How to prune common box

Best time
Late spring (after the first flush of growth settles, typically late May to June in UK) and again in late summer (August); avoid hard frosts
How often
2-3 times per growing season for formal shapes; once annually for informal hedges
Technique
Use sharp hand shears or electric trimmers to clip to the desired shape. Cut just into the current season's green growth, not into old leafless brown wood unless renovating. For renovation, cut back hard in late spring and feed well — box regrows reliably from old wood.

How often does common box need pruning?

2-3 times per growing season for formal shapes; once annually for informal hedges. Common box (Buxus sempervirens) is a classic hedging and topiary shrub that needs regular clipping to stay dense and shapely. Left unclipped it becomes open and ungainly. Clip formal hedges and shapes two to three times during the growing season. Avoid clipping in hot midday sun, which can scorch freshly cut leaf edges.
