Citrus × AurantiifoliaCitrus × aurantiifolia

Key limes prefer consistently moist soil but dislike waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly in winter when growth slows.

Ensure good drainage to prevent root rot, especially in containers. Overwatering is a common cause of problems.

Prune Key limes to shape the tree, remove dead or crossing branches, and improve air circulation. Light pruning can be done anytime, but heavier pruning is best in late winter or early spring before new growth begins.

Remove suckers arising from below the graft union. Aim for an open, vase-like structure.

Key limes are typically propagated by grafting or budding onto rootstock. Seed propagation is possible but may not produce true-to-type fruit and trees can take many years to mature.

Cuttings can also be rooted, but grafting often results in more vigorous and productive plants.

Repot young Key lime trees every 1-2 years, or when they become root-bound. Mature trees can be repotted less frequently, every 3-5 years. Use a well-draining potting mix, ideally formulated for citrus.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
