How deep should a raised garden bed be?
A raised bed should be a minimum of 6-12 inches deep. This ensures there is enough room for your plants to develop a good, deep root system, but you can make the raised bed as deep as you would like. If your bed is not 12 inches deep, you could dig out a bit of the ground before adding the dirt to make it deeper. Most herbs and veggies like a good soak, but they don’t want their roots sitting in water too long. So if your raised bed does have an enclosed bottom, make sure to check on the draining situation. You may have to drill drainage holes every 6 inches or so to allow water to pass through.
