River Birch Roots Lifting Landscape: Cut ≤25%, Water After

Roots extend 1.5× branch spread. You can cut ≤25–30% of root area without killing the tree. Expect some foliage dieback on that side. Cut far from trunk. After cutting, water 1 inch weekly to stimulate new roots.

Alternative

Cover exposed roots with ≤3 inches sand + sod to redirect water. Less invasive.
