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. 1254 PECAN PECAN common orchard trees were rarely successful, and the opinion became prevalent that this species could not be hudded or g:rafted. Various devices for pi'opagatiug by layers, by upturned roots and root-cuttings were suggested and tested at different times, but none of these proved of permanent value. The first really successful work in graft-propagation seems to have been by crown-grafting on Pecan stocks. This is most commonly practiced in early spring on stocks in place, having a crown diameter of from 1 inch to 2 or 3 inches. The stock should be cut oft' smoothly at the crown and grafted either by splice, or side-cleft graft, according to size of stock. Cions with terminal iiiids are preferable, and they should in all cases be so cut that but one scarf exposes the pith. In this method no wax is used, but the grafted stump is carefully mounded up with moist earth to the top bud of the cion, to prevent drying out. In the humid and mild climate of the Gulf states, this is probably the most promising method for the inexperienced amateur. Bench-splice root-grafting on 6-inch top sections of one-year-old seed- lings has been fairly successful in some cases, but grafts set on lower sections of root are not considered worthy of planting out. Annular budding on the new wood of second-year seedlings yields a considerable proportion of success when favorable climatic condi- tions prevail, but in unfavorable seasons, as of extreme drought or heavy rainfall, it results in almost total fail- ure even with expert operators. Top-working of the Pecan is generally difficult, only a small percentage of success usually being obtained. 1695. Outlines, showing variation in the Pecan (X^)
