Corn Companion Planting?
I'm cutting back on the variety of things I'm growing this year due to the fact my main gardening plot is going to be taken over by corn this year. In my 8'x12' plot I'm planning on having four rows of corn 10 stalks long each, so it'll work out to a little over a foot between stalks and about 18 inches between rows.
And like I said, that will take over my main garden plot (going to build some boxes for potatoes, sweet potatoes, peppers, etc as well as growing other things in large containers to offset that some), but I'm thinking it would be nice to have something else growing in there between the stalks to help reclaim some of that space, although with the tight quarters it can't really be something that requires me to be going in there constantly to pick (so no sneaking tomatoes or peppers in there).
Would it be worth the effort to try three sister planting in conditions that cramped?
