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.

Wonderful experience! They put the mulch exactly where we wanted. This mulch spread very easily and didn’t have the usual “mulch smell.” We will definitely use again!

One cubic yard of this compost covers about 324 square feet at a 1 inch depth, which is the right amount for lawn top dressing. If you're tilling into a bed at 2 to 3 inches, plan on roughly 108 to 160 square feet per yard, so measure your bed area 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.

Compost pairs well with a mulch top layer once it's worked in, since the mulch holds moisture over the amended soil and cuts down on how often you're watering. If you're building new beds instead of refreshing old ones, a lot of San Diego customers order topsoil first and compost second to blend in on site.

Mulch Mound Pro Tip

In San Diego's sandy clay, don't till compost in deeper than 3 inches even if the bed looks like it can take more. Excess compost in heavy clay-leaning soil can actually tie up nitrogen temporarily as microbes work through it, which sets plants back rather than helping. Thin and repeated applications over a couple seasons beat one heavy dump, especially in beds that already have established roots you don't want to disturb.

Mulch Mound Pro Tip

The most common mistake with compost here is applying it right before a Santa Ana wind event or a dry stretch, when it dries out on top before it has a chance to work down into the soil. Water it in lightly after spreading, especially on lawn top dressing, so it settles against the soil surface instead of just sitting there and blowing around.

Mulch Mound Pro Tip

Compost and mulch do different jobs, compost feeds and structures the soil while mulch just protects the surface, so buying both together instead of one thick layer of either gets better results per yard. If you're amending a large bed, ordering compost in spring or fall ahead of planting season means it has time to integrate before roots need it.

Building Better Soil in San Diego

Sandy clay is the soil most San Diego yards are working with, and it tends to compact and shed water instead of absorbing it. Compost breaks that up over time, giving roots somewhere to actually spread in Zone 10b's long growing season. Around Balboa Park and older San Diego neighborhoods you see a lot of established beds that need a yearly refresh rather than a full rebuild, and thin applications of finished compost do that without overwhelming the soil. It works for lawn top dressing too, especially on the warm season turf that struggles when this soil dries out and hardens.

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

Answer

Is this compost finished enough to plant into right away?

Yes, this is finished and stable compost, not raw or actively hot material, so it will not burn roots or tie up nutrients the way unfinished compost can. You can till it into beds and plant within a week or two once it's mixed into the soil.

Answer

How much compost do I need for a 500 square foot lawn top dressing?

At a 1 inch depth, one cubic yard covers about 324 square feet, so a 500 square foot lawn needs a little over 1.5 cubic yards. Round up slightly since spreading is never perfectly even.

Answer

When is the best time to apply compost in San Diego?

Spring and fall both work well here given the mild Zone 10b climate, since neither season brings the extreme heat or cold that stresses new amendments. Avoid applying right before a long dry, windy stretch so the compost has a chance to settle into the soil rather than drying out on the surface.

Answer

Where will the compost be placed on delivery day?

We place it at the driveway, curb, or other access point you specify at checkout. Make sure there's clear truck access and enough room for the pile, and let us know ahead of time about gates, slopes, or narrow passages.

Answer

Should I get compost or topsoil for my sandy clay beds?

If your beds already have soil and just need structure and nutrients, compost alone is usually enough. If you're building new beds or dealing with heavily compacted areas, topsoil blended with compost gives you both volume and the amendment benefit in one pass.
