How to grow bitter melon in recycled, wall-mounted plastic bottles

Growing bitter melon (Momordica charantia) in recycled, wall-mounted plastic bottles is a creative and space-efficient idea, especially if you don’t have access to a traditional garden. Here’s a step-by-step guide to help you set up your vertical bitter melon garden using plastic bottles:

Materials Needed:

  1. Plastic Bottles: Collect empty plastic bottles (2-liter or larger) for the vertical planters.
  2. Bitter Melon Seeds or Seedlings: Obtain bitter melon seeds or seedlings from a reliable source.
  3. Potting Mix: Use a well-draining potting mix suitable for container gardening.
  4. Support Structure: Create or install a vertical support structure, such as a wooden frame, trellis, or wall-mounted wire system.
  5. Scissors or Craft Knife: To cut the plastic bottles.


  1. Collect and Prepare Plastic Bottles:
    • Collect a sufficient number of plastic bottles. Cut each bottle horizontally, removing the top portion. The bottom part will serve as a planter.
  2. Create Drainage Holes:
    • Make several small drainage holes in the bottom of each plastic bottle to ensure proper drainage.
  3. Fill Bottles with Potting Mix:
    • Fill each plastic bottle with the potting mix, leaving some space at the top.
  4. Plant Bitter Melon Seeds or Seedlings:
    • Plant bitter melon seeds or seedlings in each bottle. Follow the recommended planting depth and spacing guidelines for bitter melon.
  5. Watering:
    • Water the plants thoroughly after planting. Ensure the soil stays consistently moist but not waterlogged.
  6. Attach Bottles to Support Structure:
    • Attach the plastic bottles to the support structure. This can be done by using wire, zip ties, or any secure method. Ensure that the bottles are stable and won’t fall.
  7. Vertical Arrangement:
    • Arrange the bottles vertically to make the most of the available space. You can set them up against a wall or on a frame.
  8. Training Vines:
    • As the bitter melon plants grow, gently guide the vines to climb the support structure. Bitter melon plants are climbers and will naturally use the support to grow vertically.
  9. Regular Maintenance:
    • Monitor the plants for water needs, pests, and diseases. Provide additional support for the vines as they grow.
  10. Harvesting:
    • Harvest bitter melon when they reach the desired size. Regular harvesting encourages the plant to produce more fruits.


  • Sunlight: Place your vertical garden in a location that receives plenty of sunlight, preferably 6-8 hours a day.
  • Feeding: Supplement the plants with a balanced liquid fertilizer according to the manufacturer’s instructions.
  • Varieties: Choose bitter melon varieties that are suitable for container gardening.
  • Companion Planting: Consider companion planting with herbs or flowers to deter pests and attract beneficial insects.
  • Rotate Bottles: Rotate the bottles occasionally to ensure that all sides of the plants receive adequate sunlight.

By recycling plastic bottles and implementing a vertical gardening approach, you can effectively grow bitter melon without the need for a traditional garden. This method not only maximizes space but also allows for better air circulation, which can be beneficial for plant health.
