Pretty Raised Garden Beds - When vegetables that are growing in raised garden beds using the Square Foot Gardening method, your beds should be sectioned off into one-foot segments 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). A 4x8 foot garden bed will have 32 planting squares. Each planting square has an address used to recognize the square.
One of the simplest is to utilize letters for amounts and columns for rows while the means of addressing vary, and the square is identified by the mixture of the two. Numbering beginnings in the upper left corner and goes left to right, top to bottom. For example, planting square A1 is the upper left hand square (1st column, 1st row), while planting square C4 is the square in the 3rd column and also the 4th row. I've yet to find a commercially accessible garden bed with an included feature for marking off planting squares.
I wish somebody would create a Square Foot Gardening grid which you can fit into a garden bed that is raised to mark off squares, should you prefer to work with the Square Foot Gardening approach, but until this is accessible, you'll need to formulate your own personal method for marking squares off. The first step would be to compute the measurements on the inside of the garden bed, which is the length and width which is actually usable for planting.
However , when you join the planks in the corners, you lose a number of inches, so the interior measurements of the garden bed are really a few inches short of the advertised size. In my case, my beds have an interior measurement of 46.25 inches x 94 inches. I refer to these measurements as Useable Span for the remainder of the particular article.
