Planting and Spacing:

When planting starfruit seedlings or saplings, it's crucial to ensure sufficient spacing between them. A distance of 15 to 20 feet (4.5 to 6 meters) between trees is recommended to allow for optimal growth and canopy development.

Watering and Fertilization:

Starfruit trees need regular watering, particularly during the dry season or periods of prolonged drought. The soil should be kept consistently moist but not waterlogged. Fertilizing is essential for maintaining the tree's health and promoting fruit production. A balanced fertilizer, rich in nitrogen, phosphorus, and potassium, can be applied every 2 to 3 months.

Pruning:

Starfruit trees benefit from regular pruning, which helps to maintain their shape, encourage new growth, and improve fruit production. Pruning should be done during the dormant season, typically in winter or early spring.
