What Cedar Grove Composting supplies

Screened topsoil is the workhorse material for new lawns, raised beds and regrading work. Yards typically screen to ½" or ⅜" to pull out rocks, roots and clods, and many sell blended mixes that cut native soil with compost or sand to improve structure and drainage.

Ask which blend you are buying. Straight screened topsoil suits filling and levelling; a 50/50 or 70/30 soil-compost blend performs far better as a planting medium. Pure fill dirt is a different product entirely — unscreened, often clay-heavy, and meant for structural filling rather than growing.

Bulk mulch comes in hardwood, dyed, cedar, cypress and pine bark varieties. Bought loose by the yard it usually costs well under half the per-volume price of bagged mulch at a big-box store, which is why most repeat buyers switch to bulk.

Because Cedar Grove Composting carries several material lines, it is often possible to combine an order across products — soil, mulch and stone on one truck — rather than paying separate delivery charges to two or three different yards.

How much material you need

Topsoil is sold by the cubic yard. A cubic yard of topsoil weighs roughly 2,000–2,400 lbs depending on moisture, so a half-ton pickup safely carries about one yard.

As a rough guide: 1 yard covers about 100 sq ft at 3 in; 3 yards covers about 325 sq ft at 3 in; 10 yards covers about 1,080 sq ft at 3 in.

Have length, width and target depth ready when you phone. Yard staff convert those into cubic yards far more reliably than a generic online calculator, and they know how their own material settles.

Ordering and delivery

Ask about delivery minimums and trip charges up front — for smaller orders these often matter more to the final bill than the headline per-cubic yard price.

Check where the truck can actually dump. Tandem trucks need overhead clearance and firm ground, and most drivers will not reverse across a soft lawn or a new driveway. If access is tight, ask whether they run a smaller truck or can leave the load at the kerb.

Pricing for bulk material is rarely published in full, since it moves with stock and season. The business website may list current products, but a phone call will get you a firm delivered number faster.

Ratings and reputation

Of the 42 reviews on file, 15 are five-star (36%) and 3 are four-star. 22 reviews sit at one or two stars, and those are worth reading directly — complaints at material yards usually concern delivery timing or short loads rather than the product itself.

Among the suppliers we list across Washington, this rating places Cedar Grove Composting in the top 99%.

Across the 11 suppliers we list in Seattle, the average rating is 4.2.

Review volume matters as much as the score. A 2.8 drawn from 42 reviews is a reasonable sample for a local yard.

Hours and visiting the yard

Cedar Grove Composting is open 6 days a week, closed on Sunday. The yard opens as early as 7 AM and runs until 5 PM, early enough to load before a normal work day begins.

Saturday opening makes this a practical option for weekend projects — a real advantage, since plenty of bulk yards shut for the weekend and leave homeowners unable to collect material outside working hours.

Loading is weather-dependent whatever the posted hours say. Heavy rain turns yards to mud and makes wet material heavier and harder to spread, so call the same morning if conditions look poor.

Best time to buy in Washington

Demand for topsoil peaks from spring through early summer across Washington, when yards run their longest queues and hold firmest on price. Late summer and autumn typically bring shorter waits and more negotiating room, particularly on larger loads. If your project timing is flexible, buying outside the spring rush is the single easiest way to reduce the delivered cost.
