smoke bush/tree

Question

The roots on my smoke bush have pushed upward. Should I keep covering with dirt when they surface again?

Answer 1

Is there a reason for the root exposure? Heavy rain, flooding, soil erosion?

The root system of a Smoke Tree is quite fibrous. You can add soil with some organic amendments to cover exposed roots. Apply 3 to 4 inches of hardwood mulch to help hold soil in place. Avoid the mulch touching the trunk of the tree.
