One cubic yard of compost covers about 324 square feet at a 1 inch depth, which is right for lawn topdressing. For garden beds getting a 2 to 3 inch tilled-in application, plan on closer to 110 to 160 square feet per yard depending on depth, since compost is meant to go on thin and get worked in rather than piled 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.

Compost pairs well with a coarser mulch on top of beds, since the compost feeds the soil while mulch on top holds moisture and blocks weeds. If you're dealing with Portland's rockier pockets, some loam or topsoil delivered alongside the compost can help level out low spots before you till it in.

Mulch Mound Pro Tip

Finished compost should smell like earth, not sour or ammonia-like. If it's raw or still hot, let it sit a few weeks before working it in, especially in Portland's cooler soil temperatures where breakdown slows. Tilling in 2 to 3 inches for new beds gives the rocky loam here real structure, but topdressing lawns should stay at 1 inch max so grass blades aren't smothered going into a Maine winter.

Mulch Mound Pro Tip

A common mistake is treating compost like mulch and piling it on thick expecting faster results. More is not better, excess compost can actually lock up nitrogen and other nutrients as it continues to break down. Stick to 1 inch on lawns and 2 to 3 inches tilled into beds, then let the material do its work over a season rather than trying to solve years of poor soil in one application.

Mulch Mound Pro Tip

Fall applications ahead of Portland's October 5 frost date give compost a head start breaking down over winter, so beds are ready to plant come the May 5 last frost. Spring works too if you're building new beds before planting season. Pairing a compost order with mulch or loam in the same delivery saves a second trip and gets your whole bed prepped in one weekend instead of two.

Building Better Soil in Portland

Rocky loam around Portland drains fast in spots and holds tight clay pockets in others, and compost helps even that out by adding organic matter that improves both extremes. With a growing season bounded by a May 5 last frost and an October 5 first frost, there is a workable spring window and a fall window before the ground shuts down, and compost fits either one. Gardeners here often use it to rebuild beds hit hard by winter freeze thaw cycles, and lawns benefit from a thin fall topdressing before dormancy. Zone 5b winters are tough on soil biology, so feeding it back each season keeps beds productive.

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

Is this compost finished enough to use right away, or does it need to sit?

Our compost is fully turned and finished, so it is ready to work into beds or topdress lawns without waiting. It should smell earthy rather than sour. You can till it into rocky loam beds or spread it on lawns the same day it arrives, no curing period needed.

Answer

How much compost do I need for a 500 square foot garden bed?

At a 2 inch tilled-in depth, one cubic yard covers roughly 160 square feet, so a 500 square foot bed needs about 3 cubic yards. If you're going with a lighter 1 inch application, closer to 1.5 cubic yards would work, though beds usually benefit from the deeper mix.

Answer

Should I put compost down in spring or fall in Portland?

Both work well here. Fall applications ahead of the October 5 frost let compost break down over winter and feed soil biology before spring planting. Spring works if you're building new beds or want an immediate boost heading into the growing season. The material itself doesn't care which season, it's about your project timeline.

Answer

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

We place the load wherever you specify at checkout, typically a driveway or other flat, accessible area. You don't need to be home, but the spot should be clear and reachable by a delivery truck. Delivery timing is scheduled at checkout rather than a fixed same-day window.

Answer

Should I get compost or topsoil for my rocky loam beds?

Compost adds organic matter and feeds soil biology, which is what Portland's rocky loam typically needs most. Topsoil is better if you're actually building up grade or filling low spots. Many people here use both, topsoil to level and compost tilled in on top to improve structure and fertility.
