[Cultivation]
Propagate from seed, cuttings, or layering.
For seed, collect ripe fruit, wash off the pulp thoroughly, and then sow.
It prefers partial shade and fertile, well-drained soil that is moderately moist.
For potted plants, water thoroughly when the soil surface dries; for plants in the ground, rainfall is sufficient unless summer brings a long spell of sunny weather and the soil becomes dry.
Apply fertilizer in winter, and also apply a slow-release chemical fertilizer with equal amounts of the three components after flowering as a thank-you fertilizer.
No pruning is done and the natural shape is enjoyed.
There are no particular pests or diseases.
