Pruning horse mint — FAQ
When should I prune horse mint?
Midsummer after first flowering; early autumn; cut to ground level in late autumn. Shear all stems back to 3–4 inches above the ground after flowering to stimulate a fresh flush of growth. Trim regularly throughout summer to prevent the plant from becoming rank and coarse.
How often does horse mint need pruning?
Two to three times during the growing season; cut back to ground level each autumn. Horse mint is a tall, vigorous mint that spreads by runners and benefits from regular cutting back to keep it manageable and leafy. Cut stems down to a few inches in midsummer after the first flowering and again in early autumn. Remove dead top growth in late autumn or early spring. Containment is as essential as pruning.
