Raised Beds Around Trees: How Much Soil Is Safe?

Building a raised bed 24–32 inches deep around a red maple: safe for mature trees (key roots beyond dripline), fatal for young trees (surface roots smothered).

Critical Rule

Never let added soil touch the trunk. Build a retaining wall near the trunk, allowing for future growth, to keep soil away.

Tree size determines feasibility. Protect the root flare.
