Pear trees can become damaged from harsh weather conditions. When they fall still attached to their roots, they cause a distracting focal point for your yard. Likewise, a pear tree's roots can disrupt other vegetation, plumbing or outside structures. Torn areas of the wood are perfect breeding grounds of a host of fungal infections that often infect pear trees. By removing the pear tree's roots, you prevent your healthy and cultivated trees from contracting a disease and improving the aesthetics of your landscape.
Dig around the pear tree's roots with a shovel. Wet the soil if it is hard. Make sure that you have a complete circle dug out to make lifting the remainder of the tree out of the hole easier.
Push hard on the pear tree to force it into falling down with some of the root system intact. Generally, some of the roots will break off in the soil and must be hand removed.
Dig about a foot or two from the root system. With your hands remove any of the dirt to expose the roots. Take a saw and cut up any of the remaining roots.
Saw any of the remaining roots. Use an back hoe for lifting up the cut portions of the roots.
Throw away or burn any tree root systems that have been infected with fungal diseases. For roots that have succumbed to natural conditions, use the wood as mulch or compost.
Remove any small portions of roots with tree stump remover. Chemicals and tree stump remover are formulated to cause wood to quickly decompose. Avoid burning your tree's roots.
