Citron trees require consistent moisture, especially during flowering and fruiting periods. Water deeply when the top few centimeters of soil feel dry, ensuring good drainage to prevent root rot.

Reduce watering slightly in cooler months, but never allow the soil to dry out completely. Young trees need more frequent watering than established ones.

Prune citron trees to maintain shape, remove dead or diseased branches, and encourage air circulation and fruit production.

The best time for major pruning is after harvest or in late winter/early spring before new growth begins. Light shaping and removal of suckers can be done throughout the year.

Avoid heavy pruning that removes too much foliage at once.

Citron can be propagated by seed, cuttings, or grafting. Seeds should be fresh and planted in well-draining soil, though they may not produce true-to-type plants.

Semi-hardwood cuttings taken in summer can be rooted with the aid of rooting hormone. Grafting is a common method to ensure desired fruit quality and disease resistance, often onto a suitable rootstock.

Repot young citron trees annually or biennially into a slightly larger container with fresh, well-draining citrus potting mix. For mature trees in containers, repot every 2-3 years or refresh the top layer of soil.

Repotting is best done in spring before new growth starts, carefully disturbing the roots as little as possible to minimize stress.
