Buds of many varieties of C. japonica, when treated in late summer (about Aug. 20 to Sept. 15), will bloom before cold weather sets in. It takes from 4 to 10 weeks, depending on variety , for buds to respond. Such blooms are often of exceptional quality. Some of the formal doubles and early blooming types, that are not generally satisfactory in this area, respond very well. The growth bud adjacent to the flower bud which is to be treated is removed and a drop of 1% water solution of gibberellic acid is applied at the point where the growth bud has been removed.
