Mint takes over the entire garden bed

Aggressive runners spreading underground. Grow in a buried bottomless pot or a standalone container to confine roots.

Orange-brown pustules on leaf undersides

Mint rust, a fungal disease. Remove affected stems, improve airflow, and cut the plant back hard if widespread.

Too much shade or skipped harvesting. Give it morning sun and pinch tips regularly to force bushy growth.

Overcrowded, exhausted clump. Divide the plant every 2–3 years and replant healthy runners in fresh soil.
