Finger limes thrive in warm climates, ideally USDA Zones 9-11, with temperatures ranging from 40°F to 100°F. If you live in colder regions, you can grow them in pots and bring them indoors during winter. - Sunlight

Prune the tree after harvest to maintain size and remove dead branches. Be cautious of the tree’s sharp thorns when pruning. Regular pruning helps promote better airflow and fruit production. - Pest Management
