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.

Delivery was smooth and on time!
The triple shredded mulch was great quality and just what we were looking for.

One cubic yard covers about 324 square feet at a 1 inch depth, which is the right amount for topdressing an established lawn. For bed work, where you are tilling in 2 to 3 inches, plan on roughly one cubic yard covering 100 to 160 square feet depending on depth. Measure your square footage first, then decide if you are dressing or amending, since the two uses call for very different volumes.

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 mulch topcoat once it is worked into beds, since the mulch holds moisture in and keeps the compost from drying out on top. If you are starting new beds in DC's silt loam, some gardeners bring in a bit of coarse sand or topsoil alongside the compost to improve drainage before planting.

Mulch Mound Pro Tip

In DC's silt loam, spread finished compost no thicker than 2 to 3 inches when working it into beds, then till it into the top 6 inches rather than leaving it as a surface layer. Thicker layers left untilled can crust over in our humid summers and actually shed water instead of absorbing it. For lawns, keep it to a thin 1 inch topdress and rake it in so it does not smother grass blades.

Mulch Mound Pro Tip

A common mistake is applying compost right before a heavy rain event, which are frequent here in spring and late summer. Fresh compost can wash off sloped yards before it has a chance to work in. Water lightly after applying instead of relying on rain, and check the forecast so you are not laying it down ahead of a downpour that undoes the work.

Mulch Mound Pro Tip

Fall and spring are both solid windows for compost here, so there is no need to rush a single season. Ordering once in bulk for both your lawn topdress and bed amendment in the same delivery saves a second delivery fee and keeps material fresh rather than sitting bagged in a garage over winter.

Building Better Soil in Washington

Washington's native silt loam is decent soil but it compacts easily under foot traffic and holds water unevenly, especially in the older neighborhoods near the National Mall where fill soil is common. Compost worked into the top few inches loosens that structure and gives roots somewhere to spread. With zone 7b winters that are mild and summers that run hot and sticky, compost also buffers soil temperature swings and helps beds hold onto moisture between rains. It is the material most DC gardeners reach for before they touch fertilizer.

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 compost the same as topsoil for my DC rowhouse yard?

No, compost is a soil amendment, not a growing medium on its own. It is decomposed organic matter meant to be mixed into existing soil or used as a thin topdress, while topsoil is the base layer plants root into. In DC's silt loam, most yards need compost worked into existing soil rather than a full topsoil replacement.

Answer

How many cubic yards do I need for a 1000 square foot lawn?

At a 1 inch topdress depth, one cubic yard covers about 324 square feet, so a 1000 square foot lawn needs roughly 3 cubic yards. If you are amending a bed instead at 2 to 3 inches, expect to need closer to 6 to 9 cubic yards for the same square footage.

Answer

When should I put down compost in Washington DC, spring or fall?

Both work, compost sells here in spring and fall and either season suits our zone 7b climate. Spring application gets beds ready before summer heat, while fall application lets compost break down over our mild winter and be ready for spring planting. Pick based on your project timeline rather than the calendar.

Answer

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

We place the load on a hard, accessible surface like a driveway, and you do not need to be home as long as we have clear access and a spot identified. Just make sure the drop area is clear and any gates or narrow alley access typical of DC rowhomes are accounted for ahead of time.

Answer

Should I get compost or mulch for my new garden beds?

Compost improves the soil itself, feeding structure and nutrients, while mulch sits on top to retain moisture and block weeds. Most DC beds benefit from both, compost tilled in first, then a mulch topcoat. If you are only doing one this season, prioritize compost since it is doing the structural work.
