Skim off 2-4 inches of topsoil from your paths and add it to the planting area. The deeper your topsoil is in the beds, the better your crops will grow. Addition of organic materials such as compost raises the beds even more. Raised beds can be dug with a garden fork or shovel. Double dig your beds for best production with closely spaced crops.
Double digging involves removing the top layer of soil, so that the next layer can be loosened.
Double digging further improves drainage, nutrient availability and plant growth. For more information contact your local WSU Cooperative Extension Office .
