Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 620. Permanent propagating frames in a greenhouse of moistened paper. The average length of these cut- tings is from 1 to 3 inches, but they can be made longer or shorter; much depends upon the nature of the plant. The best growers prefer short cuttings; the advantage of a long piece to begin with is more than offset by greater danger of wilting and consequent retrogression. It is not necessary to cut to a bud, i. e., at the node, in the more easily handled plants except in some her- baceous tuberous-rooted plants, like dahlia (see Fig. G25), and Sah'ia patens, in which a crown must be formed to insure future growth. Make the cut where it will give the proper length. A part of the leaves should be removed, always enougn to secure a clean stem for planting, and as many more as are needed to prevent disastrous wilt- ing: this factor varies greatly. In a hardwood cutting of lemon verbena all leaves are taken off, iu zonale geraniums from the open ground few if any are left, in coleus and verbena about one half are removed, while in Otea fragrans, Daphne odora, heath, etc., only enough for planting. Use a sharp knife; but scissors are handy for trimming and sometimes for making cuttings of those small wooded ijlauts which root easily. The cuttings of plants with milky juice should be washed before planting. Some- times the lower ends are allowed to dry for several hours, the tops being protected against wilting. Large and succulent cut- tings, e. g., of pineapple, cotyledon, cac- tus, etc., should be dried before planting by letting them lie on the surface of the propagating bed for several days, or they may be planted in dry sand at first. Under these conditions a callus forms which ten
