I am planning my garden now and was wondering what plants are incompatible with others and what ones work best with each other. I have about a 40x40 area to plant. I know I want sweet corn, tomatoes, green beans, pumpkins, cucumbers, lettuce, cabbage, asparagus, brocoli, bell peppers, and maybe a couple more things. . . . . .oh carrots too. Anyway thanks a lot!
