When to plant and prune Beech
Beech flowers from mid April to early May and the dates below cover planting, flowering and the pruning window.
Planting, flowering and pruning by region
Beech is grown to the calendar rather than to the frost, so the same dates apply across the whole UK and every region below reads the same. Where a plant’s timings do follow the frost, Plot shifts them from the Midlands and Lowland Wales baseline using Met Office average frost dates.

Growing notes
Deciduous, but a clipped beech hedge holds its coppery dead leaves through winter, so it screens almost as well as an evergreen while looking far softer. It needs well-drained soil: on heavy wet ground or in a frost pocket plant hornbeam instead. As a free-standing tree it reaches 25m by 15m, so only the clipped hedge belongs in a garden.

Feeding
A general purpose fertiliser in February helps newly planted hedges; discontinue once established.
Pruning: what to avoid
Trim in late summer, not spring, or you cut off the growth that carries the winter leaves. Do not cut hedges between March and August without checking first: under the Wildlife and Countryside Act 1981 it is an offence to damage or destroy the nest of any wild bird while it is in use or being built, and the main UK nesting season runs from about early March to August.
Pruning group
Trim once a year in late summer (August)
Bare-root season
Bare-root stock is lifted and sold while dormant, from early November to late February. Container-grown plants can go in at other times of year, but bare-root is cheaper and establishes well.
What usually goes wrong
- fails on waterlogged clay
- beech aphid and felted beech scale
- honey fungus
- bare bases if trimmed only on top
