There are 100 native or wild species in the rose family, which grow around the world. Wild roses offer gorgeous color and require little if any maintenance. Because the plants are tough enough to make it with little help, they also are tough enough to present a daunting and physical task to someone trying to remove wild rose bushes.
Cut the stems of the wild rose bushes back severely-- to 2 to 3 feet if you plan to transplant the bushes. If you plan to discard the bushes, use the shears to cut them as close to the ground as possible. Wear gloves and long sleeves to avoid being pricked by thorns.
Put the shovel into the soil a couple of feet from the base of the rose bushes. The distance may vary: The goal is to dig around, not sever, the roots--particularly if the goal is transplanting the wild rose bush. Step on the shovel and add your weight to it, in order to have the shovel head completely penetrate the ground.
Create a trench, of sorts, by digging around the base of the rose bush in a circle. The goal is to remove and loosen enough soil so you can remove the wild rose bush without ripping out the roots.
Work the shovel under the bush. Use the shovel as leverage to pry the rose bush and its "root ball" up, creating more room to work the shovel deeper under the bush and roots.
Continue digging and prying until the wild rose bushes can be picked up and either transplanted or discarded.
