Japanese Lime Plant Care

Japanese Lime (Tilia japonica) belongs to the Malvaceae family within the Tilia genus. Japanese Lime is native to eastern China and Japan, preferring to grow in mountains up to 2000 m. Japanese Lime is also known as Japanese Linden.

Japanese Lime displays a tall, deciduous tree growth habit, reaching up to 80 ft tall with a spread of approximately 40 ft. Japanese Lime produces fragrant pale yellow flowers in drooping clusters.

Leaf size: approximately 5 inches.

Water a young or newly planted Japanese Lime every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Japanese Lime thrives in full sun to partial shade.

Tilia japonica tolerates temperatures of 50–100°F. Japanese Lime prefers humidity levels of 40–70%.

Well-draining loamy soil with good fertility. Good drainage is essential for Japanese Lime to prevent waterlogging, which leads to root rot and fungal issues.

Feed Japanese Lime every 8 months 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining loamy soil with good fertility. Avoid low spots where water collects after rain.

Japanese Lime is suited to USDA Zone 5a – 8b.

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.

Japanese Lime can spread to about 40 ft (12.2 m) and reach about 80 ft (24 m) tall. Space plants about 40 ft (12.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Japanese Lime 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.

Japanese Lime is hardy down to USDA zone 5a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Japanese Lime can be propagated through seeds, hardwood cuttings. Similar propagation techniques also apply to amur linden plant care, which shares the same genus.

Japanese Lime is susceptible to aphids, japanese beetles, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Japanese Lime grows outdoors in USDA Zone 5a – 8b. It survives winters down to planting zone 5a. Japanese Lime is native to eastern China and Japan, preferring to grow in mountains up to 2000 m.
