Vertical gardening - it maximizes your harvest, makes the most of limited space, doesn't require lots of bending, and keeps your veggies away from pests and rot. This easy-to-assemble kit lets you grow vertically vining plants either against a wall, or as a free-standing unit using your own posts. Takes up just four square feet of growing space but produces more vegetation than a 24 square foot plot! Perfect for tomatoes, pole beans, cucumbers, or any vining plants.
I did this. My suggestion would be to add cardboard or something up the sides to hold water. My garden did SO WELL, but it dried out easily. Also, in the individual holes, I planted herbs, green peppers and zucchini. They did excellent also!! - Garden Ideas
