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. For garden beds, plan on tilling in 2 to 3 inches, which cuts coverage down to roughly 108 to 160 square feet per yard. Measure your bed or lawn area first, then match it to the depth you actually need rather than rounding up.

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.

Complete Your Outdoor Project

Compost pairs well with a bark or wood mulch layer on top once it's worked into a bed, since the compost feeds the soil while the mulch holds moisture and temperature steady. For lawn projects, some people follow a topdressing with a light layer of screened loam if they're overseeding bare patches. If you're building new beds from scratch, ordering compost and a topsoil blend together in the same delivery saves a second trip.

Mulch Mound Pro Tip

Cambridge's silt loam already holds water, so compost worked in too wet turns into a sealed, airless layer instead of loosening anything. Wait until the bed has dried out enough to crumble in your hand before tilling in that 2 to 3 inches. If you're topdressing a lawn in spring, do it after the ground has fully thawed and drained, usually a couple weeks past that April 25 last frost date, not the first warm day.

Mulch Mound Pro Tip

The most common mistake is piling compost on thick thinking it'll feed the lawn faster. At more than an inch on turf, compost can mat down grass blades and actually lock up nitrogen as it finishes breaking down, which is the opposite of what people want. Thin and even is the rule, rake it out so you can still see grass tips through it, and let it work down on its own over a few weeks.

Mulch Mound Pro Tip

If you're amending several beds across a property, it's more efficient to order one larger cubic yard delivery than to buy bagged compost in batches, both in cost per yard and in the number of trips you make with a wheelbarrow. Pair it with a fall leaf cleanup timeline, since working compost into beds right after clearing leaves but before the October 15 frost gives it a head start before winter.

Building Better Soil in Cambridge

Silt loam around Cambridge drains fine on paper but tends to crust and compact, especially in the older lots near Harvard where soil has been worked hard for a century. Compost breaks that crust up and gives roots somewhere to go before the ground freezes in mid October. With a growing season bookended by an April 25 last frost and that October 15 first frost, there are two real windows each year to work compost in, spring for beds going in and fall for lawns recovering from summer stress. It also helps buffer the freeze thaw cycles that heave beds over a Zone 6b winter.

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

Is this compost finished enough to use right away in my garden beds?

Yes, this is finished compost that has been turned and stabilized, not raw yard waste. It's ready to till directly into beds at 2 to 3 inches or spread as a thin lawn topdressing at 1 inch. You don't need to let it cure further, though working it in a week or two before planting gives soil biology time to settle.

Answer

How many cubic yards 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 amending a garden bed instead at 2 to 3 inches deep, plan on closer to 6 to 9 cubic yards for the same footprint.

Answer

Should I put compost down in spring or fall here?

Both work, and that's why we deliver it both seasons. Spring compost suits new beds and gives plants a boost heading into the growing season, while fall compost timed before the October 15 frost helps lawns recover from summer stress and lets organic matter break down over winter. Pick based on your project, not the calendar.

Answer

Where will the delivery truck place the pile, and what do I need to prepare?

The driver places the load wherever you direct on delivery day, typically a driveway, curb strip, or other flat accessible spot. Clear the area beforehand and make sure there's enough clearance for the truck to back in. If your access is tight, mention it when you schedule so we can plan accordingly.

Answer

What's the difference between this compost and topsoil or loam?

Compost is decomposed organic matter meant to feed soil and improve structure, it's not a standalone growing medium. Topsoil and loam are mineral based and used as a foundation or fill. Most Cambridge projects use compost mixed into existing silt loam rather than as a replacement for it, since the silt loam already provides structure that just needs organic matter worked in.
