[Cultivation]
Propagate from cuttings.
It prefers sunny, well-drained, fertile soil.
If sunlight is poor, the branches become sparse and the color of the new shoots is poor.
For established plants, rainfall is sufficient unless sunny weather continues in summer and the soil becomes severely dry.
Apply organic fertilizer in winter.
Prune in early summer, when the color of the new shoots has settled, and in September; however, flower buds form in summer, so if pruned in September, the plant will not flower the following year.
Pests and diseases include powdery mildew, brown spot, sesame-colored leaf spot, anthracnose, and borers (larvae of longhorn beetles).
