|El B has three sisters|
What are your thoughts on the Three Sisters?For those unfamiliar with the reference, Three Sisters Agriculture is the practice of planting corn, beans, and squash together. The corn grows up, the beans climb the corn while fixing nitrogen in the soil for the corn, the squash spreads over the ground and smothers the weeds. This is actually a very old method of planting, practiced by a number of New World cultures. Some peoples added sunflowers, giving Four Sisters, while others buried a fish beneath the corn, but the idea is the same: the plants each provide something for the others.
When I began experimenting heavily with companion planting this was one configuration I passed over, mostly because I'm not fond of corn in the garden and I don't generally eat squash. We tried it in one 4'x10' bed this year because a) while the lovely and gracious Rogue is fond of corn, she is not fond of weeding, and b) I can always give the squash to the old ladies at church. Though just in case something bad happened* I planted green beans in another bed as well. I also used three very different kinds of squash** to see if one performed better than the others.
Pictured above is the experiment thus far. I waited until the corn was 6" high before planting the companions and they are just now coming up. Because the ground is not yet covered, I have a bit of weeding to do, including a bunch of little maple seedlings, but it's nothing too troublesome as the good plants are all organized into obvious groups at present. Based on the speed of my pumpkins' growth, I estimate that within 3 weeks this whole bed will be covered by squash leaves.
So with that as background, my thoughts: I am inclined to favor any practice that both sounds good in theory and has lasted a long time. I'm also confident that I'll be able to find a way to make squash edible, at least by someone. Still, I can boast no actual experience until the harvest comes in, and am therefore loth to recommend any more than that you try it.
