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 cubic yard covers about 324 square feet at a 1 inch depth, which is right for topdressing an established lawn. For beds getting tilled in at 2 to 3 inches, figure closer to 110 to 160 square feet per cubic yard, so measure your bed square footage first and work backward from there.

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.

First time going with this company for mulch and it was an efficient process from start to finish. Website was easy—I told them exactly where I wanted the mulch put on my driveway, and it was delivered perfectly when I got home from work the next day. Best deal around when I compared it to competitors and I will definitely be becoming back.

Complete Your Outdoor Project

Compost pairs well with a topsoil blend if you're building up a new bed from scratch on our clay base, or with mulch layered on top after tilling to hold moisture and slow weeds. If you're overseeding a lawn this fall or spring, a thin compost topdress ahead of seed gives new grass something better than clay to root into.

Mulch Mound Pro Tip

On St. Louis clay, do not till compost in when the ground is wet, you'll just create dense clumps that don't break down evenly. Wait for a dry stretch, especially in spring after the clay drains, or in fall before the first frost around October 25 locks things up. A dry-enough test is simple, if a handful of soil crumbles instead of smearing, you're good to till.

Mulch Mound Pro Tip

The most common mistake we see is piling compost on too thick, thinking more equals better results. It doesn't, excess compost can actually lock up nitrogen and other nutrients as it keeps breaking down in place. Stick to 1 inch topdressed on lawns and 2 to 3 inches tilled into beds, and reapply next season rather than overloading now.

Mulch Mound Pro Tip

If you're building new beds from scratch, don't buy all compost, blend it with topsoil so you're not paying compost pricing to fill volume you don't need structurally. Compost is for feeding and structuring existing soil, topsoil is for bulk fill. Use compost where the clay already is, and save it for the top few inches where roots actually live.

Building Better Soil in St. Louis

St. Louis clay compacts hard through the summer and holds water too long in low spots come spring, which is exactly the structure problem compost is built to fix. Whether you are working beds near the Gateway Arch grounds or a typical south city lot, tilling compost into that clay opens it up so roots and water can move. Zone 6b gives you a workable window in both spring and fall before or after the clay gets too wet or too frozen to till. It is not a one-time fix, clay needs organic matter added regularly to keep behaving.

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.

Frequently Asked Questions

Click a question to see the answer

Answer

Will compost actually help with our clay soil here in St. Louis?

Yes, that's its main job on clay. Compost adds organic matter that opens up compacted clay, improving drainage and letting roots spread. It won't turn clay into loam overnight, but tilling it in at 2 to 3 inches every season or two noticeably improves how the soil drains and crumbles over time.

Answer

How many cubic yards do I need for a 500 square foot bed?

At a 2 inch till-in depth, one cubic yard covers roughly 160 square feet, so a 500 square foot bed needs about 3 cubic yards. For a 1 inch lawn topdress on that same area, you'd only need about 1.5 cubic yards, so confirm your depth before ordering.

Answer

Should I put compost down in spring or fall here?

Both work, compost sells through spring and fall in St. Louis because clay soil benefits from organic matter either time. Spring gets it ready for the growing season, fall lets it break down over winter before last frost around April 10. Pick based on your project, new beds or lawns often do better started in fall.

Answer

Where will the compost be dropped and do I need anything ready?

We place the load wherever you point us at delivery, usually a driveway or curb area close to where you're working. Just make sure that spot is clear and accessible, and let us know if you need it kept off pavement or grass since a full load can leave marks if it sits too long.

Answer

Is compost the same as mulch or topsoil?

No, they do different jobs. Compost is broken-down organic matter meant to feed and structure soil, mulch sits on top to retain moisture and block weeds, and topsoil is bulk fill for building up grade. On St. Louis clay, compost tilled in first followed by mulch on top is a common combination.
