There is no doubt that dogwoods (Cornus) are an essential plant for the winter border, as they have such colourful winter stems. The effect of rich red, orange, yellow or bright green multiple stems in winter light is stunning, especially when planted in large groups by water.

Dogwoods combine well in borders with the white winter stems of the ghost bramble (Rubus cockburnianus or R. thibetanus) for contrast, and also look good with emerging early spring bulbs.

Perhaps because this has become a planting trend in recent years, gardeners have become a little over-zealous in coppicing or pruning  dogwoods to get those desirable colourful stems. As a result, plants are often pruned too early in their life span, with disappointing results.

Dogwoods grown for their colourful stems are different to those grown for their summer flowers – read our feature on the best flowering dogwoods.

How to prune dogwood

The trick for getting the best out of dogwoods is to let them establish for three to four years before you coppice for the first time. Then cut back hard every other year for the colourful stems.

When to prune dogwood

Prune dogwood in early spring, before the plants have started into leaf. Much of the work can be carried out with a pair of good, sharp secateurs, because stems are relatively thin. But for thicker stems, always use a small, sharp pruning saw, as long-handled loppers can squash the ends of the cut and bruise the stems, which ultimately leads to die-back and rotting.

Cut back to around 7-10cm from the ground. This encourages a better shape for the new growth. Mulch generously after cutting. For more on coppicing, read our piece on how to coppice hazel

This established dogwood, Cornus alba ‘Sibirica’, hasn’t been cut back for a couple of seasons and is now about 1.5m tall and wide.

Pruning in winter will keep the stems compact and colourful the following winter. The ‘stool’ should have a smooth, clean finish to encourage healthy new stem growth. Cut back to between 7cm and 10cm from the ground.

After a summer of growth, the dogwood has worked hard to generate lots of dense new stems. Once the leaves have fallen, their rich red colour can be enjoyed.
