Sands & Soils FAQs
How much soil do I need to top-dress a 500 sq ft lawn to a depth of 1/4 inch?
Calculate volume by multiplying area by depth in feet: 500 sq ft x 0.0208 ft (1/4 inch) = 10.4 cubic feet, roughly 0.39 cubic yards. Buying 1 cubic yard gives you ample material and a margin for unevenness.
Can I mix sharp sand with compost for container plants?
Yes. Mixing 1 part horticultural sand with 2 parts multipurpose compost improves drainage for many container-grown plants, especially succulents and Mediterranean herbs. Avoid builder’s sand or contaminated sands that may carry salts or impurities.
Is loam better than topsoil for raised beds?
Loam is generally preferable because it has a balanced texture and holds nutrients while draining well. If you can source screened loam, it’s an excellent choice for raised beds. Topsoil works too, but ensure it’s free of large stones and weed seeds.
Should I use sand to fix a clay garden?
Adding sharp sand can improve drainage in clay soils, but it works best when mixed with organic matter and tilling over several seasons. Adding sand alone in the wrong proportions can create a concrete-like layer; aim for a balanced amendment strategy rather than a quick fix.
When is bulk soil more cost-effective than buying bags?
Bulk soil (sold by the cubic yard) becomes cost-effective for projects needing roughly 3 cubic yards or more. Bulk reduces per-unit cost and saves on packaging, but consider delivery placement and whether you can move the material to planting areas.
