Herbaceous Grafting, as its name indicates, is applicable for increasing plants when still growing, but, at the same time, becoming solidified and passing into an herbaceous state. The system has been applied with success in Grafting the Melon on the Cucumber, the Tomato on the Potato, dwarf species of cacti on tall ones, &c. Its chief advantage, however, is in the increase of resinous trees, principally Pines, by inserting grafts on the points of commoner species, which may be used as stocks. The proper time for the operation is in May, when the young shoots are just beginning to grow, or else when growth stops and the shoots begin changing to a woody nature. Stock and scion should be, if possible, similar in texture. The former must be cut off just below the terminal buds, and nearly all the leaves removed from the point thus obtained. This should be carefully split, and the scion prepared wedge-shaped, and inserted rather deeply, allowing the barks to coincide, as in all other methods. Tie in with worsted, cover the cuts with grafting wax, and shade them from sunshine by paper caps until growth is resumed. The Walnut may be successfully propagated by terminal Herbaceous Grafting, employing shoots for both scion and stock that have not become woody. These trees may also be terminal-grafted in spring, just before growth commences.
