Automatic vegetable waterer using a plastic bottle

Creating an automatic vegetable waterer using a plastic bottle is a simple and effective way to ensure your plants receive consistent watering. Here’s a step-by-step guide:

Materials Needed:

  1. Plastic Bottle:
  • Choose a plastic bottle with a capacity suitable for the size of your garden or planters.
  1. Cap or Cork:
  • Find a cap or cork that fits the opening of the plastic bottle securely.
  1. Needle or Pin:
  • You’ll need a needle or pin to create small holes in the bottle for water to drip out.
  1. String or Twine:
  • Select a durable string or twine for hanging the bottle.
  1. Scissors:
  • Use scissors to cut the bottle and trim the string.


1. Prepare the Plastic Bottle:

  • Clean and empty the plastic bottle, removing any labels. Make sure it’s dry.

2. Create Holes in the Bottle:

  • Using a needle or pin, make small holes in the bottom of the plastic bottle. These holes will allow water to slowly drip out.

3. Cap the Bottle:

  • Securely attach the cap or cork to the bottle’s opening. This will prevent water from freely flowing out.

4. Cut the Bottle:

  • Cut the plastic bottle horizontally, approximately one-third of the way down from the cap. You will be left with the bottom part of the bottle.

5. Prepare the String:

  • Cut a length of string or twine, ensuring it is long enough to hang the bottle above your plants.

6. Make a Hole for Hanging:

  • Use the needle or pin to create a hole near the top of the bottle, close to the cut edge. Pass the string through this hole, creating a loop for hanging.

7. Hang the Waterer:

  • Hang the modified bottle above your plants, ensuring it is securely suspended.

8. Fill the Bottle:

  • Fill the top part of the bottle (the one with the cap) with water.

9. Adjust Water Flow:

  • Adjust the flow of water by loosening or tightening the cap. Experiment to find the right balance that provides a slow, consistent drip.

10. Monitor and Refill:

  • Monitor the water level in the bottle regularly. Refill as needed to maintain a steady water supply.

This DIY automatic vegetable waterer is a cost-effective solution for providing consistent moisture to your plants. Adjust the number of bottles based on the size of your garden, and hang them strategically for even coverage. This simple system is particularly useful for container gardens or hanging planters.
