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. Although it is tender plants, in the main, which are propagated by cuttings of growing wood, the above methods can be practiced advantageously with some hardy plants. The wood, which is invariably more successful if hard- ened, is obtained either from plants forced for this purpose, e. g., spi- rea, Deutzia graciliSf etc., or it is gathered in June and July out of doors, e. g., lilac, hy- drangea, etc. Cuttings of growing wood should be potted in 2- or 3-inch pots, in a rather sandy soil, when the roots are from H-^i inches long. It is sometimes good economy to box them, i. e., plant them a few inches apart in flats, when not immediately re- quired. (2) Long Cuttings of Mipened Wood in Open Air.— This method is used to propagate many hardy trees and shrubs, e. g., willows, currants, grapes, forsythia, etc. Wood of the current year's growth is gathered in au- tumn or early winter, before severe frost, and either stored in a cool cellar, covering with moss or fresh earth to prevent drying, or immediately made into cuttings. These (see Fig. 626) should be made 6 inches or more long and should contain at least 2 buds. It is not neces- 622. Propagating-box. The excrescences, knots or knaurs, which are found on the trunks and the main limbs of olive trees, are some- times used as cuttings for propagation. (3) Short cuttings of ripened wood (Fig. 627) are used under glass with tender or half-hardy species, with new introduc- tions, in cases where the grower is short of stock, and when the plant is delicate and small. The wood should be gathered before severe frost and the cuttings made and planted directly in October and November. Make them from 2-4 inches long (sometimes a single eye onl
