Care tips
It prefers full sun to partial shade, with at least 4-6 hours of direct sunlight per day for optimal flowering and fruiting. Watering should be moderate, allowing the top layer of the substrate to dry out between waterings, but without letting the plant completely dehydrate. Use a well-draining substrate rich in organic matter. A common mistake is overwatering, which can lead to root rot.
