Removing shrub roots is a process that depends on the quality of the soil and the tools used. Removing the shrub with a gardening tool is easier when the soil is loose. The project possibly requires the use of shovels, hoes and saws. Shrubs with more extensive root systems require chemical treatment.
Water the ground before moving
Removing shrub roots is easier when the soil is moist and loosened. Pull away smaller shrub roots by hand. Hold the root and pull away firmly for entrenched roots. Cut away the remaining root system with a tool.
Cut and dig with various tools
Cut and dig up larger roots from the ground using leverage from the handles of the tools. A branch lopper or root saw are good tools to use. Shovels, digging forks and grubbing hoes are other leverage tools to consider.
Search for and destroy remaining roots
Search for remaining roots to ensure all traces of the root system are gone. Throw away remaining roots. Smaller roots lead to more root extensive root growth. Digging the ground for more roots may be necessary if too many roots were pulled away from the surface. Gardeners can trace root paths by following the suckers and seedlings.
Use an herbicide, such as a glyphosate, to treat the area. If new roots grow, saturate completely with a nonselective herbicide. Monitor the area for the next few years and pull away new shrub roots as they emerge.
