Managing Root Suckers on Bradford Pear Trees

Why Bradford Pears Produce Root Suckers

Bradford pear trees naturally develop surface roots that sprout suckers, especially when roots are exposed due to shallow planting or soil erosion. A 13-year-old tree in Pittsburgh with increasing suckers each year is exhibiting typical behavior for the species.

Effective Management Strategies

• Cover exposed roots with no more than 3 inches of soil. For lawns, a sand-topsoil mix works well—grass grows through it quickly.
• Do not chop out surface roots. This damages the tree, reduces foliage, and often stimulates more sucker growth.
• Cut suckers as they appear. While they cannot be permanently eliminated, covering roots reduces their number.

What Not to Do

Removing large surface roots stresses the tree and can lead to decline. Suckers are a symptom of root exposure, not a disease, so address the root cause rather than repeatedly cutting shoots.

Key Takeaway

Cover exposed roots with a shallow layer of soil to suppress suckers and maintain tree health. Accept that some sucker management will be ongoing.
