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.

Compost is sold by the cubic yard and one yard covers about 324 square feet at a 1 inch depth, which is the standard rate for topdressing a lawn. If you are tilling beds at 2 to 3 inches, plan on roughly a third to a half of that coverage per yard, so measure your bed square footage first and work backward from there. Most San Francisco lots run small enough that a single yard handles a lawn topdress or a couple of decent sized beds.

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 of beds, since the compost feeds the soil while the mulch on top holds moisture and keeps weeds down. If you are renovating a lawn, a layer of topsoil under the compost can help level low spots before you topdress and overseed. Neither is required, but most full bed or lawn projects end up using both.

Mulch Mound Pro Tip

On clay loam like most of San Francisco has, do not till compost in deep all at once. Work it into the top 2 to 3 inches of bed soil and let root activity and worms carry it down further over the following months. Tilling it in too deep or too fast in heavy clay can create a layered soil profile where water perches above the compost line instead of draining through, which defeats the purpose of adding it.

Mulch Mound Pro Tip

The most common mistake with compost is treating more as better. A thick layer on a lawn can mat down and suffocate grass instead of feeding it, and over-tilling beds can actually tie up nitrogen temporarily while microbes break down the extra organic matter. Stick to 1 inch for topdressing and 2 to 3 inches worked into beds, and resist the urge to pile it on thicker even if the bed looks like it needs help.

Mulch Mound Pro Tip

Because San Francisco stays mild enough to plant and amend soil nearly year round, you are not locked into one seasonal window like colder cities are. Spring compost applications get beds ready ahead of summer growth, while a fall application lets organic matter break down over the wetter winter months before spring planting. Either timing works here, so schedule around your own project rather than a narrow calendar deadline.

Building Better Soil in San Francisco

Clay loam is common across San Francisco lots, and it holds water and compacts hard between rains, which makes root growth slow and drainage uneven. Compost breaks that structure up over time, adding organic matter that helps clay loam drain better in the wet months and hold moisture better in the dry ones. In a zone 10b climate with a mild year round growing window, you can work compost into beds or top dress lawns in either spring or fall without waiting on a hard frost. It is one of the more direct ways to fix tired soil on a fog belt lot without regrading anything.

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 going to help with San Francisco's clay soil specifically?

Yes, clay loam is exactly the kind of soil compost is meant to improve. The organic matter breaks up compacted clay particles over time, improving drainage and letting roots move through soil that would otherwise stay dense and slow to dry. It will not change the soil overnight, but repeated seasonal applications make a real difference within a year or two.

Answer

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

At the standard 1 inch topdress depth, one cubic yard covers about 324 square feet, so a 500 square foot lawn needs a little over 1.5 cubic yards. Most people round up to 2 yards to have a small buffer for uneven spots, since a light shortfall is easy to fix but running out mid-job is not.

Answer

What is the best time of year to apply compost in San Francisco?

Spring and fall both work well given the mild zone 10b climate here, and there is no hard frost forcing a narrow window like in colder regions. Spring applications set beds up ahead of the growing season, while fall applications let compost work into the soil over the wetter winter months. Pick whichever fits your project timeline.

Answer

Where will the compost be placed if my driveway is narrow?

We drop the load wherever you specify that a delivery truck can safely reach, usually a driveway or curbside spot. If your street or driveway access is tight, let us know the details when you schedule so we can plan the drop location accordingly, since some San Francisco blocks have limited truck clearance.

Answer

Should I get compost or topsoil for my raised beds?

Compost is for feeding and building soil structure, not for filling volume, so it works best mixed into existing soil or layered with topsoil rather than used alone to fill a bed. If you are building a new raised bed from scratch, order topsoil for the bulk fill and compost to mix in at 2 to 3 inches for fertility.
