Square Foot Gardening Without Raised Bed - When vegetables that are growing in raised garden beds using the Square Foot Gardening approach, your beds will have to be sectioned off into one-foot sections called putting squares. Each putting square has an address used to identify the square.
While the options for addressing vary, among the most straightforward would be to make use of letters for numbers and columns for rows, and the square is identified by the mix of the two. Numbering beginnings in the upper left corner and proceeds left to right, top to bottom. For example, putting square A1 is the upper left-hand square (1st column, 1st row), while putting square C4 is the square in the 3rd column as well as the 4th row. I have yet to find a commercially available garden bed for marking off putting squares with an included attribute.
I wish somebody would develop a Square Foot Gardening grid which you can fit into a garden bed that is raised to mark off squares, but until this really is available, in case you wish to use the Square Foot Gardening method, for marking squares off you will need to devise your own strategy. Step one would be to calculate the dimensions on the inside of the garden bed, which will be the length and width that's really usable for planting.
But when you connect the boards at the corners, you lose a few inches, therefore 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 Span for the rest of the short article.
