How to prune spearmint

Cut back hard in midsummer after the first flowering; cut again in early autumn. Trim lightly as needed throughout the growing season.. Cut all stems back to 5–10 cm above soil level with scissors or shears. This triggers a flush of fresh, flavourful new growth. In winter, cut back dead top growth and the plant will reshoot from the roots in spring.

Cut back hard 2–3 times per season; light harvesting every 1–2 weeks. Spearmint is vigorous and benefits from regular cutting back to stay productive and prevent it from becoming woody and sprawling. Cut stems back by half after the first flush of growth, and again after flowering. In a pot, trim hard every few weeks to keep it compact. Divide congested clumps every 2–3 years and replant outer sections.
