I used Mulch Mound to have 3 cubic yards of garden soil delivered. The process was easy and I love that I didn't have to call anyone. I placed my order online, picked my delivery date, laid out my tarp and the dirt was delivered. My delivery had to be pushed back, but I was kept informed via text, which was great. So why not 5 stars? The description of garden soil on the website is "A balanced mix of topsoil and organic amendments ready for raised beds, flower gardens, and new planting areas. Good drainage, solid nutrients, easy to work with." What I got was more like fill dirt. It had a lot of gravel, a lot of clay, and random trash mixed in. I didn't test the soil to see if it actually had "amendments" because I already have compost and alpaca manure ready to add, but if I'd known the quality of the dirt was going to be the same as the bagged dirt I bought last year, I probably would have gotten 2 yards of top soil and a yard of leaf compost for better quality, especially since the leaf compost is cheaper.

Measure your area in feet and break irregular yards into simple rectangles and triangles rather than trying to estimate the whole shape at once. Subtract the square footage of planting beds, patios, and driveways so you are not paying for coverage you do not need. Stone is heavy, so ordering accurately matters more here than with lighter materials.
Complete Your Outdoor Stone Project
Pair your rock with steel or concrete edging to hold clean lines against sandy loam, and consider boulders or a few larger accent stones to break up the expanse. Mulch in the planting beds themselves keeps plant roots cooler than rock does.
Set your rock depth by exposure and traffic, not by one number across the whole yard. Open sunny areas where weed seed lands need a full 3 inches to keep sunlight off the soil. Under a mesquite or palo verde canopy, 2 inches is plenty and the extra depth would just collect dropped leaves. Walkways get 2 inches of a finer material so they compact firm underfoot rather than shifting with every step.
Mulch Mound Pro Tip
Apply pre emergent twice a year, in late February and again in early September, timed just ahead of our two germination windows. Water it in right after application because Fortuna Foothills rainfall will not do it for you. This single habit does more to keep a rock yard clean than fabric ever will, and it targets the windblown seed that actually causes most of the weed pressure here.
Mulch Mound Pro Tip
Choose your rock color with the afternoon sun in mind. Dark basalt and charcoal tones look sharp in a photo but absorb serious heat and can push surface temperatures well past what is comfortable near a patio. Lighter tans, golds, and buff tones common to this part of the Yuma area reflect more, stay cooler, and hide the inevitable dust film far better between refreshes.
The Unique Landscape of Fortuna Foothills
Decorative rock is the dominant ground cover across Fortuna Foothills for good reason, since it handles 110 degree summers, monsoon downpours, and near total sun exposure without breaking down or needing replacement. With only 3 inches of annual rainfall there is no practical case for large turf areas, and stone gives you a finished, permanent surface that never needs water. It also handles the sudden runoff that comes with monsoon season, when a single August storm can drop an inch in under an hour and move unprotected sandy loam right off your property. Rock reflects heat rather than absorbing organic breakdown, so it stays stable in ways mulch cannot in this climate. From decomposed granite pathways to river rock in drainage swales to larger rip rap on slopes, stone is the backbone of a functional low water landscape here.
Frequently Asked Questions

Answer
What size rock is best for a full front yard here?
Half inch to three quarter inch screened rock is the Fortuna Foothills standard and works well for a reason. It is small enough to walk on and rake, large enough that it does not blow around in spring winds, and it locks together into a stable surface. Anything under a quarter inch tends to compact into a hardpan, and anything over an inch and a half is uncomfortable underfoot and traps windblown debris.
Answer
Does landscape rock make my yard hotter?
Rock does absorb and radiate heat, and a large expanse of it will raise the temperature immediately around your house. You can manage that by keeping rock lighter in color rather than dark, shading the west and south sides with trees or ramadas, and using mulched planting beds near windows and patios instead of wall to wall stone. A mix of rock and planted areas reads much cooler than an unbroken gravel field.
Answer
Do I need fabric underneath the rock?
It is a genuine tradeoff. Fabric slows weeds for the first few years, but in Fortuna Foothills the real weed source is windblown seed landing on top of the rock and germinating in accumulated dust after a monsoon. Fabric does nothing about that and eventually tears and surfaces looking ragged. Many local installers now skip fabric in planted areas and rely on adequate rock depth plus a pre emergent instead.
Answer
How do I keep rock from washing out during monsoon storms?
Monsoon runoff in the foothills moves fast because the ground is hard and dry when the storm hits. Use larger stone, one and a half inch or bigger, in any natural drainage path or swale, and set solid edging or a header at the low end of sloped areas. Small screened rock on a slope with concentrated flow will end up in the street after one good August storm.
Answer
How often does landscape rock need to be refreshed?
The rock itself lasts indefinitely, but expect to top dress every five to eight years. What happens in Fortuna Foothills is that windblown dust and fine sand fill the voids between stones and the surface gradually looks dull and grey. A fresh inch of the same material restores the color, or you can rake and rinse the existing rock if the fill is not too deep.
Answer
Can I put rock right up against my house foundation?
Yes, and it is actually the preferred approach here. A band of rock 18 to 24 inches wide along the stucco keeps organic material away from the slab, discourages termite activity, and gives water a clean path away from the foundation. Just keep the rock surface an inch or two below your weep screed so moisture is not wicking into the wall.
Answer
Will decomposed granite hold up as a driveway or path?
For walkways and casual paths it does very well in this dry climate, compacting into a firm surface that sheds water. For anything carrying vehicle traffic, use a stabilized DG with a binder or you will get ruts and washboarding. The bigger concern in Fortuna Foothills is monsoon runoff cutting channels through it, so crown the path slightly and edge it well.
Answer
Is there a stone yard near Fortuna Foothills?
Covering a yard with rock that can handle monsoon runoff and summer sun usually means choosing between hauling it yourself from a stone yard or having it delivered to the spot. In Fortuna Foothills, Mulch Mound skips the trip, since we are not a quarry, and we drop crushed stone right where you want it.
