Great yellow gentian: when to prune it?
In March, before the new leaves appear. The dry flowering stems can stay standing all winter.
What else to prune in those months? March
Great yellow gentian: how to prune it?
- Leave the faded stems with their seed capsules through autumn and winter: they look lovely with frost on them and insects shelter in them.
- In March, cut the dead stems and withered leaves off just above the ground.
- Mind the bud at the top of the root: that is where the new leaves come from. Do not cut into it.
- Don’t want seed? Then cut off the flowering stem after flowering, at the end of August.
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.
Caution: Never dig around the plant: a damaged taproot recovers poorly.
