Make your own “vertical veggie garden” with some gutter material and an exterior wall you’re not doing anything with anyway!
The Hack: Use a wall and some gutter material to make a vertical garden where no garden has dared to cling!
“… The idea is essential this: Why not put rain gutters in rows along the wood siding on the sunny side of the house. It might look weird, but that was where all the heat, sun and protection from damage is best. I talked to my husband, Pete, about it and he agreed it was worth a try.
We went to Home Depot and selected some “attractive” brown plastic gutters along with all the required parts so that we could mount them in one long row. (The total length or a row would be about 20 feet). Pete drilled some very small holes in the bottom of the gutters to let excess water drain out after he mounted them on the siding. …”
While this can be a convenient way of making use of unused space, there is the issue of the space needed for the plant’s root systems. Since you are using a six inch by perhaps twenty-four inch space per plant, minus the intermingling of the root systems with their neighbors, the size of your plants will probably be smaller. Looking at the root development of lettuce, for instance, you will see that the tap root in regular soil goes down beyond three feet!(Click on illustration for better picture and link to text). This illustration also shows why companion plants nearby also help each other owing to the fact that the root systems would intermingle. It also raises the question does square foot gardening really make sense? The confining nature of square foot gardens would inhibit the root systems, and the nutritional needs of the plants as well as their sunlight requirements could make a strong argument for more widely spaced plants that compliment each other (larger sun-loving plants giving shade to nearby lower growing plants that are harvested more frequently, such as lettuce grown on the north side of pole beans, etc.. Succession planting could still easily take place with faster growing crops, and the plants themselves may prove more nutritious with less need of fertilization since the plants would be drawing their nutrition from a wider area.
