If you've ever flown into or out of the Lindbergh terminal at the Minneapolis-St. Paul International Airport during the summertime, you've probably noticed very large pots of (usually) petunias hanging from just about every lamp post bordering the entrance and exit routes. Every time I drive past them, I'm always struck by how thick the blooms are, as you can barely see any foliage. This is even more surprising on a hot June day when everything else is looking a little wilt-y. Of course the secret of the MSP petunias is a drip irrigation system. (You can see the little tubes running into each of the pots.) I've imagined--someday--having such a system myself so I wouldn't have to worry about my blossoms during those frequent summertime 3-day weekends. Someday, it seems, has arrived, and it's super easy and free--thanks to my recycle bin.
The 'system' is super simple. All we have to do is grab some 2-liter plastic bottles, punch 2 holes into the sides and 2 into the bottom, and plant said bottles next to our plants. Fill them with water and our plants will get that slow watering they prefer. For more information about the project, visit Fine Craft Guild.
