Check out this DIY Drip Irrigation System made from plastic bottles (2-liter), milk jugs or any other type of plastic bottle. Punch 2 holes into the sides, 2 holes into the bottom and plant bottles next to plants. Fill the bottles with water and your plants will get a slow steady water drip. If you screw the caps back onto the bottles after refilling, the water is released slower and it will not evaporate.
