About the fruit: The longan peel is a dull brown and has sweet, earthy, textured pulp surrounding a single seed. The fruit is eaten fresh, as well as and canned.

Be aware: The blooms are sometimes attacked by the lychee webworm.

Pruning: The longan can be difficult to prune as it tends to have a large amount of upright growth. Remove strong verticals and encourage lateral growth.

Planting: Make sure not to plant too deep. Dig the hole bigger than the container but refill the hole with the native soil so the plant’s first flare root is at or just above ground level. Protect the tree from mechanical damage (string trimmers and mowers).

Fertilizer: Use a low nitrogen fertilizer two to three times during the rainy season (May to October). Drench with chelated iron (EDDHA) and use a micro-element foliar spray two to three times from May to October.
