Maintaining longan trees involves:

1. Climate: Plant in tropical or subtropical climates with warm temperatures.
2. Soil: Provide well-draining soil, and ensure it’s rich in organic matter.
3. Watering: Keep the soil consistently moist, especially during dry periods. However, avoid waterlogged conditions.
4. Fertilization: Feed the tree with a balanced fertilizer during the growing season. Adjust based on the tree’s age and size.
5. Pruning: Regularly prune to shape the tree and remove dead or crowded branches.
6. Pest Control: Monitor for pests like aphids and scale insects. Treat promptly if infestations occur.
7. Harvesting: Harvest longans when the fruit skin turns brown and cracks, indicating ripeness.

By addressing these aspects, you’ll support the health and productivity of your longan tree, ensuring a bountiful harvest of sweet and delicious fruits.
