Pennsylvania farmer Blake Whisenant developed this easy-to-use, easy-to-grow system capable of growing veggies in a small, self contained garden box, the Earthbox. Marketing the box since 1994, Whisenant's idea has been adapted by handy gardeners for their special circumstances.
According to Leigh Spann, News Channel 8, Tampa, FL, a water reservoir at the bottom of the box keeps the soil damp. There is no watering from the top so there is less evaporation.
If you are getting anxious to get your plants outdoors, but the weather isn't cooperating, plant them in the box to give them a headstart on the growing season.
If you have no area for gardening, but want fresh vegetables out your kitchen door, the Earthbox could be the answer for you.
