Indian grass: when to prune it?
In March, just before the new shoots start to grow.
What else to prune in those months? March
Indian grass: how to prune it?
- Cut all stems and leaves back to about 10–15 cm above the ground.
- Tie the clump together with string first: this makes clearing up easy.
- Wear gloves, as the leaf edges of grasses can be sharp.
- The cuttings can go on the compost heap.
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: Do not cut in autumn: the seed plumes feed birds over winter and the clump protects its heart from wet and frost.
