About this landscape rock

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

Online ordering was really simple and I liked the transparent pricing.

Rock is typically installed 2 to 3 inches deep, and one cubic yard covers about 162 square feet at that 2 inch depth. Measure your bed length by width, decide on depth, and that gives you the yardage to order. Most front bed projects in Columbia run somewhere between 2 and 5 cubic yards depending on how much of the yard is in beds.

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.

Landscape fabric underneath is what makes rock a decade-long install instead of a weed patch, so plan on that as part of the job. Edging, whether steel or stone, keeps rock from migrating into the lawn or driveway, which matters more with clay soil that shifts. A lot of customers pair rock beds near the house with mulch in planting beds further out where they actually want organic matter feeding the soil.

Mulch Mound Pro Tip

In Columbia's clay soil, skip skipping the fabric. Without a barrier, rock will slowly sink into the clay over a couple of seasons and you will end up chasing stones with a rake every spring. Landscape fabric or a compacted base keeps the rock riding on top instead of working its way into the ground, which is the difference between a ten year install and a two year headache.

Mulch Mound Pro Tip

The biggest maintenance mistake with rock beds here is letting leaf litter build up in fall. Columbia has a real autumn drop, and rock traps leaves instead of breaking them down like mulch does. Plan on blowing or raking beds clear a couple times through October and November, otherwise you get a soggy mat sitting on top of the stone that holds moisture against your foundation all winter.

Mulch Mound Pro Tip

Order slightly more than your bare minimum calculation, since rock delivered a little short means a second trip, while a little extra just becomes a small reserve pile for touch ups later. Rock also pairs well with mulch zoned separately, rock tight to the house, mulch further out around plants that actually benefit from organic breakdown, so you are not fighting the material's limits in the wrong spot.

Decorative Stone in Columbia

Columbia sits on heavy clay that holds water after a hard rain, which makes rock a smart choice around downspouts and low spots where mulch would just wash out or mat down. With zone 7b winters and a frost window running late October to late April, rock does not heave or break down the way organic mulch does. A lot of homes here have beds close to the foundation, and rock over fabric keeps that soil away from the house without needing a refresh every season. It is also a practical match for the working-farm, low-fuss landscaping style you see a lot of around town.

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 against my foundation in Columbia's clay soil?

Yes, rock is one of the better choices right against a foundation here. Clay soil holds moisture, and rock does not trap water against the house the way mulch can. Just make sure grading slopes away from the foundation first, since rock will not fix a drainage problem on its own, it just will not make one worse.

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 just under 2 cubic yards. Round up to account for edges and depth variation, most people order 2 to 2.5 yards for a bed that size.

Answer

What is the best time of year to install rock in Columbia?

Anytime outside of frozen or saturated ground works, so avoid the deep clay-mud stretches after heavy winter rain. Late spring through fall, after the last frost around April 22 and before the ground gets soggy in winter, gives you the easiest digging and fabric placement.

Answer

Where will the truck place the rock on delivery day?

The load gets placed at the driveway or staging area you specify when you schedule delivery. Make sure there is clear access for a full size delivery truck, and have a tarp or plywood down if you need to protect a paved surface underneath the pile.

Answer

Should I choose rock or mulch for my front beds?

Rock makes sense if you want a one time install with no annual refresh, especially near the foundation or downspouts. Mulch makes more sense for planting beds where you want organic matter breaking down into the clay soil over time. Many Columbia yards use both, rock near the house, mulch around the plants.
