Lychee Care
Lychee is a subtropical tree that prefers warm winters, full sun, good drainage, and protection from wind. In Northeast Florida it should be considered a marginal tropical fruit requiring careful site selection and freeze protection.
Site & Cold Protection
- Sun: Plant in full sun for best flowering and fruit production.
- Spacing: Allow generous space from buildings, large trees, and power lines; lychee can become a large tree if not pruned.
- Drainage: Do not plant where water stands after normal summer rains.
- Cold: Young trees and new growth are cold-sensitive. Choose a warm microclimate and protect during freezes.
Watering & Establishment
- New trees: Keep the root ball evenly moist during establishment, especially in sandy soil.
- Established trees: Avoid prolonged drought during flowering and fruit development, but do not keep roots saturated.
- Mulch: Mulch the root zone to conserve moisture while keeping mulch away from the trunk.
- Wind: Wind protection helps prevent leaf burn, branch breakage, and flower/fruit loss.
Fertilization & Pruning
- Young trees: Use light, frequent nutrition while trees are establishing; avoid forcing excessive soft growth before cold weather.
- Mature trees: Avoid excessive nitrogen, which can encourage vegetative growth at the expense of flowering.
- Pruning: After harvest, selectively reduce long shoots and maintain manageable height. Avoid severe routine pruning.
- Micronutrients: Monitor for iron and other micronutrient deficiencies, particularly in alkaline soils.
Flowering & Fruit
- Bloom: Cool, relatively dry winter conditions help induce flowering; unusually warm winters can reduce bloom.
- Pollination: Lychee flowers are insect-pollinated; protect pollinators and avoid unnecessary insecticide use during bloom.
- Harvest: Harvest clusters when fruit has reached full cultivar color and flavor; lychee does not continue to improve substantially after picking.
