What Soil Mix Works Best for a Lemon Tree?

Well-draining soil mix. Good drainage is essential for Lemon Tree to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Lemon Tree?

Feed Lemon Tree every month during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Where Should You Plant a Lemon Tree?

Choose a spot with full sun and well-draining soil mix. Avoid low spots where water collects after rain.

Lemon Tree is suited to USDA Zone 9a – 11b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

How Far Apart Should You Plant a Lemon Tree?

Lemon Tree can spread to about 10 ft (3 m) and reach about 15 ft (5 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Lemon Tree?

Prune Lemon Tree while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Lemon Tree is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.
