Amazing method to grow mint in plastic cups. The results exceeded expectations

By Lesia

Growing mint in plastic cups is a simple and effective way to have fresh mint readily available. Here’s a method that likely led to those amazing results:

Method:

  1. Cuttings or Root Division:
    • Cuttings: Take healthy stem cuttings from an existing mint plant. Choose stems with several leaves.
    • Root Division: If you have a mature mint plant, you can divide the roots. Gently separate the plant into sections, ensuring each section has roots and stems.
  2. Preparation:
    • Cuttings: Remove the lower leaves from the cuttings, leaving a few leaves at the top.
    • Root Division: Ensure the root divisions have healthy roots.
  3. Planting:
    • Use clear plastic cups. This allows you to monitor root growth.
    • Fill the cups with a well-draining potting mix. A mixture of potting soil and perlite or vermiculite is ideal.
    • Moisten the potting mix.
    • Plant the cuttings or root divisions in the cups, ensuring the stems are upright.
    • For cuttings, insert the cut end into the soil.
  4. Watering and Light:
    • Water the mint gently, keeping the soil consistently moist but not waterlogged.
    • Place the cups in a bright location with indirect sunlight. Mint thrives in sunlight, but direct, intense sunlight can scorch young plants.
    • A south or east-facing window is often ideal.
  5. Humidity (Optional but Helpful):
    • To increase humidity, you can cover the cups with clear plastic wrap or a plastic bag. This creates a mini-greenhouse effect.
    • Ensure there’s some airflow to prevent mold growth.
    • Remove the cover once the plants establish roots and new growth appears.
  6. Root Development:
    • You’ll start to see root growth through the clear plastic cups within a few weeks.
    • Once the roots have filled the cup, you can transplant the mint into larger pots or into the garden.
  7. Ongoing Care:
    • Mint is a vigorous grower, so regular pruning will encourage bushy growth.
    • Water the mint when the top inch of soil feels dry.
    • Fertilize with a balanced liquid fertilizer every few weeks during the growing season.

Why This Method Works:

  • Clear Cups: Allow for easy monitoring of root development.
  • Well-Draining Soil: Prevents root rot.
  • Adequate Light: Mint needs light to thrive.
  • Consistent Moisture: Keeps the plants hydrated.
  • Humidity (Optional): Helps cuttings root faster.

Tips for Success:

  • Use fresh, healthy cuttings or root divisions.
  • Avoid overwatering, as this can lead to root rot.
  • Provide adequate airflow to prevent mold.
  • Pinch off flower buds to encourage leaf growth.
  • Mint spreads easily, so consider growing it in containers to control its growth.
