It’s easy to make DIY houseplant drip irrigation using nothing more than a plastic water bottle.

To make drip irrigation for houseplants:

  1. Drill a 1/8” diameter hole in the lid of a plastic water bottle.
  2. Fill the bottle with water.
  3. Screw the lid tightly on the bottle.
  4. Dig a small hole in the soil of the houseplant.
  5. Insert the water bottle upside down in the hole.

The water will slowly leak out over time, keeping the plant well irrigated while you’re away from home on vacation. Watch this video to find out more.


Joe Truini: Drip irrigation is an ideal way to water a row of plants or vegetable beds or even flower beds; because it delivers a precise amount of water exactly where you need it without over watering.

I want to take the benefits of drip irrigation, add it to houseplants, and here’s what I came up with. All you need is an empty plastic bottle and drill an eighth-inch diameter hole in the cap, and that is the drip irrigation system right there.

So, you go to your houseplant and get a stick or a screwdriver, and make a little bit of a hole in the back of the pot—just enough to stick the neck of the bottle in there. This also works, by the way, with wine bottles—you can drill hole in the cork.

And you take the bottle, force it upside down in the hole, right in the soil. And there you go. Now that will very slowly drip a little bit of water each minute or two into the soil and keep it nice and moist.

This is ideal for watering plants when you’re on vacation or if you’re just away for few days. And when you come back your plants will be nice and hydrated, lush, and as green as ever.
