The Gardeners' Chronicle. September 23, 1899. p. 250.

HAS any reader of the Gardeners' Chronicle ever tried Maréchal Niel worked on Rose Devoniensis as a panacea for canker and loss of vigour after a few years cultivation under glass? If not, a market grower would recommend a trial being made, as with me the Rose has never yet shown a tendency to canker, but rather, as years go on, increase in vigour. There is much to recommend the use of Devoniensis as a stock, it being vigorous, with thick bark, and tenacious of life; the flowers, though good, are not so valuable as those of M. Niel, and it is not so profuse or regular a bloomer indoors. I have tried M. Niel on almost every kind of Rose, Manetti, de la Grifferae, Sweet Briar (which is a good one), Dog-Roses of the hedge-rows, and the less prickly one which grows in damp ground; Dundee Rambler, Hybrid Perpetual, Lamarque, Rêve d'Or, Cellini Forestier, and Gloire de Dijon, with interesting results; but the old Tea-Rose Devoniensis takes the palm for producing the weightiest blooms. I do not mean from Devoniensis on its own roots, but when worked on the seedling Briar or prepared Briar-stocks, which when established make robust growths, 10 to 12 feet long. From stocks from cuttings, excepting in the case of Gloire de Dijon, they do not reach that degree of vigour quickly, but the union with the Briar gives it forthwith.

The method of procedure is by budding and inarching; by the former, inserting, the bud in the robust growths, which this variety produces liberally, from 3 to 6 inches apart, awaiting results. A man could quickly insert a few hundred, and no matter if the buds are from weak wood, on this stock the shoots develop very weighty blooms. Of course, the branches operated upon must be kept in an upward, or at least, an oblique position, or the buds will start into growth directly, as many have so done to a length of 4 to 6 feet since May. The whole of the stems can be done at one time (even now it is not too late—I put on ninety buds on September 9), or a few at a time, as the growth develops. If it is desired to have several varieties on a plant, choose Catherine Mermet, Madame Thérèse Levet, Lambard, Perle, &c., which will be attractive the whole summer. A branch treated in this manner trained horizontally, has given many fine blooms, M. Niel having grown very freely, and the branch is now about 17 feet long, and I am still adding other buds alternately with M. Niel.

Those that start are shortened back, so as to carry from six to ten flowers, never all of them being wished for. If the shoot be bent to a horizontal position, each bud will start. After flowering, prune hard back to the main stem if a M. Niel, and other growth will follow for another year, a method generally followed with this variety. If the sap is not on the move, the application of a few pots of water to the roots will soon set up activity. If the worked buds remain dormant till the spring, the blooms are of the finest quality. I could say more about inarching M. Niel on Devoniensis, Gloire de Dijon, Rêve d'Or, A. K. Richardson, and others, at some future time. [Please do so. ED.] M. Niel worked on A. K. Richardson, bloomed freely a second time this year.

Perhaps "Growler" will ask "why all this trouble when Roses can be bought so cheaply?" Canker comes to M. Niel in many kinds of soil, and if we cannot cure it, we may try to prevent it by using a stock which is not liable to it.
