Hanging Round Garden Daybed - When vegetables that are growing in raised garden beds utilizing the Square Foot Gardening method, your beds will have to be sectioned off into one-foot sections called planting squares. A 4x4 foot garden bed, for instance, will have 16 planting squares (because there are 16 square feet in a 4x4 bed). Each planting square has an address used to identify the square.
While for addressing the methods change, one of the most straightforward would be to use letters for numbers and columns for rows, and also the square is identified by the mix of the two. Numbering starts in the upper left corner and goes left to right, top to bottom. I have yet to locate a garden bed that is commercially available for marking planting squares off with an included feature.
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 want to utilize the Square Foot Gardening approach but until this is available, for marking off squares, you'll need to devise your own procedure. The first step will be to compute the dimensions on the interior of the garden bed, which is width and the length which is actually useable for planting.
But when you join the boards in the corners, you lose several inches, therefore the interior dimensions of the garden bed are actually a couple of inches short of the advertised size. Inside my case, my beds have an interior measurement of 46.25 inches x 94 inches. I refer to these dimensions as Useable Span for the rest of the post.
