The trick is in the planning. You want to be able to rotate your food families, so that a single box doesn't become a haven for insect pests or other messies. You don't want to mix lots of vegetable families inside one box or it makes rotating hard.
Also, and this is important - be careful with summer vegetables to plant veggies of similar height together. Otherwise, you'll have shading problems come up as the taller plants grow. Be careful to plant shorter types of flowers. We have super rich soil in our boxes and my flowers shot up like Paul Bunyans!
One more thing: If you live in the South, don't do everything the way Mel Bartholomew says to in his book. He says you can plant tomatoes a foot apart. Maybe if you live up north you can, but down here our plants grow tall fast and our growing season is longer. Our tomatoes got wilt.
I'm in the process of trying to plan my boxes so that I can rotate vegetable families. I think it will take a lot of boxes if we're going to have enough for canning. That's a ton of wood that we can't afford, so we may just outline a 4 foot by 8 foot patch of ground and lay string across to make grids.
The best thing about square foot gardening is that weeding is no big deal.
