Jumpseed (Persicaria virginiana): how to prune it?
- Cut off the withered stems and brown leaves just above the ground.
- In summer, cut off damaged or scorched leaves.
- Cut off the flower spikes before the seed ripens to limit self-seeding.
- Remove seedlings with plain green leaves: they are less ornamental.
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.
