Sea aster: when to prune it?

Late February–March, before the new shoots appear.

What else to prune in those months? March

Sea aster: how to prune it?

  1. Leave the faded stems with their fluffy seed heads standing all winter.
  2. Cut them back in late February–March to just above the new leaf rosette.
  3. If you want fewer seedlings, cut off the faded heads in October before they release their fluff.

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.
