Materials Needed:

  • A large plastic bottle (2-liter size works well)
  • Marker
  • Sharp tool (awl or heated iron rod)
  • Water

Step-by-Step Guide:

  1. Prepare the Bottle: Clean the bottle and remove labels. Mark two lines on it – one approximately 15 centimeters from the bottom and another 10 centimeters from the neck.
  2. Create Water Outlet: Make a small hole about 7 centimeters from the bottle’s bottom.
  3. Fill the Bottle: Fill it with water up to the lower line and tighten the cap.
  4. Place the Bottle: Dig a hole near the plant and bury the bottle up to the marked line, with the hole facing the plant.
  5. Final Step: Fill the bottle completely, close the cap, and cover it with soil, leaving the neck exposed.


  • Efficient water use through targeted delivery to the root zone.
  • Reduces the need for frequent watering, saving time and resources.
