Prof. Charles Hartman, Ph.D.To grow mint successfully you need to consider its double life as a tough herb that can also be an aggressive colonizer. Mint can survive in a variety of climates ranging from USDA zones 3-11, but without proper management, it will take over a garden. My first mint patch invaded my strawberry beds in just a couple of months - now I employ careful cautionary measures.
Soil Requirements
- pH 6.0-7.0 - Use test kits quarterly
- Drainage - 30% perlite in potting mixes
- Nutrients - Monthly 10-5-5 fertilizer applications
Light & Water Balance
- 4-6 hours morning sunlight minimum
- Water when top 1" soil dries
- Reduce hydration in winter by 50%
Container gardening is the most effective approach to controlling the spread of mint. Use pots that are at least 12" deep and contain a drainage hole. I like all of my pots with landscape fabric to block escaping roots. Elevate the pots on stands to gain better airflow and inspect for pests more easily.
Preventative Measures
- Companion planting with marigolds
- Weekly neem oil leaf sprays
- Rotate pots to disrupt pest cycles
Active Infestations
- Alcohol swabs for mealybugs
- Garlic spray for spider mites
- Diatomaceous earth for ants
Collect mint leaves in the morning after the dew has dried. Cut stems right above the leaf nodes with sanitized garden shears - this will promote bushier regrowth. I manage to gather enough each week for teas, plus enough frozen mint cubes to utilize summer's prime flavor through winter.
