Pruning japanese blood grass — FAQ
When should I prune japanese blood grass?
Late winter to early spring, before new growth. Shear to 3–4 inches above ground. Immediately remove any fully green shoots at the base — these are genetic reversions to the invasive species.
How often does japanese blood grass need pruning?
Annually; check for reversions throughout the season. Japanese blood grass needs only an annual tidy. Cut the clump back to 3–4 inches above ground in late winter or early spring before new red-tipped blades push through. No deadheading is needed since flowers are insignificant. Watch for any all-green revertant shoots and remove them promptly at the base to prevent the plant reverting to its invasive parent form.
