When and how to cut back Cotinus coggygria 'Royal Purple'
Under favourable conditions, and once mature, you can expect Cotinus coggygria 'Royal Purple' to reach and height of between 4-8 metres! Which of course will make it far too large for most people's gardens.

As a rule, pruning is not required, although straggly growths can be shortened or removed in March. Oversized specimens can be coppiced to maintain a manageable size. This will also encourage the plant to produce larger leaves but this will be at the expense of the following seasons blooms.

Coppicing is a pruning technique where a tree or shrub is cut to ground level. Cut all stems of Cotinus coggygria 'Royal Purple' to within 5-7.5cm of ground level. This can be done in late winter or early spring, just before they come into active growth. Be aware that on older specimens it can take a coupe of seasons to come back into growth,
