Gardening With Raised Vegetable Beds - When growing vegetables in raised garden beds utilizing the Square Foot Gardening method, your beds will have to be sectioned off into one-foot segments called planting squares. Each planting square comes with an address used to identify the square.
While for addressing the methods change, one of the simplest would be to use letters for numbers and columns for rows, as well as the combination of the two identifies the square. Numbering beginnings in the upper left corner and goes left to right, top to bottom. I have yet to find a commercially available garden bed for marking off planting squares, with an included attribute.
I wish somebody would build a Square Foot Gardening grid that you can fit into a garden bed that is raised to mark off squares, in case you intend to use the Square Foot Gardening method but until this is available, for marking off squares, you'll need to devise your own procedure. Step one is to calculate the dimensions on the inside of the garden bed, which can be the length and width that is really usable for planting.
The 4x8 foot garden beds I bought, for example, are 4x8 feet from end to end. But when you join the boards in the corners, you lose a number of inches, hence the interior dimensions of the garden bed are really a few inches short of the advertised size. In my case, my beds have an interior dimension of 46.25 inches x 94 inches. I refer to these dimensions as Usable Length for the balance of this article.
