Due to the rigors of finishing our book The Urban Homesteader due out from Process Media next spring we were late getting around to planting our parkway vegetable garden. To review, the parkway is that space between the sidewalk and the street that belongs to the city but is the responsibility of the homeowner to maintain. The city, of course, wants us all to plant a lawn so that fat people can easily plop out of their Escalades unimpeded. We decided to grow food instead and despite the presence of many building inspectors reviewing our expensive foundation work nobody seems to care about the two large raised beds we installed. In fact one of our neighbors has planted her own parkway vegetable garden just down the street.
Since it was so late (July) we decided to cultivate heat tolerant vegetables and upped the ante by planting the Native American three sisters–corn, beans and squash. The three sisters are textbook permaculture, the idea being that the beans nitrogenate the soil and climb up the corn while the squash provides mulch. All plants are useful and you end up with an interdependent, self-sustaining beneficial feedback loop. Some people add a fourth sister, Rocky Mountain bee plant (Cleome serrulata) which attracts pollinating insects for the corn and squash.
We added a drip irrigation system on a timer (more on that in a later post) which has seemed to keep the plants healthier by preventing watering mishaps due to those flaky hung-over mornings. We planted corn seeds from the Not a Cornfield project, a variety of squash called Cucuzzi, and two beans from seeds we saved from last season (the tasty Borlotto Lingua di Fuoco and attractive but not so tasty scarlet runner bean).
