Growing bok choy in plastic bottles is a creative and space-saving gardening method. Here’s a simple guide to help you discover the secret to growing bok choy easily in plastic bottles:

Materials Needed:

  1. Plastic Bottles: Clean and sanitize plastic bottles with the labels removed. Larger bottles, such as 2-liter soda bottles, work well.
  2. Potting Soil: Choose a well-draining potting mix suitable for vegetables.
  3. Bok Choy Seeds or Seedlings: Purchase high-quality bok choy seeds or young seedlings.
  4. Utility Knife or Scissors: To cut and prepare the plastic bottles.
  5. Watering Can or Spray Bottle: For watering the plants.
  6. Optional: Fertilizer


  1. Prepare Plastic Bottles:
    • Cut the plastic bottles horizontally, removing the top section. Ensure that the remaining bottom section provides sufficient depth for the bok choy roots.
  2. Poke Holes for Drainage:
    • Use a nail or the tip of scissors to poke several drainage holes at the bottom of each plastic bottle. Adequate drainage is crucial for plant health.
  3. Fill Bottles with Soil:
    • Fill each plastic bottle with potting soil, leaving about an inch from the top to prevent soil spillage when watering.
  4. Plant Bok Choy Seeds or Seedlings:
    • If using seeds, sow them according to the recommended spacing on the seed packet. If using seedlings, transplant them into the soil.
  5. Watering:
    • Water the bok choy thoroughly after planting. Ensure the soil is consistently moist but not waterlogged.
  6. Place in Sunlight:
    • Position the plastic bottles in a location that receives partial to full sunlight. Bok choy generally prefers cooler temperatures and can tolerate some shade.
  7. Optional Fertilization:
    • If your potting mix doesn’t contain fertilizer, you can use a balanced, water-soluble fertilizer diluted to half strength every 2-3 weeks.
  8. Maintain Moisture:
    • Keep the soil consistently moist throughout the growing period. Bok choy prefers well-hydrated conditions.
  9. Thinning (If Necessary):
    • If you’ve planted bok choy seeds and they germinate densely, thin the seedlings to provide adequate space for each plant.
  10. Harvesting:
    • Bok choy is typically ready for harvesting within 40-60 days, depending on the variety. Harvest when the leaves are of suitable size, and the plant is mature.
  11. Continuous Harvest:
    • Bok choy can often be harvested more than once. Cut leaves at the base, allowing the plant to produce new growth for future harvests.


  • Variety Selection: Choose bok choy varieties that are well-suited for container gardening and have a relatively compact growth habit.
  • Container Size: Consider the size of the plastic bottles; smaller varieties of bok choy may be more suitable for smaller containers.
  • Vertical Gardening: If you have limited horizontal space, consider hanging the plastic bottles vertically.
  • Protect from Extreme Heat: Bok choy prefers cooler temperatures, so provide shade or protection during heatwaves.

Growing bok choy in plastic bottles is a fun and sustainable way to enjoy fresh, homegrown greens. It’s suitable for small spaces, balconies, or windowsills, making it an accessible option for urban gardeners. Adjust the care routine based on your specific growing conditions and enjoy the process of cultivating your own bok choy.
