Colonial Williamsburg Garden Images Bedding - When growing vegetables in raised garden beds utilizing the Square Foot Gardening approach, your beds will need to be sectioned off into one-foot sections called putting 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 putting square has an address used to recognize the square.
One of the most straightforward is to make use of letters for numbers and columns for rows while for addressing the methods vary, and also the square is identified by the combination of the two. Numbering starts in the upper left corner and proceeds left to right, top to bottom. As an 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 and the 4th row. I've yet to locate a garden bed that is commercially available with an enclosed feature for marking putting squares off.
I wish somebody would build 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 approach but until this really is available, for marking squares off you will need to devise your own procedure. Step one is to compute the measurements on the inside of the garden bed, which will be width and the length that's in fact useable for planting.
But when you connect the planks at the corners, you lose a few inches, or so the interior measurements of the garden bed are really a few inches short of the advertised size. In my own case, my beds have an interior dimension of 46.25 inches x 94 inches. I refer to these measurements as Useable Length for the rest of the informative article.
