About this compost

Finished screened compost, fully broken down and ready to work into beds. The general purpose choice for building soil that holds water and feeds roots.

One of the easiest customer service experiences I've had in a long time! Mulch Mound made it so simple. After putting it off for a while, I looked at the weather and knew I needed to get to mulching ASAP before the rain came if I didn't want to wait another week. I put my orde...

One cubic yard of this compost covers about 324 square feet at a 1 inch depth, which is the right amount for topdressing an established lawn. If you're amending a bed and tilling in 2 to 3 inches, plan on roughly 100 to 160 square feet per cubic yard depending on how deep you go. Measure the actual bed or lawn area first, then match it to the depth you're using rather than guessing.

A yard is approximately 27 cubic feet. As a general guideline, one yard of material can cover an area of about 100-160 square feet at a 2-3 inch depth.

Compost pairs well with a topsoil blend when you're building out a new bed in Pittsburgh's clay, since the topsoil gives you bulk and the compost gives you biology. If you're mulching after amending, a shredded hardwood or double ground mulch on top holds moisture and keeps the compost from drying out before it can work into the clay below.

Mulch Mound Pro Tip

Pittsburgh's silty clay holds water differently than sandy soils, so when you till compost into a bed, do it when the clay is moist but not soaked, working wet clay creates compacted clumps that take a season to break down. Wait a day or two after rain. The goal is crumbly, not sticky, and you'll feel the difference in the tilth immediately when you dig into it with a shovel.

Mulch Mound Pro Tip

The most common mistake we see is piling compost on too thick thinking it'll feed the lawn faster. Finished compost works down over weeks, not days, and a layer over an inch on turf can smother grass or lock up nitrogen as it finishes breaking down. Thin and even beats thick and clumped every time, especially heading into Pittsburgh's shorter fall growing window before the Oct 10 frost.

Mulch Mound Pro Tip

Buying compost and topsoil together for a new bed build is usually more efficient than buying compost alone and trying to stretch it as your only soil volume. Use topsoil as your base fill and compost as the amendment layer worked into the top 6 inches, you'll use less compost overall and get better long term structure in that clay than trying to compost your way to a full bed depth.

Building Better Soil in Pittsburgh

Pittsburgh's silty clay compacts hard, especially on the slopes and postage stamp yards you find around the South Side and the North Hills, and compost is one of the few things that reliably opens it back up. In zone 6b, you've got a workable window in spring after the soil dries out around last frost near May 10, and again in fall before the ground firms up around the Oct 10 frost date. Compost worked into clay before either planting window gives roots somewhere to go instead of hitting a wall. On lawns, a thin topdressing helps offset the compaction that comes from Pittsburgh's hilly, foot-traffic-heavy yards.

What Finished Compost Is

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.

How Much to Apply

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.

When to Apply

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.

Answer

Will compost actually fix Pittsburgh's clay soil or do I need something else too?

Compost is the right tool for clay, it adds organic matter that helps break up compaction and improve drainage over time. For heavy clay we usually recommend working it in over a couple seasons rather than expecting one application to transform the bed. Tilling 2 to 3 inches in each spring and fall gets there faster than a single big dose.

Answer

How much compost do I need for a 1,000 square foot lawn?

At a 1 inch topdressing depth, one cubic yard covers about 324 square feet, so a 1,000 square foot lawn needs roughly 3 cubic yards. If you're doing a smaller bed at 2 to 3 inches instead, the coverage drops significantly, closer to 100 to 160 square feet per yard, so measure your actual depth before ordering.

Answer

Is spring or fall better for adding compost in Pittsburgh?

Both work, this material sells well in both seasons here. Spring compost, applied once the clay has dried out after last frost around May 10, gives beds a boost heading into the growing season. Fall application before the Oct 10 frost lets compost break down over winter and improve soil structure by spring planting time.

Answer

Where will the compost be dropped and do I need to be home?

We place the load at your driveway, curb, or another accessible spot you specify at checkout, and you don't need to be home for delivery as long as access is clear. Just make sure there's room for a truck to reach the drop point and that anything you want protected, like pavement, has a tarp down beforehand.

Answer

Should I get compost or topsoil for a new garden bed?

They do different jobs. Topsoil is your bulk fill material for building bed volume, while compost is the amendment that adds nutrients and improves structure. For a new bed in Pittsburgh's clay, most people use topsoil as the base and till compost into the top few inches rather than filling the whole bed with compost alone.
