Pvc Pipe Raised Garden Beds - 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 sections called putting squares. A 4x8 foot garden bed will have 32 planting squares. Each putting square has an address used to spot the square.
While the methods for addressing vary, among the simplest would be to use letters for columns and numbers for rows, and also the square is identified by the mixture of the two. Numbering starts in the upper left corner and proceeds left to right, top to bottom. I have yet to locate a garden bed that is commercially available with an enclosed attribute for marking off putting squares.
I wish somebody would develop a Square Foot Gardening grid that you can add into a garden bed that is raised to mark off squares, but until that is available, should you intend to work with the Square Foot Gardening approach, you'll need to devise your own strategy for marking off squares. Step one is to compute the dimensions on the interior of the garden bed, that is width and the length that's really usable for planting.
The 4x8 foot garden beds I purchased, for example, are 4x8 feet from end to end. But when you join the boards at the corners, you lose a number of inches, hence the interior dimensions 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 dimensions as Useable Span for the rest of this post.
