Safe Wood For Garden Beds - When vegetables that are growing in raised garden beds utilizing the Square Foot Gardening approach, your beds will have to be sectioned off into one-foot segments called putting squares. Each putting square comes with an address used to identify the square.
While the options for addressing change, one of the simplest is to make use of letters for amounts and columns for rows, and the square is identified by the mix of the two. Numbering starts in the upper left corner and proceeds 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 and the 4th row. I've yet to find a commercially available garden bed for marking putting squares off with an enclosed attribute.
I wish somebody would create a Square Foot Gardening grid that you can insert into a garden bed that is raised to mark off squares, if you would like to work with the Square Foot Gardening approach, but until this really is available, for marking off squares, you'll need to devise your own method. The initial step is to figure out the dimensions on the interior of the garden bed, which will be the length and width that's really useable for planting.
The 4x8 foot garden beds I bought, for example, are 4x8 feet from end to end. However , when you join the boards in the corners, you lose a number of inches, hence the interior dimensions of the garden bed are actually a couple of inches short of the advertised size. Inside my case, my beds have an interior dimension of 46.25 inches x 94 inches. I refer to these dimensions as Usable Length for the remainder of this post.
