Cotinus (Smoke Bush)
Smoke bushes are at their best when grown in full sun, they prefer well drained good soil for good results. Although pruning is not strictly necessary, if they are cut back to 2-3 buds in late Winter or early Spring, the intensity of colour in the foliage display is improved and leaf size is increased. At the same time any diseased or congested branches can be removed to maintain a good framework.
A generous mulch in early Spring will also help to retain moisture and improve the show of foliage.
