Companion Planting Raised Garden Beds - When growing vegetables in raised garden beds using the Square Foot Gardening method, your beds should be sectioned off into one-foot sections called planting squares. Each planting square comes with an address used to recognize the square.
Among the most straightforward is to make use of letters for numbers and columns for rows while the options for addressing change, along with the square is identified by the combination of the two. Numbering beginnings in the upper left corner and goes left to right, top to bottom. For example, planting square A1 is the upper left hand square (1st column, 1st row), while planting square C4 is the square in the 3rd column and also the 4th row. I've yet to find a commercially accessible garden bed for marking planting squares off with an enclosed feature.
I wish somebody would develop a Square Foot Gardening grid which you can insert into a garden bed that is raised to mark off squares, in case you would like to use the Square Foot Gardening method but until that is accessible, for marking off squares, you'll need to devise your own method. The very first step would be to compute the measurements on the inside of the garden bed, that is the length and width that's actually useable for planting.
But when you join the boards at the corners, you lose a few inches, so the interior measurements of the garden bed are really a couple of inches short of the advertised size. In my own instance, my beds have an interior measurement of 46.25 inches x 94 inches. I refer to these measurements as Useable Span for the rest of this article.
