Screened Topsoil

Screened topsoil starts as ordinary bulk topsoil, pulled from a stockpile or excavation source, then run through a vibrating or rotating mesh screen. The screen size, usually stated as 3/8 in, 1/2 in, or 3/4 in, sets the largest particle that passes through. Anything bigger, rocks, root balls, construction debris, dense clay clumps, gets kicked out. A 3/8 in screen produces a finer, more uniform product suited to seedbeds and topdressing. A 3/4 in screen still removes the problem material but leaves a coarser texture that is fine for general fill-and-plant work and often costs less. Screening does not change the chemistry or fertility of the soil, only the particle size distribution, so two loads from different sources can look and drain differently even at the same mesh size. This is why screened topsoil is a decision about grade and use, not a single standardized product, and why it is worth asking your supplier what screen size they run before ordering for a fine finish job.

Screened topsoil performs best when the surface underneath is loosened, not left compacted. For lawns, till or scarify the top 2 to 3 in of existing subsoil before spreading topsoil, so roots and water can cross the boundary instead of stalling at a hard interface. Grade for drainage first, sloping away from structures, then spread topsoil in an even layer and rake it level rather than dumping and smoothing piles, which leaves inconsistent depth. Water it in after spreading to settle air pockets, and expect 5 to 10 percent settling over the first year as it weathers, more if the soil leans clay-heavy. If you are seeding, a light compaction pass with a roller after raking improves seed to soil contact without overcompacting. For topdressing an existing lawn, spread thin, 2 in or less, and work it into the turf with a rake or drag mat so it does not smother grass blades.

Compared with unscreened topsoil. Unscreened topsoil keeps the rocks, roots, and clumps that screening removes, and costs less per yard. It works fine for bulk fill, rough grading, or filling low areas under a lawn where nobody will dig by hand. Screened topsoil earns its price where a fine, rock-free surface actually matters, seedbeds, topdressing, and garden beds.

Compared with compost / garden soil blend. Compost is a decomposed organic amendment, not a structural soil, and is meant to be mixed into existing ground rather than used alone. Screened topsoil supplies the bulk volume and workable texture, but often needs compost mixed in to raise fertility for planting, especially in vegetable beds and raised beds.

How much screened topsoil do I need. Coverage depends entirely on depth. One cubic yard covers about 324 sq ft at 1 in, 162 sq ft at 2 in, 108 sq ft at 3 in, 81 sq ft at 4 in, and 54 sq ft at 6 in. Multiply your square footage by the depth in feet to get cubic yards, and round up slightly to cover settling, which typically runs 5 to 10 percent in the first year.

How it is sold and delivered. Screened topsoil is sold by the cubic yard and delivered in bulk, typically dumped as a pile at your driveway or job site rather than bagged. Larger orders may require a delivery window for scheduling the truck. Because weight per yard swings from about 2,000 to 2,700 lb depending on moisture, order by volume for your coverage area, not by weight.
