Requirements to Grow Star Fruit plant


Star Fruit plants thrive in full sun exposure, receiving at least 6-8 hours of direct sunlight daily. Ensure Star Fruit Plant is placed in a location with ample sunlight for optimal growth and fruit production.


Star Fruit plants prefer well-draining soil that is rich in organic matter. A loamy soil mixture with good moisture retention is ideal.

Avoid waterlogged or heavy clay soils, as they can lead to root rot. Maintain soil pH between 5.5 and 6.5 for optimal growth.


Star Fruit plants require regular watering to keep the soil consistently moist. However, they are sensitive to overwatering. Water the plant deeply, allowing the top inch of soil to dry out between waterings.

During the hot and dry months, increase the frequency of watering to prevent dehydration.


Star Fruit plants thrive in warm tropical and subtropical climates. They grow best in temperatures ranging between 25°C to 35°C.

These plants are commonly found in regions with high humidity and temperatures that do not dip below 10°C.
