Japanese White Birch

Betula platyphylla

The Story

Plant Bio

Betula platyphylla, the Japanese white birch, is a graceful deciduous tree from Manchuria, Korea and Japan, reaching thirty to forty feet high and fifteen to twenty-five across. The bark is chalky white and peels in thin sheets, and the triangular leaves turn clear yellow in autumn. Catkins hang from the bare branches in March and April.

It is a cool-climate tree that grows poorly and dies young in hot, humid summers, where heat-stressed trees are quickly finished off by bronze birch borer. South of its comfortable range, plant river birch instead, which carries similar peeling bark with far better heat tolerance and borer resistance.

Uses & Benefits:

Chalky white peeling bark that carries the winter garden, with clear yellow autumn colour.

A fast, graceful specimen tree for cool northern gardens where it is properly suited.

Catkins and seed feed finches and other small birds; birches host a wide range of insect life.

Planting

How to Grow

Plant in autumn or early spring while dormant.
Choose a northern or eastern exposure in warmer regions.
Use moist, well-drained sandy or rocky loam.
Water deeply and regularly; birches are shallow-rooted.
Mulch widely to keep the root zone cool.
Prune only in summer or autumn, never in spring.

Pro Tip

Never prune a birch in late winter or spring; the cuts bleed sap heavily, so wait until summer or autumn.
