We all know how much space one zucchini plant can take up. Ive been growing mine vertically with a t-post and a jumprope for years. If you’ve been to even my beginners square foot gardening classes you know how it’s done. It also helps you to harvest zucchini at the proper stage by not letting it get too big. This is sandwiched next to 2 tomato plants, a cantaloupe plant, basil, parsley, potatoes and beans. Everything grows in the square foot garden while being really efficient.
