Growing celery in plastic bottles can be a practical and space-saving method. Celery does indeed grow relatively quickly and can adapt well to container gardening. Here’s a step-by-step guide to help you unlock the secret to growing celery in plastic bottles:

Materials Needed:

  1. Plastic Bottles: Choose large plastic bottles (2-liter or bigger) with caps.
  2. Celery Seeds or Celery Crowns: You can start celery from seeds or use celery crowns from store-bought celery.
  3. Potting Mix: A well-draining, nutrient-rich potting mix.
  4. Utility Knife or Scissors: To cut the plastic bottles.
  5. Watering Can or Spray Bottle: For watering the plants.
  6. Fertilizer: A balanced, water-soluble fertilizer.
  7. Labels or Markers: To identify the type of celery and planting date.

Steps:

  1. Prepare the Plastic Bottles:
    • Clean and rinse the plastic bottles thoroughly.
    • Using a utility knife or scissors, cut the bottles in half horizontally. You will use the upper part as a growing container.
  2. Create Drainage Holes:
    • Poke or cut several drainage holes in the bottom of each bottle to ensure proper water drainage.
  3. Fill Bottles with Potting Mix:
    • Add well-draining potting mix into the upper part of the plastic bottle, leaving some space at the top.
  4. Plant Celery Seeds or Crowns:
    • If using seeds, plant them according to the recommended depth on the seed packet.
    • If using celery crowns, cut about 2 inches from the bottom of store-bought celery, and plant the cut end in the potting mix.
  5. Watering:
    • Water the soil thoroughly after planting.
    • Keep the soil consistently moist but not waterlogged. Celery prefers consistently moist conditions.
  6. Sunlight:
    • Place the bottles in a location with partial to full sunlight. Celery prefers cooler temperatures and can tolerate partial shade.
  7. Fertilizing:
    • Once the celery has established, fertilize it with a balanced, water-soluble fertilizer according to the package instructions.
  8. Thinning (Optional):
    • If you started celery from seeds and they are crowded, thin the seedlings to allow proper spacing.
  9. Harvesting:
    • Celery can be harvested when the stalks are large enough to use. Cut outer stalks at the base when you’re ready to harvest.
  10. Maintain and Replant:
    • Regularly check the soil moisture, and water as needed.
    • Celery is a biennial, so if you want to try regrowing from the base, leave some of the plant in the container and see if new growth emerges.

Growing celery in plastic bottles is a space-efficient way to enjoy this versatile vegetable, especially if you have limited garden space. Adjust care based on the specific needs of your celery variety and growing conditions.
