How to Remove a Snowball Bush Root System

Snowball bushes can become a nuisance in the landscape when they are injured or diseased, outgrow their growing site or become troublesome to maintain. Under optimal conditions, snowball bushes are spectacular specimens that put on a show of large flower clusters. But these shrubs are susceptible to aphid attack, which can disfigure their appearance. Removal of the plant and its root system can be accomplished with both mechanical and chemical control. A clean appearance and size control can alternatively be achieved by pruning the branches back every few years to 2 to 3 feet.

Spade
Axe or chainsaw (optional)
Herbicide (glyphosate)

Instructions

- 1
  Cut around the tree's root system deeply, using a spade, deep enough to accommodate the plant's root system. Use the spade to cut underneath the stump of the tree to remove a large extent of the roots. Roots will be more extensive in sandy soils and somewhat constricted in harder, clay soil. If your snowball bush is large and tree-like, an axe or chainsaw may make this process easier.
- 2
  Apply herbicide to freshly cut stump, focusing on where the bark joins the wood of the stump, as well as on any exposed tree roots. Use a brush to ensure complete coverage. It may be beneficial to cut the root before application to improve absorption, such as by drilling several holes or splitting it with a wedge. Chemicals should be applied within 24 hours of cutting down the plant.
- 3
  Cut off any sprouts that emerge from remaining roots, or spray with an herbicide containing glyphosate. Monitor the plant and remove sprouts continuously to maintain control.
