One cubic yard of landscape rock covers about 162 square feet at a 2 inch depth, or a bit less if you go closer to 3 inches for better weed suppression. Measure your bed length by width, decide your depth based on how much foot traffic or drainage you need, and order in full cubic yards since this is a one time install you want to get right the first time.

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 worth doing right the first time, since pulling rock back up later to fix a bad base is nobody's idea of a good Saturday. Steel or aluminum edging keeps the stone from migrating into the lawn during spring runoff, and a few larger accent boulders can break up a flat rock bed nicely if you are going for a more natural mountain look.

Mulch Mound Pro Tip

Lay landscape fabric before the rock, not after, and overlap seams by at least six inches since Columbia Falls gets enough freeze thaw movement to shift ground and open gaps over a season or two. Skipping fabric means rock slowly works itself into the sandy loam below, and within a few years you are pulling stone out of dirt instead of enjoying a clean bed.

Mulch Mound Pro Tip

The biggest mistake we see locally is piling rock right up against tree trunks or foundation walls with no gap, which traps moisture during spring melt and invites rot or pest issues. Leave a few inches of clearance around any wood surface or trunk, and slope the bed slightly away from the house so water keeps moving instead of sitting.

Mulch Mound Pro Tip

If you are covering a large area, consider mixing in a coarser base layer under a finer decorative top layer rather than one deep pour of the same rock, since it uses less material overall and drains better through our sandy soil. This also pairs well with boulders or steel edging if you want a layered, intentional look instead of a flat rock field.

Decorative Stone in Columbia Falls

Sandy loam drains fast around here, which is good news for rock because it means water moves through instead of pooling under the stone and rotting whatever fabric or soil is beneath it. With the first frost landing mid September and the last one not clearing until mid April, this is a zone 5b landscape where a lot of plant based mulch needs replacing every year or two, but rock does not. People near the Hungry Horse Dam area and up toward the valley floor use it heavily along foundations and in xeriscape style beds where they are done fighting the short growing season for a manicured lawn look. It also handles wind well, which matters given how the valley funnels gusts down from Glacier.

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 sink into the ground here over time?

Not if fabric is installed underneath first. Our sandy loam drains well but it is loose enough that rock without a barrier will slowly settle into the soil over a few years. With fabric down, the rock stays on top and the install is genuinely a one time job.

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 a little under 2 cubic yards. Round up to 2 full yards to account for uneven ground and a bit of settling.

Answer

Is there a bad time of year to install rock in Columbia Falls?

Late fall right before the first frost around September 16 is tougher since the ground can be wet or already firming up. Spring after the last frost in mid April through early fall gives you workable, dry sandy loam that is much easier to grade and set fabric into.

Answer

Will the delivery truck be able to reach my driveway?

Most residential driveways in the area handle our trucks fine, but let us know about narrow access, steep grades, or low hanging trees when you schedule. We place the load as close to your work area as the truck can safely get.

Answer

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

Rock is the better call right against foundations since it does not hold moisture against the wall the way organic mulch can, and it will not need replacing every year or two. Mulch still wins if you have plants nearby that benefit from organic matter breaking down into the soil.
