I am putting in raised beds this year for vegetables, flowers, and herbs. How deep should the raised beds be?

Annual plants typically have root systems that reach about 12 to 18 inches. If your raised beds will be shallower than that, it's a good idea to till, or at least loosen, the soil underneath the raised bed to a depth of one foot. This encourages plants to form deep roots and helps provide good drainage.
