Pruning moudry black fountain grass — FAQ
When should I prune moudry black fountain grass?
Deadhead plumes in late summer (August) to prevent self-seeding; cut back the clump in late winter (February–March). Cut spent plumes at the base as soon as they finish flowering and before seed ripens. In late winter, tie and cut the whole clump to 3–4 inches. This two-step approach manages both appearance and unwanted spread.
How often does moudry black fountain grass need pruning?
Twice per season (deadhead in summer; hard cutback in late winter). Moudry Black Fountain Grass needs one hard cutback per year. Note: 'Moudry' self-seeds aggressively — deadheading the near-black plumes before seed set in mid-to-late summer is strongly recommended to prevent unwanted seedlings. Otherwise cut the dormant clump to 3–4 inches in late winter before warm-season growth resumes.
