About this landscape rock

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

We had a great experience today. This was our first time using Mulch Mound, and I found the price competitive and the online ordering very easy. We are impressed with the quality of the mulch, too! It is covering well - a great value!

At a 2 to 3 inch install depth, one cubic yard of rock covers about 162 square feet at the shallow end of that range. Measure your bed's square footage first, then account for edges and any depth you want deeper near downspouts or drainage paths. Most Columbia front yard beds run between 2 and 4 cubic yards depending on how much of the lot is in rock versus lawn.

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 yard is approximately 27 cubic feet. As a general guideline, one yard of material can cover an area of about 10 feet by 10 feet at a few inches deep.

Landscape fabric underneath is what makes this a decade install instead of a five year one, so plan on that as a companion order. Edging, whether steel or paver, keeps rock from migrating into the lawn during Columbia's heavier summer downpours. If any beds border planting areas that need real soil feeding, keep a mulched bed separate rather than mixing the two.

Mulch Mound Pro Tip

Lay landscape fabric before the rock goes down, always. Columbia's clay soil holds moisture close to the surface, and rock placed directly on bare clay will slowly work itself down into the mud over a season or two, especially near downspouts where water concentrates. Fabric keeps the rock riding on top where it belongs and keeps clay from bleeding up through the stone during heavy summer rain, which is common here from June through August.

Mulch Mound Pro Tip

The most common mistake in Columbia yards is skipping gutter and downspout planning before the rock goes in. Route downspout discharge into a shallow gravel channel or splash block under the rock bed first, otherwise concentrated runoff during a Carolina thunderstorm will carve a channel straight through your fresh install and undermine the fabric edges within a season.

Mulch Mound Pro Tip

Order rock and edging together rather than as separate trips, since edging is what keeps a one time rock install actually staying one time. Steel or paver edging holds the line where rock meets lawn, which matters more in Columbia than drier climates because St. Augustine and centipede lawns common here spread aggressively into loose rock beds without a firm barrier.

Decorative Stone in Columbia

Columbia's clay soil holds water long after a storm rolls through, which is exactly why rock groundcover works so well around downspouts and low spots here. Once it's down over fabric, it sheds rain instead of turning to mud like exposed clay does. With zone 8a summers pushing heat and humidity most of the year, rock beds near the State House and in older Columbia neighborhoods stay put without the mildew and rot that mulch can develop in the wet season. It is a one time install that outlasts the clay's freeze thaw churn through winter.

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

Click a question to see the answer

Answer

Will landscape rock work well with Columbia's clay soil?

Yes, and it actually helps. Clay drains slowly, so rock over fabric on top of it sheds water instead of holding it against your foundation. Skip laying rock directly on bare clay though, use fabric as a barrier or the stone will slowly sink into the mud over a wet season or two.

Answer

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

At a 2 inch depth, one cubic yard covers about 162 square feet, so a 300 square foot bed needs roughly 2 cubic yards. Bump that toward 2.5 yards if you want a fuller 3 inch depth or if the bed has curves and edges that waste material.

Answer

When is the best time to install rock in Columbia?

Late fall through early spring, before the last frost around March 25, is easiest on you and the ground. Clay soil is firmer and easier to prep for fabric in cooler months, and you avoid installing during Columbia's peak summer humidity when the work is miserable and the clay underneath can be sticky and hard to level.

Answer

Where will the delivery truck place the rock?

The truck drops the load at your curb, driveway, or another accessible spot you specify, and delivery is scheduled at checkout once you place your order. Make sure the drop zone has clear overhead access and firm ground, since Columbia's clay turns soft after rain and can rut under a loaded truck.

Answer

Should I choose rock or mulch for a bed near my house foundation?

Rock is the better call right against a foundation, since it does not hold moisture against siding or attract wood pests the way mulch can. It is a one time install rather than an annual refresh, though it will not feed the soil, so save mulch for beds where you actually want plants drawing nutrients from what's underneath.
