Materials Needed To Plant Eggplant in Plastic Bottles

Before getting started growing aubergines in plastic bottles, you need to gather the necessary materials. Here’s a list of the things you’ll need:

  • Plastic bottles (2-liter size)
  • Potting soil or garden soil
  • Compost
  • Eggplant seedlings
  • Scissors or a cutter
  • Watering can
  • Fertilizer

Preparing the Plastic Bottles

Preparing the Plastic Bottles

Plastic bottles can be repurposed for a variety of uses, including as planters for growing fruits, vegetables, and flowers. Before using plastic bottles as planters, it is important to prepare them properly to ensure optimal plant growth. 

Here’s the step-by-step process of preparing plastic bottles to lant eggplant in plastic bottles.

  1. Clean the Bottles: Start by cleaning the plastic bottles thoroughly with soap and water to remove any dirt, debris, or bacteria that may be present. Give the bottles a thorough rinse and allow them to dry completely.
  2. Cut the Bottles: Using a pair of scissors or a cutter, cut off the top of the bottle, leaving the bottom part intact. The top of the bottle will serve as a lid for the planter, while the bottom will hold the soil and plant.
  3. Make Drainage Holes: Using a sharp object like a knife or scissors, make drainage holes at the bottom of the bottle. These holes will allow excess water to drain out and prevent water from accumulating at the bottom, which can cause root rot.
  4. Add Soil: Add a layer of soil to the bottom of the bottle, filling it up to about one-third of the height of the bottle.
  5. Add Compost: Add a layer of compost on top of the soil. Compost is rich in nutrients and will help nourish the plant.
  6. Add Soil Again: Add another layer of soil on top of the compost, filling the bottle almost to the top. Leave a small gap between the top of the soil and the top of the bottle to allow for watering.
  7. Water the Soil: Slowly water the soil, making sure that the water is absorbed evenly throughout the soil. To avoid causing root rot, take care not to overwater the bottle soil.

You can create an inexpensive and environmentally friendly method of growing your own fruits, vegetables, and flowers by preparing your plastic bottles for planting using these easy steps.

Growing plants from seeds in plastic bottles is a fulfilling and rewarding experience. Proper seedling preparation is crucial to ensuring that your plants get off to a healthy start. 

Here’s the step-by-step process of preparing your seedlings for planting aubergines in plastic bottles.

  • Choose the Right Seeds: Select high-quality seeds from a reputable source. Check the seed packet for information on planting depth, spacing, and germination time.
  • Prepare Seed Trays: Fill seed trays with a seed-starting mix. Make sure the mixture is evenly damp but not soggy by adding water to it.
  • Plant the Seeds: Plant the seeds according to the instructions on the seed packet. Most seeds should be planted at a depth of about two to three times their diameter. Cover the seeds with a thin layer of seed-starting mix.
  • Water the Seeds: Using a spray bottle or watering can water the seeds gently. Be careful not to dislodge the seeds or disturb the soil.
  • Provide Proper Lighting: Place the seed trays in a warm, well-lit area. Most seedlings require 12 to 16 hours of light per day. If natural light is not available, consider using fluorescent or LED grow lights.
  • Maintain Adequate Humidity: Cover the seed trays with plastic wrap or a humidity dome to maintain sufficient humidity. Remove the cover once the seedlings have emerged.

You can get your seedlings ready for strong growth and a good eggplant harvest by adhering to these straightforward steps.

Apply a balanced fertilizer (10-10-10) every one to two weeks during the growing season. You can use a water-soluble fertilizer or an organic fertilizer like compost tea.

Maintenance and Care

Keep the soil in bottles free of weeds, as they can compete with the eggplants for water and nutrients. Check the plants regularly for pests and diseases, and take appropriate action if necessary. Staking the aubergine plants may also be necessary to keep them upright as they grow taller. You can use sticks or wooden stakes to support the plants in plastic bottles.

Harvesting Eggplants From Plastic Bottles
