Drip Irrigation For Raised Garden Beds - When growing vegetables in raised garden beds utilizing the Square Foot Gardening approach, your beds will need to be sectioned off into one-foot segments called planting squares. Each planting square has an address used to recognize the square.
While for addressing the methods change, among the most straightforward is to utilize letters for numbers and columns for rows, as well as the square is identified by the combination of the two. Numbering starts in the upper left corner and goes left to right, top to bottom. For instance, planting square A1 is the upper left-hand square (1st column, 1st row), while planting square C4 is the square in the 3rd column as well as the 4th row. I've yet to locate a garden bed that is commercially available with an enclosed attribute for marking off planting squares.
I wish somebody would develop a Square Foot Gardening grid which you can insert into a raised garden bed to mark off squares, in case you prefer to utilize the Square Foot Gardening method but until this is available, for marking off squares you will need to formulate your own strategy. Step one will be to calculate the measurements on the interior of the garden bed, that is width and the length that is actually usable for planting.
The 4x8 foot garden beds I purchased, for example, are 4x8 feet from end to end. But when you connect the boards in the corners, you lose a few inches, hence the interior measurements of the garden bed are actually a few inches short of the advertised size. In my own case, 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 the article.
