Small Garden Bed Trees - When vegetables that are growing in raised garden beds using the Square Foot Gardening method, your beds will need to be sectioned off into one-foot segments 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). Each putting square has an address used to identify the square.
While the methods for addressing vary, among the simplest would be to make use of letters for numbers and columns for rows, and the square is identified by the combination of the two. Numbering beginnings in the upper left corner and moves left to right, top to bottom. I have yet to locate a commercially available garden bed with an included attribute for marking putting squares off.
I wish somebody would develop a Square Foot Gardening grid which you can insert into a garden bed that is raised to mark off squares, but until this is available, if you prefer to work with the Square Foot Gardening approach, you will need to devise your own method for marking squares off. Step one would be to calculate the dimensions on the interior of the garden bed, which will be width and the length that is actually useable for planting.
But when you connect the planks at the corners, you lose a few inches, or so the interior dimensions 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 dimensions as Usable Length for the rest of this article.
