Valerian: how to prune it?

  1. Cut faded flower stems down to just above the leaf rosette.
  2. Leave the leaf rosette: it stays green into autumn.
  3. In March, cut away dead leaves and stems before new growth begins.

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?

  • Valerian flowers in June–August, when it attracts bees and butterflies.
  • If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
  • As a native plant, it feeds more insects than a non-native species.
