We have had a collection of EarthBoxes for over 10 years. Back in New York, we kept 15 of them on a deck raised 8 feet in the air-out our back door. The deer problem was so fierce there for a few years, that no fences deterred those deer from my lettuce, peas etc. When we enlarged our deck at the new Ohio house, we decided to forgo a railing around the deck, and stack our EarthBoxes around the edge, creating a cascade effect with some bricks, boards and blocks. For those who do not have large yards, this is a great way to garden. We use the EarthBoxes to create a kitchen garden-full of lettuce, radishes, green onions, chard, beets, herbs, etc. I can walk out the front doors, in my bare feet, and putter in my container garden. The tallest tier is almost as high as my waist, allowing me to garden without kneeling. The EarthBoxes are easy on water consumption, there is a reservoir on the bottom, and the water wicks up through the soil to the plants. You water the plants by pouring water down the tube in the corner, and in moderate heat, we only water once a week if we have not had a nice rainfall. It is very pleasant to sit in an Adirondack chair surrounded by the vegetables and flowers in the boxes. The lettuces and herbs are kept very clean in the elevated boxes.
I have planted nasturtiums on the outside edge of each tier of boxes, and anticipate a cascade of those hot colored blossoms, turning my deck into the Hanging Garden of Babylon-of a more modest size!
