Double digging is practically the same as single-spit digging but, when the trench is opened, the subsoil or second spit of soil should be thoroughly broken up with the fork, and as each section of under-soil is revealed it, too, should be forked over. In this way the soil is worked to a depth of 2 ft.

Double digging is much better than single-spit digging, since the soil is better æerated, water can pass through more easily, and the roots of the plants can penetrate more deeply in search of food. This method is shown in Fig. 5.
