Raised Bed Depth and Soil Prep for Container‑Style Gardens

Minimum Depth

8 inches (railroad ties = ~6–7" each; two stacked = 12–14" — ideal).

Prep Steps

1. Turn existing soil.
2. Cover with 2" newspaper — suppresses weeds, adds carbon as it decays.
3. Add topsoil + organic amendments: peat, compost, manure, grass clippings, shredded leaves.

Benefits

Better drainage, moisture retention, root development, and long‑term fertility.
