About this landscape rock

Smooth tumbled river rock, heavy enough to stay put in drainage runs and handsome enough for beds and borders.

One cubic yard of landscape rock covers about 162 square feet at a 2 inch depth, or a bit less at the deeper 3 inch depth we recommend for foundation beds and heavy foot traffic areas. Measure your bed's length and width, decide on 2 or 3 inches, and order in full cubic yards since this is a one time install you want done right the first time. Most San Marcos front yard beds run 2 to 4 yards depending on how much lawn is being converted.

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.

A ton is 2,000 pounds of material. As a general guideline, one ton of rock covers roughly 100 square feet at 2 inches deep, depending on rock size and density.

Landscape fabric underneath is what makes this a decade long install instead of a rock pile that grows weeds through it within a year. Steel or paver edging keeps the stone from migrating into St. Augustine lawns, which is a common complaint we hear on the newer subdivisions near the outer loop. A little topsoil to regrade low spots before the fabric goes down helps the rock actually shed water instead of sitting in it.

Mulch Mound Pro Tip

San Marcos clay swells when it's wet and cracks when it dries, which means fabric alone can shift over a season or two as the ground moves underneath it. Compact the soil and grade a slight slope away from the foundation before laying fabric, then pin it every 2 feet instead of every 4. That extra pinning keeps the fabric from tenting up through the clay's seasonal movement, which is the main reason rock beds around here look uneven after a year.

Mulch Mound Pro Tip

The biggest mistake we see is skipping edging because it seems optional. Without a hard edge, rock migrates into St. Augustine and Bermuda lawns within a season, especially along the sloped lots near the river where water pushes it downhill during a hard rain. Steel edging set 2 to 3 inches deep solves this permanently and it is far cheaper than repeatedly raking rock back where it belongs.

Mulch Mound Pro Tip

Rock pairs well with a one time load of quality soil to regrade before installation, since San Marcos clay is often too uneven for even coverage otherwise. Order both in the same delivery window to save a trip, and consider a slightly deeper 3 inch layer near downspouts and low areas where water concentrates after storms rolling off the springs area, since a thin layer washes thin there first.

Decorative Stone in San Marcos

San Marcos sits on alkaline clay that holds water after a storm off the river and then bakes hard in August. Rock sheds that runoff instead of letting it pool against a foundation, which matters with the humidity this town gets near the springs. It also does not break down or wash out the way mulch does after a zone 9a summer, so beds near downspouts and low spots stay put year after year. A lot of the newer builds around San Marcos use it as the entire front bed treatment instead of turf, since it needs no water once it is down.

What Landscape Rock Is

Landscape rock is stone chosen for how it looks as much as what it does. River rock is smooth and rounded, decomposed granite is fine and packs firm underfoot. Both are sold by the cubic yard for beds, borders, paths, and dry creek beds.

River Rock vs Decomposed Granite

River rock stays loose and rolls, so it suits beds, borders, and drainage runs where it can sit in place. Decomposed granite compacts into a firm surface, so it suits paths, patios, and anywhere you will walk or roll a wheelbarrow.

Depth and Coverage

Spread river rock 2 to 3 inches deep over landscape fabric so it stays put and weeds stay down. Lay decomposed granite 3 to 4 inches deep, wet it, and compact it in lifts for a surface that sheds water instead of rutting.

Frequently Asked Questions

Answer

Will landscape rock work with San Marcos clay soil or do I need to amend it first?

Rock does not need amended soil since it sits on top of fabric rather than mixing into the ground. In fact it is one of the better options for our clay because it doesn't need the organic matter mulch does, and it drains surface water away rather than letting it pool the way clay tends to on its own.

Answer

How many cubic yards do I need for a 300 square foot front bed?

At the standard 2 inch depth, one yard covers about 162 square feet, so a 300 square foot bed needs just under 2 cubic yards. We'd suggest rounding up to 2 full yards, and going to 3 yards if you want the deeper 3 inch depth for a foundation bed or high traffic path.

Answer

What time of year is best to install rock in San Marcos?

Late fall through early spring works well here, roughly November through March, since you're working before the first heavy heat and outside the worst of the humid stretch. It also lands after our first frost around November 8 and before last frost in mid March, so the ground is workable without the August clay turning rock hard on you mid install.

Answer

Where will the rock be dropped and can your truck get down my driveway?

We place the load in your driveway or another accessible spot you specify at checkout, dropped as a single pile rather than spread. Make sure there's clear overhead clearance and a firm surface for a loaded truck, and let us know at checkout if your street or driveway has tight turns or a steep grade so we can plan the drop.

Answer

Should I choose landscape rock or mulch for my San Marcos yard?

Rock is the better call for foundation beds, downspout areas, and anywhere you want a one time install that doesn't need refreshing, especially given how our clay holds water. Mulch is worth it if you're planting beds that benefit from organic matter breaking down into the soil. Many San Marcos yards use both, rock near the house and mulch around planted beds further out.
