The soil mixture must consist of 1/3 part compost, 1/3 part peat moss and 1/3 coarse vermiculite
Before filling the box with soil, place a sheet of weed mat at the bottom. This will prevent weeds from growing. A suggested soil reciped is 1/3 coarse grade vermiculite, 1/3 sphagnum peat moss, and 1/3 blended compost. There are many different forms of compost like worm castings, green waste, or manure. Next, place a grid on top of the box. This will evenly divide your square box into equal smaller squares. Placing the grid on top is the key in the difference between square foot gardening and gardening with raised beds.
