If you have shrubs that you want to remove, here’s how to get the roots out without hours of digging and chopping.
Use leverage. Start by digging around the base of the shrub and cutting all the roots you can get at. Then lay scraps of plywood on each side of the shrub. Set a jack stand or concrete blocks on one side and set up your jack on the other. Lay a beam across them and tie the root to the beam with a chain. You’ll apply hundreds of pounds of pulling force, so both the beam and the chain must be strong. Use a 6-ft. 4x6 or 6x6 for the beam and a chain for towing cars. Raise the jack, stopping to cut the roots as they become exposed. If you max out the height of your jack before all the roots are free, add a few blocks to increase the beam height.
Before cutting the roots, reduce tension on the chain to prevent injuries from recoil. Wear eye protection.
