Organic Gardening Raised Bed Materials - 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. A 4x4 foot garden bed, for instance, 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 spot the square.
While the methods for addressing vary, one of the simplest would be to use letters for columns and amounts for rows, as well as the square is identified by the mix of the two. Numbering beginnings in the upper left corner and moves left to right, top to bottom. I've yet to find a garden bed that is commercially accessible with an included attribute for marking off putting squares.
I wish somebody would develop a Square Foot Gardening grid that you can insert into a raised garden bed to mark off squares, should you'd like to utilize the Square Foot Gardening method but until that is accessible, for marking off squares you'll need to devise your own personal procedure. The first step will be to calculate the measurements on the inside of the garden bed, which will be width and the length that's actually usable for planting.
But when you connect the boards at the corners, you lose several inches, hence the interior measurements of the garden bed are actually a few inches short of the advertised size. In my instance, my beds have an interior dimension of 46.25 inches x 94 inches. I refer to these measurements as Usable Span for the rest of the article.
