I decided to try a new method this year for preparing my garden beds called double-digging. The double-digging method requires removing the top 12 inches of soil so that you can loosen the soil below. According to the experts, there are several reasons for taking the time to do this; better drainage, aeration of the soil, and it helps facilitate root penetration.
There are three key tools required for this method; a garden spade, round point shovel, and a spading fork. I started this process out using a garden spade to edge the garden bed. I drove the spade deep down into the soil re-establishing a new edge around the perimeter of the bed.
