Elevated Garden Bed On Wheels - When growing vegetables in raised garden beds using the Square Foot Gardening approach, your beds will have to be sectioned off into one-foot segments 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). Each putting square comes with an address used to recognize the square.
While for addressing the methods change, one of the most straightforward is to use letters for amounts and columns for rows, along with the mixture of the two identifies the square. Numbering beginnings in the upper left corner and goes left to right, top to bottom. For example, putting square A1 is the upper left hand square (1st column, 1st row), while putting square C4 is the square in the 3rd column as well as the 4th row. I've yet to find a commercially available garden bed with an included feature for marking putting squares off.
I wish somebody would develop a Square Foot Gardening grid that you can insert into a garden bed that is raised to mark off squares, should you prefer to utilize the Square Foot Gardening approach but until this is available, for marking squares off you will need to formulate your own method. The first step would be to compute the measurements on the interior of the garden bed, that is width and the length that is actually usable for planting.
But when you join the boards at the corners, you lose a few inches, therefore the interior measurements of the garden bed are actually a few inches short of the advertised size. Within my instance, my beds have an interior measurement of 46.25 inches x 94 inches. I refer to these measurements as Usable Span for the remainder of the article.
