Veggie Garden Bed Designs - When vegetables that are growing in raised garden beds utilizing the Square Foot Gardening method, your beds should be sectioned off into one-foot sections called putting squares. A 4x4 foot garden bed, for instance, will have 16 planting squares (because there are 16 square feet in a 4x4 bed). Each putting square has an address used to recognize the square.
While the options for addressing change, among the simplest would be to use letters for amounts and columns for rows, as well as the square is identified by the mixture of the two. Numbering starts in the upper left corner and moves left to right, top to bottom. I have yet to find a commercially available garden bed for marking off putting squares with an enclosed attribute.
I wish somebody would create a Square Foot Gardening grid which you can fit into a raised garden bed to mark off squares, should you prefer to use the Square Foot Gardening approach, but until that is available, for marking off squares, you'll need to devise your own personal procedure. Step one would be to figure out the measurements on the interior of the garden bed, that is width and the length that is truly useable for planting.
But when you connect the boards in the corners, you lose a few inches, or 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 Length for the balance of the particular article.
