About this landscape rock

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

I contacted Mulch Mound for #57 river rocks and it was easy and fast to get a delivery right before the holiday weekend. Stone was delivered as promised and place exactly where I asked. Excellent service! I will be ordering mulch next!

One cubic yard covers about 162 square feet at a 2 inch depth, which is the standard install depth for most front yard rock beds. For a typical 400 to 500 square foot bed, that puts most Kennewick jobs in the 2.5 to 3 cubic yard range, and going to 3 inches deep in high traffic spots will use noticeably more. Measure your bed's length and width first, then decide on depth based on whether it's decorative or a walkway.

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 this a decade long install instead of a seasonal chore, since without it the rock slowly works its way into the silt loam beneath. Steel or paver edging keeps everything contained and looks clean against Kennewick's typical xeriscape borders. Many customers pair a rock front yard with a smaller mulch bed near foundation plantings that still need organic matter.

Mulch Mound Pro Tip

In Kennewick's silt loam, skip skimping on landscape fabric thickness. The soil here is fine grained enough that standard woven fabric eventually lets rock and dirt intermix at the edges within a few years if it's thin or overlapped poorly. Spend the extra effort on a heavier commercial grade fabric with generous overlaps, especially near downspouts where water pressure during spring runoff will find any weak seam and push soil up through it.

Mulch Mound Pro Tip

The biggest mistake locally is treating rock beds like mulch beds and forgetting they trap every leaf that blows off a nearby tree instead of breaking it down. Come October, as leaves start dropping ahead of the first frost, plan on blowing or raking rock beds clear a few times through fall. Left alone, decomposing leaf litter builds a thin soil layer on top of the rock that weeds will find within a season or two.

Mulch Mound Pro Tip

Because this is a one time install rather than an annual refresh like bark mulch, it pays to slightly oversize your order rather than run short. A leftover quarter yard is easy to store dry in a bin or tarp for future touch ups after wind or shoveling snow off walkways during Kennewick's colder months. Running short mid job means a second delivery and a visible color seam if the batch varies at all.

Decorative Stone in Kennewick

Kennewick's silt loam drains fast and dries hard, so rock beds here don't fight the mud problems you'd see in heavier clay soils further west. The tradeoff is that in a zone 7b summer, bare rock over dark landscape fabric can bake and radiate heat back at nearby plants, so placement against south facing foundations works better than tucking it around anything that wants shade at the roots. Around downspouts it also does real work, since Kennewick's occasional heavy spring runoff needs something that won't wash out or compost down like bark does. It's a common choice here for the low water, low fuss yards that fit the high desert climate along the Columbia.

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 well in Kennewick's dry summer heat?

Yes, it holds up better than organic mulch in Kennewick's hot dry summers since it won't dry out, blow away, or need replacing after UV breakdown. The main consideration is that rock does radiate heat back toward nearby plants, so it works best as a foundation or walkway groundcover rather than tucked right against heat sensitive shrubs.

Answer

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

At the standard 2 inch depth, one cubic yard covers about 162 square feet, so a 300 square foot bed needs just under 2 cubic yards. Most people round up to 2 cubic yards to have a small buffer for uneven ground or slightly deeper spots near edges.

Answer

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

Not really, since rock doesn't depend on growing season the way mulch or plants do. Many people install before the last frost in early April so beds are settled and clean looking heading into spring, but a fall install ahead of the October frost works just as well and avoids summer heat while you're shoveling.

Answer

Can the delivery truck reach my backyard or side yard?

Delivery trucks place material at a driveway, curb, or accessible drop point on your property, and you'll specify that location at checkout. For backyard or side yard placement, make sure gates are wide enough and clear of obstructions, since the material typically can't be driven directly onto lawns or through tight gaps.

Answer

Should I choose rock or mulch for a Kennewick front yard?

Rock makes sense for low water areas, foundation lines, and spots where you want a permanent look without annual refresh, which fits Kennewick's dry climate well. Mulch is still the better call anywhere you have plants that benefit from organic matter breaking down into the silt loam, so many yards here end up using both in different beds.
