Double Digging

This method of cultivation turns the soil over to a depth of 2 spits (about 250 to 500mm). The soil is dug and removed from a narrow trench and working backwards, the soil from the dug trench is turned into the first trench. This sequence is continued until the entire area has been dug over.

Fork over the base of the trench to aid root development and drainage. The incorporation of soil amendment material can be more easily undertaken whilst turning over the soil from one trench to another, between the first and second excavated spit.

Double digging can be a time consuming and tiring task, however, it provides an ideal preparation for the planting and establishment of shrubs and trees.

Even if the soil is of a good quality, forking and digging it over will still most likely be required to help in the production of a suitable tilth during the final ground preparation stage.
