How deep should I make vegetable bed?
I m in the process of making a bed for vegetables..tomatoes, zucchini, running beans and hopefully okra. How deep should it be? My soil is hard packed clay and it s so hard to dig! I ve dug down and loosened about 4 inches down and I will add 6inches of triple mix on top...(it will have a retaining wall for that). Is that enough?
