Plastic Raised Garden Beds On Legs - When vegetables that are growing in raised garden beds utilizing the Square Foot Gardening approach, your beds will need to be sectioned off into one-foot segments called putting squares. A 4x8 foot garden bed will have 32 planting squares. Each putting square comes with an address used to spot the square.
While the means of addressing vary, among the simplest is to utilize letters for amounts and columns for rows, and also the square is identified by the mixture of the two. Numbering starts in the upper left corner and goes left to right, top to bottom. For instance, 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 for marking putting squares off with an included feature.
I wish somebody would develop a Square Foot Gardening grid that you can add into a raised garden bed to mark off squares, should you'd like to use the Square Foot Gardening approach but until this really is available, for marking off squares you will need to formulate your own personal method. Step one would be to figure out the measurements on the inside of the garden bed, which is the length and width that's in fact useable for planting.
But when you connect the boards at the corners, you lose a few inches, so the interior measurements of the garden bed are actually a few inches short of the advertised size. In my own instance, my beds have an interior dimension of 46.25 inches x 94 inches. I refer to these measurements as Useable Span for the rest of this post.
