Building a Dry-Stack Stone Raised Bed: Footing Prep Is Everything

You want a 3' × 10', 18"-high dry-stacked stone raised bed on existing lawn in Kentucky. There are a few tree roots in the cleared area. The question: level the dirt and start stacking, or invest in a proper base?

Do not skip the footing. Even a small wall fails without it. Here's the right way:

Footing Excavation & Base

• Dig 6" below finished grade, 2 feet wider than the wall (12" each side).
• Fill with 2–3" of compacted gravel, road base, or crusher run.
• Compact thoroughly with a hand tamper. Check for level in every direction.

Stone Placement

• Lay stones in a running bond pattern (1-over-2, 2-over-1).
• Integrate larger "through-stones" that span the full wall width—distribute them throughout, not just at the bottom.
• Check level and plumb constantly with a long level and string line.
• No batter needed for an 18" freestanding bed—keep it vertical.

Tree Roots

Work around significant roots. Don't sever major ones; adjust stone placement instead. The compacted gravel base bridges minor roots fine.

Prep is 80% of the result. Rush the footing, and the wall will shift within a year. Take your time—it's a weekend project that lasts decades.
