In March, before the new shoots start to grow; in between, you can cut the main spikes back after flowering.

What else to prune in those months? March

Garden speedwell: how to prune it?

  1. Cut last year’s dried stems down to just above the ground.
  2. During flowering, cut the main spikes for a bouquet: the side shoots then often keep flowering.
  3. In autumn, leave a few stems standing as winter decoration and shelter for insects and birds.

How much to cut, and how often?

  • One pruning period a year: March.

What does it mean for wildlife?

  • Garden speedwell flowers in July–September, when it attracts bees and butterflies.
  • If you only cut back in March, the old stems stand through the winter: insects overwinter in them and birds eat the seeds.
