The temperature requirement is not high, and it can withstand the low temperature of-10℃. (2) moisture. Fear of waterlogging, avoid planting in low wetlands; It thrives in a warm and humid climate. (3) Soil and fertilization. It grows vigorously in fertile, loose, slightly acidic or acidic soil.

Apply fertilizer at the end of July and the beginning of September to make the flowers bloom brightly. (4) pruning in winter. In situ plants should be cut from the trunk of annual branches. First, cut off all sprouting branches, diseased branches and overlapping branches in the potted plant, and cut the upper part of the complete terminal buds of other branches at 1 cm, leaving about 5 cm. Pruning after flowering: Prune the residual flowers after flowering in summer to prevent them from bearing seeds, reduce nutrient loss and promote the germination and flowering of new branches. (5) reproduction. Multipurpose cutting method. Old branches were cut in February, and branches with vigorous growth and length of 15 cm were selected as cuttings and inserted in sandy loam. Softwood cuttings should be disinfected with 0.3% potassium permanganate solution in the middle and late June with yellow sandy soil as matrix. The semi-lignified branches of that year were put into clear water for cutting. Generally, seedlings can be transplanted after 6 ~ 10 days, 15 days and 1 month. (6) pest control. After the disease is found, it can be controlled with Bordeaux solution or carbendazim 600 times solution.
