Culinary Notes


Chef's Note

Kentucky Colonel spearmint is the kind of mint that smells like a cold glass even before it hits your tongue—crush it and you’ll get that clean, menthol-green rush. Use it fresh or as a short steep/infusion so the volatile aroma stays sharp rather than turning dull.

Best Uses

  • freshly crushed over fruit and summer drinks
  • steeped for tea or muddled into lemonade and sodas
  • made into quick mint syrup for cocktails and yogurt
  • folded into herb salads where it stays fragrant, not swampy

Frequently Asked Questions


What pest or disease most commonly affects Mentha spicata (spearmint) and how can I manage it at home?
Spearmint commonly suffers from mint rust (orange/brown pustules on leaves) and fungal spotting when leaves stay wet. Water at the soil line in the morning, improve airflow by thinning dense growth, and remove infected leaves early; for persistent rust, use a labeled fungicide for ornamentals/herbs and repeat per label instructions.
How often should I water Mentha spicata during its main growing phase to keep soil moisture right?
During active growth, keep the top 1 inch of soil consistently evenly moist but not waterlogged; this mint is happiest with steady moisture under full sun. In hot weather this usually means watering about 1–2 times per week, more often if the soil dries quickly—always water thoroughly, then let the surface start to dry slightly before the next watering.
How do I know when Kentucky Colonel spearmint (Mentha spicata) is ready to harvest at around 60 days?
Start harvesting when plants reach a productive size—typically around day 50–60—and have multiple sets of healthy, fully expanded leaves on strong stems. Snip stems just above a leaf pair to encourage branching; the best flavor comes from harvesting before the mint sends up heavy flowering spikes (early growth is usually most aromatic).
