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.

I needed 3 yards of top soil and that's what I got! Right on time and right where I asked it to be placed (Order# 2041).

One cubic yard of compost covers about 324 square feet at a 1 inch depth, which is the right thickness for a lawn top dressing. For beds, where you want 2 to 3 inches tilled in, figure closer to 110 to 160 square feet per yard depending on how deep you go. Measure your bed or lawn area first, then decide if you are top dressing or amending, since that changes your yardage by a lot.

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 topsoil blend if you are building up a raised bed or leveling low spots before amending. A lot of our Phoenix customers order compost alongside decorative mulch, using the compost to build the soil underneath and the mulch on top to hold moisture in against the sun. If you are seeding or overseeding a lawn this fall, compost topdressing before seed down gives it something better to root into.

Mulch Mound Pro Tip

In Phoenix, spread finished compost thin. An inch on lawns, 2 to 3 inches worked into planting beds, and stop there. Because our native caliche soil drains so fast and holds so little organic matter to begin with, it is tempting to pile it on thinking more will fix things faster. It will not. Excess compost can actually lock up nitrogen and slow your plants down instead of helping, so resist the urge and reapply next season instead.

Mulch Mound Pro Tip

Timing matters more here than in milder climates. Get compost into beds in early fall before the first frost around December 15, or again in late winter before the last frost in early February, so it has time to integrate before summer heat stresses everything. Working compost into bone dry caliche in the middle of July is a losing battle, the soil barely absorbs it and you end up wasting material.

Mulch Mound Pro Tip

If you are amending a large bed, order compost and topsoil together rather than trying to fix depleted caliche with compost alone. A blend of the two gives you the volume to actually build a root zone, while the compost alone is better saved for topdressing lawns or working into soil that already has some structure. This stretches your budget further than compost by itself in a full bed rebuild.

Building Better Soil in Phoenix

Phoenix soil under that caliche layer has almost no organic matter to speak of, which is why beds dry out fast and lawns struggle to hold nutrients through the heat. Compost worked into the top few inches builds the structure that sandy soil is missing, giving roots something to hold onto and improving water retention before the real heat hits. Around Camelback Mountain and through the older Valley neighborhoods with established landscaping, we see a lot of compost going into perennial beds and citrus rings each spring and fall. It is not a one time fix, this soil wants organic matter added regularly.

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

Will compost actually help my soil in Phoenix or is it a waste with all this caliche?

Compost genuinely helps, it is often the single most useful thing you can add to Phoenix soil. Caliche and sandy ground have almost no organic matter on their own, so working compost into the top few inches gives roots structure to grow into and helps the soil actually hold water instead of letting it run straight through.

Answer

How many cubic yards of compost do I need for a 500 square foot bed?

At a 2 inch till depth, one cubic yard covers roughly 160 square feet, so a 500 square foot bed needs about 3 cubic yards. At 3 inches you would need closer to 4.5 yards. Measure your actual bed footprint first since Phoenix lots often have irregular planting areas around block walls.

Answer

When is the best time to add compost to my lawn or beds here?

Spring and fall both work well in Phoenix, and compost sells through both seasons for that reason. Fall application before the December 15 frost gives cool season overseeding a boost, while late winter into early spring ahead of the February 5 last frost sets beds up before summer heat arrives.

Answer

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

We place the load wherever your driveway or a clear area allows truck access, typically a spot about the size of a parking space. You do not need to be home, but someone should confirm access ahead of time, especially if you have a gated community or narrow alley access common in some Phoenix neighborhoods.

Answer

Should I get compost or a topsoil and compost blend for my project?

If you are top dressing an existing lawn or amending beds that already have decent soil, straight compost is what you want. If you are filling a raised bed or rebuilding a planting area where the caliche was scraped bare, a topsoil and compost blend gives you the volume and structure that compost alone cannot provide.
