How? Two ways:
- The GardenDesk shows how you can convert the bottles to slow drippers - great if you're like me and forget to water your plants some nights!
- Simple, Green, Frugal Co-Op explains how plastic bottles can be used to extend the life of your garden during the early season.
While I can't speak as to the long-term implications of leaving the plastic in your garden, it's a temporary solution to a problem.
