Prof. Martin Thorne, Ph.D.When growing mint in a container, it will not spread and become invasive, allowing you to place it anywhere without concern. As a bonus, containers contain aggressive roots, so you can prevent garden takeovers because they are in a container. I have grown mint on sunny balconies and shady patios for about ten years. It works well for urban gardeners and those with limited space.
Pot Requirements
- Choose containers at least 12 inches wide for root development
- Ensure drainage holes prevent waterlogged soil conditions
- Light-colored pots reduce heat absorption in sunny locations
Soil Preparation
- Mix potting soil with perlite for improved drainage
- Add compost for slow-release nutrients throughout the season
- Maintain pH between 6.0-7.0 for optimal growth
Placement Strategy
- Position containers near water sources for easy irrigation
- Elevate pots for air circulation and pest prevention
- Use wheeled bases for seasonal light adjustments
Water container plants whenever the top inch is dried out. You can stick your finger in the soil to gauge moisture depth. Water enough to allow for proper drainage and prevent salt buildup. Self-watering pots can help while away on vacation. In hot summer weather, a layer of pebbles helps reduce evaporation.
Rotate the pots weekly for even growth. Mint tends to lean towards the light source, leading to uneven growth. By rotating the pots a quarter turn each week, each side will receive even exposure to sunlight, preventing the mint from becoming leggy while promoting bushier, compact plants.
Seasonal care protects potted mint plants. Move containered mint inside before frost. Provide grow lights for 6-8 hours daily during winter. Trim back ⅓ of the plants to conserve energy in the fall. Outdoor pots should be insulated against freezing temperatures (use bubble wrap in cold zones).
Refresh the soil every spring for continued productivity. Remove mint gently from containers. Trim circling roots. Replace with fresh potting mix enriched with compost. Divide overcrowded plants during this process.
