Troubleshooting
Moroccan Mint problems — and how to fix them
Moroccan Mint (Mentha spicata 'Moroccan') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Mint rust
Orange-brown pustules on leaf undersides; remove infected stems, improve airflow and avoid wetting foliage. Severe cases warrant cutting the plant to the ground.
Aggressive spreading
Runners colonize beds fast. Grow in containers or a sunken bottomless pot to keep it in check.
Bitter, tough leaves
Drought stress and old growth coarsen flavor. Water steadily and harvest young tip growth for the sweetest tea leaves.
Powdery mildew
White film in humid, crowded plantings; thin stems and increase spacing to keep air moving.
