Tufted hair grass: when to prune it?

In March, before the new leaves really start growing. Not in autumn: the plumes still look good in winter and feed the birds.

What else to prune in those months? March

Tufted hair grass: how to prune it?

  1. Cut the old flower stems off short, just above the clump.
  2. Comb out the dead leaves with your fingers or a small rake. Wear gloves, as the leaves are rough.
  3. If the clump looks very untidy you can cut it back to 10–15 cm, but spare the green leaves as much as possible.
  4. Put the clippings on the compost heap.

How much to cut, and how often?

  • One pruning period a year: March.

What does it mean for wildlife?

  • If you only cut back in March, the old stems stand through the winter: insects overwinter in them and birds eat the seeds.
  • As a native plant, it feeds more insects than a non-native species.

Caution: If you do not want seedlings, cut off the plumes before the seed is ripe. You will then have less winter interest and less food for birds.
