The squash they used isn't crookneck or zucchini, but those work. I'll also be using muskmelons this year, as they do a better ground cover thing.
The old women used pine needles for mulch, so they didn't have much in the way of weeds coming up anyway.
I did come away with some of their pinto beans to use for seed. I've kept those going and will use those again this year.
