- Rinse the bottles well with warm, soapy water, and strip off the plastic labels.
- Drill two to three small holes into the cap—1/8” holes tend to work well. If you don’t have a drill, place the cap on a hard surface and hammer a hole with a similarly sized nail. Screw the cap back on the bottle.
- Using a utility knife, carefully slice off the bottom inch or two of the bottle, leaving a nice, easy-to-fill wide-mouth opening (which doubles as a rain-catcher, if we’re lucky enough to see rain in July).
- Gently dig a hole next to the plant—try not to disturb the roots too much—and bury (cap side down) about a third of the bottle. If you can, angle the bottle’s cap toward the plant roots to ensure optimal moisture delivery.
- Secure the bottle by pressing soil firmly around it.
I love this super green idea! It's from The Grid magazine, out of West Philly. I am already collecting bottles so I can do this when we go on vacation this summer. I have some beautiful tomato and bell pepper plants I don't want to die off in this squelching heat.
This is a great idea. Thanks for sharing!
