# Build a Raised Garden Bed for SC Red Clay Soil

> Columbia's red clay = Spartanburg's red clay. Use untreated 2×10 pine, hardware cloth bottom, 60/40 topsoil/compost mix. Materials at Lowe's Westgate Mall.

Spartanburg sits on the same Piedmont red clay that runs from Columbia through the Upstate. That clay is dense, poor-draining, and high in iron oxide — beautiful on a hillside, terrible for a vegetable bed. A raised bed solves all of that in a weekend.

**Materials (under $180 at Lowe’s Westgate)**

• Four 2×10×8 untreated pine boards (do NOT use pressure-treated for food crops)

• One roll of 1/2-inch hardware cloth (keeps voles and moles out of Spartanburg’s soft soil)

• 3-inch exterior deck screws

• Landscape fabric staples

• Soil fill: 60/40 topsoil to compost mix (roughly 16 cubic feet for a 4×8 bed)

**Why untreated pine** — Pressure-treated lumber leaches copper azole into the soil. For non-edible beds (flowers, ornamentals) it’s fine. For tomatoes, peppers, herbs, or anything that enters your kitchen, use untreated pine and accept the 6-8 year replacement cycle.

**Hardware cloth bottom** — This is the step most DIY guides skip. Spartanburg County soil is prime vole territory, especially within a mile of any wooded lot. Staple 1/2-inch hardware cloth to the underside of the frame before you place the bed. You will thank yourself next spring.

**Fill mix** — Do not dump pure compost in. Pure compost compacts, dries into a brick, and starves roots. Use 60% screened topsoil (Blue Ridge Log Cabins or any Spartanburg landscape supplier sells it by the scoop) and 40% composted pine bark or leaf compost. Water it in heavy the first week.
