Soil Depth for Plants

Q: Is it better to do 12″ high or 24″ raised garden beds for my plants. What are the advantage and disadvantages?

A: It depends on what you are planning on growing.  Smaller plants will do great in 12″ of soil; salad greens, strawberries, herbs, etc.  For the larger plants like tomatoes and melons you should do beds that are at least 18″ deep, and 24″ would be great.  If you are placing them in an area where the soil underneath is good quality soil that the plant can grow down into the garden beds can be a little shorter.  Having enough soil area for plants is more important than we think, and will make a big difference on the health and yield of your plants.
