Pruning and caring for spirea

Once properly installed, spirea requires very little care and maintenance.

Delete withered flowers gradually to extend the flowering period as much as possible.

Spirea can, like all shrubs, not be pruned.

But by pruning your spirea just after flowering, you will improve the next flowering, in quality and quantity.

The spring flowering species are pruned just after the flowers have fallen.

The summer flowering species are pruned at the end of winter, around March.

  • Start by removing the withered branches at the base.
  • Remove the oldest wood to stimulate the emergence of new growth.
  • Clear the center of the spirea while restoring a balanced silhouette to your shrub.
