Pruning and nipping

Pruning

At the end of winter, just before the spring sprouting.

Nipping

In late spring, trim new growth to two or three leaves. Flowers will appear on the new shoots, so trim again in autumn after flowering.

Curiosities

The Japanese name of this plant Sarusuberi, means “where the monkey slips” because of the smoothness of its bark. We can find different varieties with different colours of flowers from pale pink to different shades of white.
