Managing Surface Roots on a Raywood Ash

Your 35-foot Raywood ash has many surface roots spreading several feet. You want to know if you can remove them without harming the tree.

Do Not Cut Surface Roots

Removing surface roots—especially large ones—can destabilize the tree, invite decay, and cause decline or death. The risk increases with the size and number of roots cut.

Safe Alternative: Topdressing with Sand

• Spread 2–3 inches of coarse sand over the exposed roots.
• Keep sand at least 12 inches away from the trunk (root collar must stay exposed).
• Sand improves aeration and drainage better than soil, reducing further surface rooting.
• You can overseed grass into the sand or use it as a mulch base.

Why Roots Surface

• Compacted, heavy clay or shallow soils force roots upward for oxygen.
• Frequent shallow watering encourages surface roots.
• Raywood ash is naturally prone to surface rooting.

Long-Term Management

• Water deeply and infrequently to encourage deeper rooting.
• Avoid grade changes or compaction over the root zone.
• Mulch rings (not volcanoes) protect roots and reduce mowing damage.

Bottom Line

Cover the roots with sand—don’t cut them. It’s the safest way to level the lawn and protect your tree’s health.
