Wonderful experience! They put the mulch exactly where we wanted. This mulch spread very easily and didn’t have the usual “mulch smell.” We will definitely use again!

One cubic yard of our compost covers about 324 square feet at a 1 inch depth, which is right for lawn top dressing. For bed prep, where 2 to 3 inches gets tilled in, plan on one yard covering roughly 110 to 160 square feet. Measure your lawn or bed square footage first, then work backward from the depth you need.

Placing an order online was so easy. Delivery was on time. When the driver realized we had a newly poured driveway they erred on the side of caution and opted not ti drive in it. The company even sent me a message explaining that call. Would recommend!
Great service. We ordered topsoil from Mulch Mound and the best experience. Thank you so much!
Compost pairs naturally with a bark or wood mulch top layer once it is worked into beds, since the compost feeds the soil and the mulch holds moisture and blocks weeds. For lawns, a light compost top dress followed by overseeding gets you further than seed alone in Kennewick's dry summer stretch. If you are building new beds from scratch, we often see people order compost and a soil blend together.
Service area
In Kennewick's silt loam, resist the urge to pile compost on thick thinking it will do more good. More than 3 inches tilled into a bed can actually lock up nitrogen temporarily as soil microbes work through the extra organic material. Stick to 1 inch for lawn top dressing and 2 to 3 inches tilled into beds, then let the existing soil biology take it from there instead of overcorrecting.
Fall application timing matters here. With first frost landing around October 26, get compost worked into beds by early October so it has time to integrate into the silt loam before the ground cools and biological activity slows. Spring applications should wait until after April 5's last frost date, giving the soil a chance to warm before you disturb it and add fresh organic matter.
If you are amending several beds across a property, one bulk cubic yard delivery is more efficient than buying compost in bags trip after trip, and it lets you save leftover material properly under a tarp for a second application later in the season. Pairing compost with a topsoil blend on new beds stretches your material further than compost alone on Kennewick's naturally lean base soil.
Silt loam is the base soil across most of Kennewick, and it drains fine but tends to compact and lose organic content, especially with our low rainfall and hot dry summers. Compost worked into that soil profile improves water retention and feeds the microbial life that silt loam alone does not sustain. Wine Country's vineyards know this trick well, building soil rather than fighting it. Whether you are prepping a new bed near the Blue Bridge greenbelt or refreshing an established lawn, compost is the fix for tired, mineral-heavy dirt.
Finished compost is organic matter that has fully broken down into a dark, crumbly material with an earthy smell. It feeds soil life, improves structure, and helps beds hold water without staying soggy.
Work 1 to 2 inches into new beds, or topdress lawns with a quarter to half inch and rake it in. More is not better. Too thick a layer can smother roots instead of feeding them.
Spring and fall are both good windows. Spring applications feed the growing season ahead, and fall applications break down over winter so beds are ready at first thaw.
