Whether pampas grass, sedge, fountain grass, elephant grass, riding grass or another specimen - ornamental grasses are popular plants for heather, rock and perennial gardens. In order for them to remain vigorous for many years, they should be cut regularly. But when?
Ornamental grass is best cut in spring
Preferably cut in spring
Fall is not a good time to cut back ornamental grasses. The main reason not to do this is that the cut stems can allow moisture to seep in, flow down and cause rot in the root area. It is better to cut back in the spring between mid-February and (at the latest) mid-April - before the plant starts to sprout again.
Other advantages of spring pruning for almost all types of ornamental grass are:
- Culms protect against the cold and thus increase winter hardiness
- Plants can self-seed
- Shelter for insects and birds is guaranteed
tips
Evergreen ornamental grasses do not need to be cut. It is sufficient to pluck out old and dead parts.
