Cutting deutzia - tips for cutting the ornamental shrub

Stimulate a second flower by pruning

Deutzia belong to the slow-growing trees. Many gardeners therefore forego an annual cut. This saves a lot of work if the Deutzias are planted as a hedge.

If you tend the shrub as a single plant in the garden, you should definitely use scissors in spring. Pruning immediately after flowering stimulates the formation of new flowers in autumn. You can then enjoy the pretty flower clusters twice a year.

Cut back the Deutzia after flowering

  • Cut back by a third
  • Remove weak shoots
  • Shorten shoots that are too long
  • Thinning out the bush

The best time to prune Deutzias is June, early July, when the shrub has withered.

Cut the dead shoots down to a third. Always make the cut directly above a bud that is facing outwards.

When cutting, make sure that the Deutzia keeps a nice shape. Remove weak shoots and shorten any protruding branches. Light up branches that are too close together so that the middle of the bush receives enough light.

Remove old wood when rejuvenating

After two to three years, it's time to make a taper cut. In doing so, you remove all old, lignified shoots. Cut the old branches as close as possible to the root neck. You usually need a pruning saw for this.

The tapering cut should then be made every two years to encourage the Deutzia to develop young shoots.

Opinions differ about when the ideal time for a rejuvenation cut is. Some gardeners advise making the rejuvenating pruning in late winter, while others recommend pruning right after flowering.

Cut cuttings for propagation

If you want to plant an entire hedge of deutzias, cut cuttings in the summer to propagate the plant. Use a shoot that grows in the middle of the shrub for this.

Cut off a 20 to 30 cm long piece that is not completely lignified. The lower leaves are removed and the cutting is placed in a pot with germ-free potting soil.

The pot needs to be bright but not in direct sunlight. Keep the soil evenly moist to allow roots to form. Avoid too much moisture because the cuttings will rot.


The non-toxic deutzia are very robust and easy to care for. The soil should be well drained and rich in nutrients. The hardy shrub only blooms abundantly if it receives enough sun in its location.
