Drip irrigation systems concentrate the amount of water delivered to your plants. These systems are more efficient than watering the soil with a mister or hose, which allows the sun to evaporate a lot of the moisture before it reaches your plants’ roots. Drip irrigation delivers water directly to your plants so they require less water. Irrigation systems can be expensive, but you can save money and be green by recycling household items into your own irrigation system. All you need are a few simple tools.
Things You'll Need
- Empty water bottles
- Garden hoses
- Electric drill
- Narrow-spout watering can
Drill holes about 1/16 inch in a circle 1 inch apart on the bottom and in straight lines on the sides of each water bottle.
Lay out a length of old garden hose and punch holes in it with an awl. Keep the holes in a straight line, 1 inch apart.
Dig holes in the center of small circular plots and next to single clumps of plants. The holes should be about 1/3 less deep and as wide as your water bottles. Bury a 12-inch-long, 3-inch-wide water bottle in a hole about 8 inches deep and 3 inches wide. Smooth the soil around each bottle.
Fill each of your bottles with water from a narrow-spout watering can, refilling them about once a week.
Dig trenches in large garden plots that zigzag between the rows. The trenches should be about 6 inches deep and no more than 2 inches wide. Lay your punched hose in this trench, leaving one open end of it sticking up out of the ground where you can find it. Screw an intact hose to this opening and turn the water pressure on low for about four hours in the morning and an additional hour at night.
