Wavy hair grass: how to prune it?

  1. In March, remove dead leaves from the tuft with gloved hands or a small rake.
  2. From August, cut spent panicles off just above the foliage if you do not want seedlings.
  3. Do not cut the tuft itself short: the green foliage is its ornamental value in winter too.

How much to cut, and how often?

  • There are 2 pruning periods a year: March and August. You don’t have to prune in every one.

What does it mean for wildlife?

  • As a native plant, it feeds more insects than a non-native species.
