Black mondo grass (Ophiopogon planiscapus): when to prune it?
Pruning is hardly needed. In March, clear away brown or damaged leaves before the new growth starts.
What else to prune in those months? March
Black mondo grass (Ophiopogon planiscapus): how to prune it?
- Cut or pull away dead, brown leaves at the base; fingers or a small rake work best.
- Never cut the whole tuft down: it grows slowly and recovers only slowly.
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.
