Pruning acorus gramineus — FAQ
When should I prune acorus gramineus?
Early spring; dead tips can be trimmed year-round. Use scissors to trim brown leaf tips or cut away dead outer leaves at the base. Avoid cutting into healthy green tissue. Divide congested clumps in spring to maintain plant health.
How often does acorus gramineus need pruning?
As needed for cosmetic tidying; rarely requires more. Acorus gramineus (Japanese rush) needs only light grooming. Comb out or trim dead or brown leaf tips and any tatty outer leaves with scissors. There is no benefit to cutting the whole plant back hard — it is slow-growing and does not flush vigorously after severe pruning. Keep it tidy rather than reshape it.
