Blue globe thistle: when to prune it?
Cut the dead stems away in March, just before new growth starts. In summer, only cut flowers for the vase or remove spent globes.
What else to prune in those months? March
Blue globe thistle: how to prune it?
- In March, cut all old stems down to just above the ground, above the young leaves.
- Wear sturdy gloves: the old stems and leaves are prickly.
- In summer, remove spent globes if you want to avoid seedlings.
- For dried flowers, cut long stems just before the globes are fully open and hang them upside down to dry in a dark, airy place.
How much to cut, and how often?
- One pruning period a year: March.
What does it mean for wildlife?
- Blue globe thistle flowers in July–September, when it attracts bees and butterflies.
- If you only cut back in March, the old stems stand through the winter: insects overwinter in them and birds eat the seeds.
Caution: Do not cut off the seed heads in autumn if you want to help the birds: goldfinches eat the seeds in winter.
