Soil Type

Water: Longan, native to humid subtropics, thrives in moist environments and is drought-tolerant while preferring consistent humidity. Water bi-weekly to maintain soil moisture without saturation. Mulching enriches outdoor growth by retaining moisture and protecting roots during weather changes.

Fertilize: Fertilization is vital for longan's growth, particularly in fruiting. Use a balanced fertilizer rich in potassium and phosphorus every 3-4 weeks during growth, and every two months in dormancy. Apply 1 lb of fertilizer per trunk inch for mature trees. Always water after application.

Pruning: Longan is a tropical fruit tree recognized for its sweet, translucent fruit. Prune in early to late spring by removing dead or crowded branches to improve airflow and fruit quality. Clean, angled cuts support healing, maintaining the tree's size, shape, and productivity.

Propagation: Longan is a tropical fruit tree thriving in warm, subtropical climates. It produces small aromatic fruits. Propagation through seed sowing in well-draining soil is essential. Consistent moisture and protection from extremities during the seedling phase promote robust growth.
