The Book of Roses

This is perhaps, for the amateur, the most convenient and certain method. The best season for layering is the summer, from the end of June to the end of August; and, for some varieties, even later. The rose which is to be multiplied should be in a condition of vigorous growth.

Loosen and pulverize the soil around it; and, if heavy and adhesive, add a liberal quantity of very old manure mixed with its bulk of sharp sand. The implements needed for the operation are a knife, a trowel, and hooked wooden pegs. Choose a well-ripened shoot of the same season's growth, and strip off the leaves from its base a foot or more up the stalk; but, by all means, suffer the leaves at the end to remain. Bend the shoot gently downward with the left hand, and insert the edge of the knife in its upper or inner side six or eight inches from its base, and immediately below a bud. Cut half way through the stem; then turn the edge of the knife upward, and cautiously slit the stem through the middle, to the length of an inch and a half, thus a tongue of wood, with a bud at its end, will be formed. With the thumb and finger of the left hand raise the upper part of the stem erect, at the same time by a slight twist turning the tongue aside, steadying the stem meanwhile with the right hand. Thus the tongue will be brought to a right angle, or nearly so, with the part of the stem from which it was cut. Hold it in this position with the left hand, while with the trowel you make a slit in the soil just beneath it. Into this insert the tongue and bent part of the stem to a depth not much exceeding two inches. Press the earth firmly round them, and pin them down with one of the hooked pegs. Some operators cut the tongue on the lower or outer side of the stem; but this has a double disadvantage. In the first place, the stem is much more liable to break in being bent; and, in the next place, the tongue is liable to re-unite with the cut part, and thus defeat the operation. When all is finished, the extremity of the shoot should stand out of the ground as nearly upright as possible, and should by no means be cut back,—a mistaken practice in use with some gardeners.

In a favorable season, most of the layers will be well rooted before the frost sets in. If the weather is very dry, there will be many failures. Instead of roots, a hard cellular substance will form in a ball around the tongue. In the dry summer of 1864, the rose-layers were thus "clubbed" with lumps often as large as a hen's egg; but cases like this are rare.

In November, it is better in our severe climate to take up the rooted layers, and keep them during winter in a "cold frame;" that is, a frame constructed like that of a hot-bed, without the heat. Here they should be set closely in light soil to the depth of at least six inches, and covered with boards and matting; or they may be potted in small pots, and placed in a frame or cellar.

Layers may be made in spring from wood of the last season's growth; but laying the young wood during slimmer, as described above, is much to be preferred.

All roses may be propagated by cuttings; but some kinds strike root much more readily than others. The hard-wooded roses, including the entire family of the Hardy June roses, and especially the Mosses, are increased with difficulty by cuttings. The Hybrid Perpétuais root more readily; while the tender ever-blooming roses, including the Teas, Noisettes, and Chinas, are propagated in this way with great ease.

Cuttings may be made from the ripened or the half-ripened wood. In the case of roses, and of nearly all ligneous plants, cuttings made from the ripe wood do not require bottom-heat, and are more likely to be injured than benefited by it. On the other hand, cuttings of the soft or unripe wood strike root with more quickness and certainty if stimulated by the application of a gentle heat from below.
