soil content - the soil that is generally used is mostly manure, compost and soil mixtures instead of ground soil; appearance - raised beds generally make very decorative gardens because the gardener enjoys maintaining them.
The 4x8 foot garden beds I bought, for instance, are 4x8 feet from end to end. But when you connect the boards at the corners, you lose a few inches, so the interior dimensions of the garden bed are actually a few inches short of the advertised size. In 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 article.
Total number of anchors: Add the results of Step 2, and multiply by 2. In my example, (7+3) * 2 = 20 anchors.
Numbering starts in the upper left corner and moves left to right, top to bottom. For example, planting square A1 is the upper left-hand square (1st column, 1st row), while planting square C4 is the square in the 3rd column and the 4th row. I have yet to find a commercially available garden bed with an included feature for marking off planting squares.
