, take into consideration the quality of the flowers, still, assuming that the grades are at least equal, and I believe it is generally admitted that they are, they present evidence which ought to satisfy the most skeptical.

It shows the same bench space to have produced practic- ally forty per cent more flowers on graft- ed than on own-root plants, an increase calculated to command the considera- tion of even the most successful grow- ers of own-root stock; and it shows the increase to be well distributed through the season, the month of December, for instance, showing an increased cut of nearly fifty per cent as compared with the house ' of own-root plants. Coltaral Methods. Presuming that I may have Inspired in some at least a desire to make a trial of grafted roses, I will take up the details of making the grafts and the subsequent handling of the plants. The frocess of making the grafts will be given in considerable detail, as it is the basis for success, the after care of the grafted and own- root plants differing in but few par- ticulars. To begin at the beginning: Procuring the Stocks. As the best stocks at present come from Britain, I should advise giving an order to some reliable nurseryman. This should be done during the summer preceding the fall when the stocks are to be delivered. 'I' lie next thing to do is to keep posted on the exact date of the shipment and arrival of the same, and if one cannot be around per- sonally to see that they are rushed through the custom house, this import- ant work should be intrusted to a brok- er in whom one may have confidence, with instructions to see that the ship- ment is delivered as quickly as possible after arrival. I have no doubt but that many thousands of stocks have been ruined beyond recovery by being left lying carelessly around warehouses in boxes with covers off, exposed to drying winds, thus allowing them to shrivel up long before they reach the grower. In the cases of small growers living in the same section, it would" seem to be advisable to^club together and have their separ^pifeders sent as one large shipmeni^^his would un- doubtedly cheapen tne cost of shipment as well as facilitate the delivery of the goods. It must not be understood, however, that early lifted stocks, as a rule, are rec- ommended, for nothing will give the grower more trouble than a lot of green Manetti that have been shipped before they were thoroughly ripened. They will almost certainly shrivel up and no amount of care that is bestowed on them will be able to prevent this. Generally speaking, it will be after the middle of December before first-class Manetti can reach this country from Britain. Heel in at Once. On the arrival of the stocks, if they have been properly packed, the bun- dles will be slightly moist and the stocks should appear fresh and plump. Now right here is the very place where a < J3 ■XI I a M o 18 J GRAFTED ROSES FOR FORUIKG. many beginners have made great fail- ures, and straightway blamed their dealers for sending poor stuff. There may be, and undoubtedly are, many ex- cellent ways of handling Manetti at this particular stage, but the one I mention has given very satisfactory results and beginners would do well to follow it. All packing or covering should be removed from the bundles and the stocks immediately plunged in trenches in soil to two-thirds of their depth and given a thorough watering, taking care to wash the soil well in about the roots. It is not necessary to plunge the stocks separately; they will do just as well in bundles, if all cover- ing is' taken off. PotHng Up. In from four or five days to a week they will be ready for potting, but if they are kept cool, and about 40 degrees is right, there need be no hurry about the matter as they ought to keep in this condition for at least a month; and if two or three batches are potted each week they will come along in about the right quantity for grafting. If the stocks are allowed to remain in the trenches until they have just started to make white rootlets they will generally take root more quickly when potted. Two and one-half inch pots are the proper size to use and, indeed, if the stocks are properly rooted this size will be found quite small enough, for it must be remembered we expect to have a good-sized plant on the stock before it is ready for a shift to a 3%- inch pot. ■ Pot good and firm, firmer than you would rooted cuttings; water thoroughly and place in a house with a temperature of 45 degrees at night to 50 degrees in the day. Do not water again until you are absolutely certain they need it, or, I might better say, so long as the soil remains moist they will require no water at the roots. Dampen the stems of the stocks three or four times a day, according to the weather, using a fine spray so' that the pots may not become soaked. The Grafting Case. Now, while waiting for the Manetti to root, it is time to get a grafting case ready and, although this need not be an elaborate affair, there are a few things that are very necessary. The case must be ti'ght; this is the first and, I consider, the most important item. It ought to have bottom heat so that an even temperature of 75 degrees can be maintained day and night. We have had experience with all tempera- tures from 90 degrees down to 75 de- grees and have come to the conclusion that 7o degrees is right. The grafting case should have a fair amount of light. A rose house is a good place for a case during January and February grafting, but it must be shaded from the strong sun during the middle of the day, with some thin material that will not shut out all the light; newspapers are very satisfactory for a man who doesn't wish to waste money. A north propagating housecan be used with good results duSag March, when rose houses are becoming too hot for the best work. In regard to size, this is not so im- portant. We have done good work with a case seven feet wide, two feet high in the middle, even span, one sash on each side, hinged at the top; also in a small case thr^B*^et wide, one sash, eighteen inches high at the back and twelve inches at the front. These I should say would" be the extremes in size. Anything between would serve the purpose very well, but my prefer- ence would be for six inches to a foot of head room over the stocks when grafted. Of course there are many notions and frills which may be added to suit the fancy of the builder, but I shall re- peat the necessary points: First, have the case tight, not pretty tight nor anything but very tight. Second, have bottom heat and, third, have direct light. Put in two or three inches of coal ashes or sand, pound firmly and wet thoroughly, for this, it must be re- membered, is where the necessary mois- ture IS coming from for the first few GRAFTED ROSES FOR FORCING. days. If all instructions have been carried out everything should now be ready for the operation of grafting. Appliances for Grafting. The appliances necessary for this are few and very simple. In the first place A Whip Graft. (Stock and scion about equal size.) there should be seats for the operators to sit on, low enough so that the feet may be placed firmly on the ground and the knees brought up to within a comfortable working distance from the body. In front of the sitters ought to be a bench a foot or so higher than the seats, on which may be placed the scions and stocks. Flats to carry the stocks are very convenient if made to hold just an even thirty-two 2% -inch pots. Eaffia, which is the best material for tying, should be slightly damp and cut in bunches to the proper length. A good sharp knife — shoe knives which can be bought for 15 cents are first- class for this work — and a layer of wet sphagnum moss on the bench, to lay the cut scions on, complete the equip- ment. Size and Stage. The stocks should be chosen as near the size of the scions as possible and, although a stock larger than the scion is not objectionable, the reverse would be very much so. The proper stage to use a stock is when it has started to root in the pots and positively never before. It is gen- erally safe to graft when the buds just begin to start, as this is usually a sign, if the plants have not been kept too warm, that root action has started. Speaking broadly, then, the time limit should be not before the buds start and not after the shoots have grown to half an inch. I do not by any means want to insinuate that the operation cannot be performed at other stages, but it can be done best within the limits laid down. The scion ought to be good firm wood with a plump bud, but at any rate not started over a quarter of an inch. Where the shoot is over this length it will generally rot off in the ease and so make it necessary for the scion to form new eyes, whieli it will sometimes do, but more often "it causes the scion to rot also. The leaves should be trimmed somewhat closer than for cuttings, as this lessens the opportunity for damping off. As for the number of eyes to leave, one is all that is necessary, but if the wood is close-jointed two are not objectionable and, indeed, some prefer this latter as Small and Large Scion.on Same Size Stock. (Whip graft with large Bolon and modlfted whip graft with small sclou.) GRAFTED ROSES FOR FORCING. it gives a chance to get one eye under ground when planting. v' The Kind of Union. Now in regard to the kind of union to make, there are only two that are worthy of much consideration. One is generally known as the whip, and the other I shall designate for the pur- pose of description as a modified form of whip grafting. The first is formed by making an oblique cut from ono-half to three-quarters of an inch in length, according to the size of the stock, and cutting the scion to match the same, placing the cut surfaces together and securing firmly with raffia. The points to "make sure of are that at least one side and the bottom cut of the scion are so placed that the cambium cells, the layer of cells between the bark and the wood, are in perfect contact with the corresponding cells in the stock; that in no case must the pith either in the stock or in the scion be left ex- posed, because while ex;posed wood cells will, callus over, the pith will not. Making the Graft. It is a good plan to have two knives, one for stocks and one for scions, and to cut a batch of scions before starting to graft; they will keep for some time if kept sprinkled on sphagnum. If the benches have been built as de- scribed, a person sitting on the lower one and facing the table will be in the proper position for quick work. Place the pot containing the stock between the knees, steady with the loft hand, make a clean, oblique upward cut and hold facing up; without laying down the knife pick out a suitable size scion and hold it on Ihe stock with the forefinger and thumb of the left hand, always matching at least the bottom and side toward the operator. Grasp a piece of rafiia which has been cut previously to the proper length; insert one end between the forefinger and sec- ond finger. Wind carefully and firmly beginning always at the top and not winding too closely together, as close windini gives a chance for moisture to collect beneath the raffia and causes rot- ting of the scion. The neatest way to make the tie is to pass the free end through beneath the last twist of the raffia and draw tight. The plants should not be allowed to stand around too long, as the green scion will, shrivel up. There are, of course, many ways that grafting can be done, but if the be- ginner will carry out carefully the de- tails mentioned, with the assurance that he is on the right track, he will rapidly become expert and conclude that, after all, there was considerably more talk about it than there was work. The Test of Watchfniness, Now if anj'one thinks that after he has performed all of the foregoing in- structions his labors are over he surely is making a great mistake, for although everything up to this stage must be done with care, the real test of his watchful- ness comes after the grafts are placed in the case. For the first four or five days after the plants are put in the case, if the bottom, whether it be ashes or sand, has been properly moistened it will not be necessary to open the case. But this rule will not always hold good, because the novice will be perhaps very likely to have either too much or too little moisture. If too wet the leaves will become saturated with moisture and both leaves and stems will begin to bjacken and rot. This latter condition is generally a sure sign that the temper- ature is too high or else the case is too wet; this, however, would not hold good for weak or soft scions, because they would be likely to rot with even the best treatment. The only thing to do, then, if the ease is too wet is to raise the sash very slightly; the thickness of a lath is plenty, eyen if the plants have been in only two days. This will give a chance for the air to circulate and will likely carry out the surplus moisture. Watch results carefully and if any leaves show the least sign of drooping, close the case at once.

On the other hand, if the case is too dry the remedy is obvious; damp very slightly with a fine mist. Mist is what is meant as it describes exactly what is wanted; and 'keep the case tight. Ailing the Plants. After five or six days, then, provided everything has gone right, the caUus should be far enough advanced to al- low of admitting air. This should be done, to start with, not over fifteen to twenty minutes morning and afternoon, and gradually increased each succeed- ing day until the sash can be kept up all day. It is advisable to close the case for the first night or so after a full day of airing; then for three or four nights following leave on some air, about half that of the daytime, until finally, in from fifteen to twenty days, the plants will be able to stand full air day and night; and in from twenty to thirty days they should be hard enough to take out, but even then they will require shading from the strong sun for a few days. It is taken for granted that even the novice will know that he must keep the. pots properly watered, neither too wet nor too dry, rather dry than wet, for obvious reasons; but it will be well perhaps to tell him that, from the time the plants begin to take air for the full day, they ought to be damped over- head twice a day with a very fine spray, until they are removed from the case and have become thoroughly hardened. Of course, neither minutes nor days can be an exact guide, but are mentioned only in order to give an approximate idea of the time usually required. The best guides, and in fact the only ones a person will probably depend on after he has had some practice are hia eyes To sum up in a nutshell, the most common causes of failure in the graft- ing ease are: First, shriveling due to too dry an atmosphere, either through improper airing or a poorly built struc- ture, allowing air to get in through the cracks; and, second, damping or rotting off, due to not enough ventila- tion, or else too moist an atmosphere. Grafting Case for Few Plants. While on the subject of cases I may mention a method that has proven very satisfactory for a limited number of plants, such as seedlings or a new vari- ety, when the wood is scarce and needs special care. Take a box of convenient size, a cracker box is good, putty up all the cracks, put an inch of well mois- tened sphagnunj moss in the bottom, and place the case on the sand in a propagating bed; set in the grafts, lay on a light of glass, making tight with putty, and let alone. After about ten days handle the same as a regular case. With careful grafting 100 vper cent can be taken out with this method. Grafting Dormant Wood. There is also a scheme that can be used for dorma,nt wood which does not require a grafting case. It cannot be recommended for general use, but only in special cases, such, for instance, as when a grower has parted with a five- dollar bill for some "highly recom- mended" French novelty and feels that he possibly might get his money's worth if only he could graft the few little dor- mant eyes. To proceed, then, select good plump stocks direct from the bundles, picking out those which have not started from the eyes. Take scions that are well ripened and dormant. The operation of making the union is the same as for regular grafting except that after tying it should be well covered . with grafting wax, which should be melted in a water bath so that it may not be hot -enough to injure the wood. After waxing they should be packed i^ boxes in upright layers, with sphagnum moss between, and placed in a house with a temperature of 45 degrees. In from four to six weeks, or at the time when the stocks begin to send out white rootlets, they may be taken out and potted, when they should be treat- ed the same as though they were newly potted stocks alone, except that as the 21 GRAFTED KOSES FOR FORCING. Rose House in Which Solid Beds and Tile Drainage are Employed. roots begin to take hold of the soil the temperature should he gradually in- creased. After the bud in the scion has started to grow the temperature should reach normal. This plan has worked well for graft- ing dormant hybrid perpetuals and, also, it can be used quite successfully with dormant Kaiserin and Carnot. Beds or Benches ? Having now a good batch of choice young stock, the question arises, are beds or benches preferable? For plants that are to be forced two or three years in the same soil I should say most de- cidedly use beds, for a variety of rea- sons. The Manetti, being a gross feed- er, requires plenty of room in which to search for food. With our own rather light soil we plant in from seven to eight inches; but this matter' of the proper depth of soil is, of course, an entirely local one and depends upon the texture of loam which is' available for the work, a heavy, fine-grained clay necessitating a lesser depth in order to allow air and water to pass through it readily. A Good Bed. A very serviceable and economical bed is built as follows: Drive 3x3-ineh chestnut posts four feet apart along the line of the outer edges of the bed; the width of the bed will, of course, vary according to the notions of the grower. Spike onto the posts, on each side of the bed, two lines of plank 8x 1% inches, leaving the bottom plank raised two inches from the ground. Fill in about six inches of stones or broken rocks, placing carefully so as to allow for free circulation of air. Over this I § Hi a ^ o 26 GRAFTED ROSES FOR FORCING. put three or four inches of coarse gravel, dump in the soil and the bed is ready for planting. In localities where gravel or stone is not plentiful, drain tile can probably be secured quite rea- sonably and ought to answer the pur- pose equally as well as stones and gravel. Of course, if a man thinks that his grandchildren two generations hence will be satisfied with any form of bed which happens to be the fashion of the present day, he may construct any of the elaborate forms, using cement or brick, or any of the patented what- nots; but the one described will be used generally by the grower whose capital for the: increase of his glass area must be taken from the profits of his business. Trend Toward Solid Beds. The trend at the present time seems - to be toward so-called solid beds, as nearly all the large ranges, at least in the east, which have been constructed recently are equipped with solid beds; One of the most striking instances of this reversion from raised benches to solid beds is found in the cases of those Beauty growers who a few years ago set out young plants on benches, and who are now growing their Beauties in beds as long as three, and in some cases four, years without replanting. While, as a rule, they do not claim any great increase in the yearly average of qual- ity, they do get a longer cutting season, in addition to the saving in young plants, soil and cost of planting. One of the chief objections to grow- ing plants more than one year on benches is the difficulty of properly dry- ing them off on account of the danger of the soil becoming too dry and kill- ing the roots completely. The solid bed, it may be remarked in this con- nection, maintains a more even condi- tion of moisture and temperature, both summer and winter, than a bench, and consequently lessens the chances of in- jury' to the plants from neglect or in- competence on the part of the work- man. While plants on a bench can be car- ried over successfully by the experi- enced grower, the beginner will find that his chances of failure are consider- , ably lessened if he makes his first at- tempt in solid beds. Union Most Be Btiried. The subsequent treatment of the grafted plants does not differ radically from that of own-root roses except in a few particulars. The one thing which is absolutely necessary, and which must be done to secure the best results with grafted roses, is to plant them so that the whole of the union of graft and scion will always be from one-half to one inch below the surface of the soil. This is imperative, not only that the plants may make roots from the union, ,but also fo r other reasons which do not seem to be so eaailv eypla ineri; be- cause, aside from this question of roots, it seems to be a fact that the Manetti union needs to be surrounded with that condition of air and moisture which is found best in soil. Moreover, the cells that form the callus at the union have a tendency to dry up when exposed to the sun and air, and consequently are not able to perform properly their funotiona of transmitting the sap from stock to scion. For this reason, also, I believe that young grafted plants which have been allowed to become pot-bound and thoroughly hardened, have received a check from which they will never fully recover. I shall repeat, then, if conditions are such that the grafted plants cannot be given full justice by placing the union below the soil, then by all means do not attempt to grow them, but use own- root plants in preference. Carrying the Plants Over. There is one other point, also, on which it may be well to say a few words, and that is the method used in handling stock which it is intended to grow more than one year. The gen- eral practice is to force the plants up to the end of June, then gradually dry off the beds, at the same time giving J o § 28 GRAFTED ROSES FOE FORCING. all the air possible day and night, thus allowing root^ .and wood to become well ripened, although, in the case of teas the plants, should not actually become dormant; they will start stronger if not alloiwed to become too hard, but are merely rested — rested describes the condition best of anything. If ever the wood of teas begins to get yellow and -the leaves fall off, it is a sure sign of the soil being too dry and no time should be lost in correct- ing this, as this condition of too dry soil is the principal cause of failure to ripen our rose bushes successfully. ' The exact point . at which to give water or to withhold it altogether is very diffi- cult to state in just so many words, but, as I have said, if the wood in ripening up has not lost its dark- green color and the leaves have not fallen off, then the plants may be con- sidered generally, to be in good condi- tion, and an occasional syringing or light watering should be sufficient. In from four to six weeks from the time the plants began to rest they will be ready to start, into growth, but be- fore starting they most likely will need some pruning. This I shall divide into two classes, taking Brides and Maids as an example of light pruning, and Liberty as a specimen of the class re- quiring close pruning. Light Pruning. For the first kinds it is recommended that only the tops of the plants be cut off, generally the last growth that has been made being sufficient, if it has been properly ripened. Only the very lightest wood or useless brush should be cut out completely, and, in fact, unless the plants are good and strong it would be safest for a beginner to cut nothing but the tops, and then, after the plants have made a good healthy start, he may do a little thinning out. I must put special stress on this mat- tei- of cutting out, as it is the very point on which there may be a great variety of opinions as to what consti- tutes useless wood. It is certainly true that unless ajperson knows what he is about he will do the least damage and have the greatest chance of success by letting the plants alone, with the excep- tion of merely cutting off the tops. While it is the common practice to leave Brides and Maids standing up- right after pruning, there are occasions when it is almost imperative to bend them down. This is especially so ia the ease of plants over two years old, which often become so tall that, in order to get them within a convenient working distance, they would have to be cut back too hard; consequently the only alternative is to bend them down and tie out in fan shape, taking care not to cross the canes any more than necessary. Close Pruning. The second class, of which Liberty has been cited as an example, requires close pruninlg. Kaiserin and Carnot also are familiar examples. They should be cut back somewhat similar to hybrid perpetuals. The general rule is to cut one-year-old plants to four or five good eyes, and the second and fol- lowing years Ijack on the first growth made after starting up the plants dur- ing that year. Of course, they will grow all right if not cut back to the limit, but the longest stems usually come from the closest cut plants, allow- ance being made for the different varie- ties, as a strong growing sort will, not require as close pruning as a weak kind. Most of the present-day varieties, then, can be placed under these two classes, but I have no doubt that many of the roses of the future will require treatment which will be midway be- tween these two extremes. Starting Into Growth. The method of starting the plants into growth is about the same in all cases. The beds should be thoroughly cleaned off and given a good watering. Some prefer to remove a little of the old soil, but it is not at all necessary atid I doubt very much if there is enough gain to pay for the trouble, except, perhaps, in special cases. After the beds have had a g6dd watering, whatever manures or fertiliz- 6EAFTED ROSES FOE FORCING. 29 era one is accustomed to use may be put on and thoroughly watered in. Now, this is the important part; it may take one watering and it may take three or four, but at any rate do it thoroughly. Then let the soil alone. This, also, is important, as no more water is required until the plants break into a good red, healthy growth. Examine the soil and when little white rootlets are found, it is a sign that the plants will take more water if carefully applied, but do not give too much, as an overdose at this stage will cause the young shoots to turn yellow. This is the danger point, but once over this stage, the plants will be ready for the regular treatment which is given to any rose. From Benches to Beds. Some growers prefer to grow their plants on benches for the first year and replant into solid beds the second year. This gives very satisfactory re- sults and can be recommended to any who wish to run plants for two or three years but do not care to stfri in with solid beds. The treatment is about the same as though- carried over without changing the soil. The plants should be ripened sufficiently so that they may be lifted without danger of the wood shriveling. When ready to transfer to the new soil they should be watered enough so that they may be lifted with a good ball of soil on the roots. Now, while they may be planted directly into the new soil, the better way, and by long odds the safest, is to put them outdoors in the sun, throw in a little soil between the plants and water well. In four or five days the roots will begin to start, when they should be brought in and planted. Tramp the soil in firmly about the roots, leaving a basin around each plant, so that only the soil con- taining roots will be wet, and water thoroughly. The only danger points now are dry air and wet soil. The first causes the wood to shrivel; to prevent this, keep the walks damp and the bushes sprayed fbr a few days, with a very fine spray. The second causes the new growth to start yellow, or even, in some cases, the plants to die outright. The remedy depends mostly on the skill and expe- rience of the grower, but in general I may say that the first watering often proves sufficient to start the roots; at any rate, the less water they receive until the plants have begun to grow well, the less will be the chances of failure.
