Raised Bed Garden Pic - When growing vegetables in raised garden beds utilizing the Square Foot Gardening method, your beds should be sectioned off into one-foot sections called planting squares. A 4x4 foot garden bed, for example, will have 16 planting squares (because there are 16 square feet in a 4x4 bed). A 4x8 foot garden bed will have 32 planting squares. Each planting square has an address used to identify the square.
One of the simplest is to use letters for amounts and columns for rows while the options for addressing vary, along with the square is identified by the combination of the two. Numbering starts in the upper left corner and moves left to right, top to bottom. For instance, planting square A1 is the upper left-hand square (1st column, 1st row), while planting square C4 is the square in the 3rd column as well as the 4th row. I have yet to locate a garden bed that is commercially available for marking planting squares off with an included attribute.
I wish somebody would create a Square Foot Gardening grid which you can fit into a garden bed that is raised to mark off squares, should you'd like to use the Square Foot Gardening process but until this really is available, you will need to formulate your own personal system for marking off squares. The first step will be to calculate the dimensions on the interior of the garden bed, that is the length and width that is truly usable for planting.
The 4x8 foot garden beds I bought, for instance, are 4x8 feet from end to end. But when you join the planks in the corners, you lose several inches, so the interior dimensions of the garden bed are actually a few inches short of the advertised size. In my own instance, my beds have an interior dimension of 46.25 inches x 94 inches. I refer to these dimensions as Usable Length for the rest of the particular article.
