Harvest Tips
Kaai lychees ripen from May to July depending on location and weather. Harvest clusters when fully red and slightly firm by cutting with sharp pruning shears rather than pulling. The fruit should not detach easily from the branch when ripe—this indicates readiness. Harvest in the early morning to minimize moisture loss. Refrigerate at 40-45°F for up to 2-4 weeks or freeze for longer storage.
