Our local Garden Guy, Dave Owens (he has a website) has built an organic garden on part of a parking lot at the Channel 3 studio here in Phoenix. He recommends planting flowers and veggies together for the benefits of both in terms of warding off bad insects and inviting good insects. Gardening can be a challenge here in the low desert but he has a beautiful, bountiful garden there. I always plant veggies and flowers together, my whole front yard is trees, shrubs, veggies and flowers, much nicer than mowing grass, lol Pat Pat
