Raised Bed Garden Corners - When growing vegetables in raised garden beds using the Square Foot Gardening method, your beds will have to 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). Each planting square comes with an address used to recognize the square.
Among the simplest is to utilize letters for numbers and columns for rows while the options for addressing change, and also the mix of the two identifies the square. Numbering starts in the upper left corner and moves left to right, top to bottom. I've yet to find a garden bed that is commercially available for marking off planting squares with an included feature.
I wish somebody would develop a Square Foot Gardening grid which you can insert into a raised garden bed to mark off squares, should you'd like to make use of the Square Foot Gardening process but until this really is available, for marking squares off, you'll need to devise your own personal system. The initial step is to calculate the measurements on the inside of the garden bed, which is width and the length that's truly usable for planting.
But when you connect the planks at the corners, you lose several inches, therefore the interior measurements of the garden bed are really a few inches short of the advertised size. In my instance, 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 this post.
