Raised bed soil blend
Be the first to rate it
Topsoil, organic matter and coarse sand in equal parts, or a compost-rich alternative, for filling raised beds.
What You’ll Need
- Topsoil: equal parts
- Organic matter (well-rotted manure, compost, or peat): equal parts
- Coarse sand: equal parts
- Alternative mix: ~70% topsoil and ~30% compost
Equipment
- mixing bowl
Directions
- Clear off any grass sod and loosen the existing soil with a rototiller or spade.
- Spread a few inches of the soil mix over the top and work it into the soil underneath.
- Keep adding mix and working it in until the bed is full; blending it in prevents layers that block water and roots.
- Level the surface so the soil slopes slightly from the center down toward the edges and away from buildings.
- Spread mulch around the plants to hold in moisture and hold back weeds.
Notes
Make sure topsoil is free of soil-borne plant disease and contaminants such as lead or pesticides, and that compost is mature and not too salty.
Safety: Wear gloves with manure and compost and wash hands after (especially before eating). Use only well-rotted manure around food crops. Have soil tested for lead if it’s from an unknown source.
