Branched bur-reed: when to prune it?

In March, before the new leaves appear. Leave the old leaves and the seed heads standing over winter.

What else to prune in those months? March

Branched bur-reed: how to prune it?

  1. Cut the old, brown leaves and flower stems off just above the water surface.
  2. Remove leaves that fall into the water in autumn earlier, so they do not rot on the bottom.
  3. Ideally leave the seed heads until winter: ducks and other birds eat the seeds.

How much to cut, and how often?

  • One pruning period a year: March.

What does it mean for wildlife?

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

Caution: It also self-seeds through its floating fruits. Cut off the seed heads in autumn if you do not want new plants.
