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 rock covers about 162 square feet at a 2 inch depth, which is the standard install for groundcover beds and foundation borders. Go to 3 inches in high traffic spots or where you want better weed suppression, which drops coverage to around 108 square feet per yard. Measure your bed square footage first, then divide by the coverage number for your chosen depth.

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.

We have always spread our own mulch for the past 24 years. This was our first time with the Mulch Mound - things I liked: they have online ordering and provide a digital receipt which means you can remember how much you ordered (I always forget for the next year!), they were on time, they were able to deliver in 48 hours, they were generous with the portion (we got 9 yards and it felt like a FULL nine yards!), the driver was polite! We have ordered from reputable places, and there is always a little trash in the mulch. The mulch we recv'd from Mulch Mound had barely any... we were pleasant surprised!!! Color was great! Not to mention - the price was competitive and LOWER than other mulch places around. We will use again !! Highly recommend! Thanks Mulch Mound!

Landscape fabric goes down before the rock, not after, and it is worth the extra step given how heavy clay soil pushes rock down into bare dirt over a season. Steel or aluminum edging keeps the rock line crisp against turf, especially useful along the curving beds common in Thornton subdivisions. A lot of customers pair rock borders with mulch in the planting beds themselves, so the rock frames the yard and the mulch feeds the plants.

Mulch Mound Pro Tip

In Thornton's clay, lay landscape fabric before the rock and overlap seams by at least 6 inches, because clay shifts slightly with our freeze thaw cycle between October and May and gaps in the fabric let rock sink into the soil below. Skipping fabric on clay means you are re-leveling the bed within a couple of seasons instead of getting the decade-long groundcover rock is supposed to deliver.

Mulch Mound Pro Tip

The biggest mistake we see locally is planting into rock beds expecting organic growth, then wondering why shrubs struggle. Rock over fabric blocks the soil feeding that plants need, so it works best as a true groundcover, not a planting medium. If you want plantings in the bed, cut fabric openings and back-fill with actual soil rather than spreading rock right up to the stems.

Mulch Mound Pro Tip

Order the full bed in one delivery instead of buying rock in batches, since matching color and stone size across separate loads gets harder over time as quarry batches shift. If your project includes both a rock border and mulched planting beds, scheduling both deliveries together saves a trip and gets your whole yard finished in the same weekend.

Decorative Stone in Thornton

Thornton's alkaline clay does not drain fast, and rock over landscape fabric keeps water moving away from foundations instead of pooling against them, which matters with the freeze thaw swings between our May and October frost dates. At 5,351 feet the UV load is high and organic mulches bleach and break down faster here, but rock does not care about sun exposure. It also will not blow around in the wind that comes off the plains east of town. The tradeoff is that it traps cottonwood leaves and pine needles, so beds near mature trees need an occasional blow out.

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 with Thornton's clay soil or should I amend first?

Rock sits on top of fabric over your existing clay, so no amending is needed underneath it. The clay actually helps here since it is stable and will not let rock sink as fast as loose sandy soil would. Just make sure the bed is graded so water sheds away from your foundation before you lay fabric.

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. Round up to 2 yards to account for uneven edges and settling. If you are going 3 inches deep for better weed control, plan closer to 3 cubic yards.

Answer

What time of year is best to install rock in Thornton?

Late spring after the last frost around May 5 or early fall before October gives you dry ground to work with and comfortable temperatures for the physical labor of spreading rock. Avoid installing right after heavy spring runoff when clay soil is saturated, since compacting wet clay under fabric leads to uneven settling later.

Answer

How does delivery work if my driveway is narrow or I have a fence gate?

Let us know your access details when you place the order so the truck can position for the drop, whether that is a driveway placement or a spot closer to a side gate. Most Thornton lots handle a standard delivery fine, but tight side yards may need the load placed at the curb for you to wheelbarrow in.

Answer

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

Rock is the better call right against foundations since it will not hold moisture against siding or attract wood-eating insects the way organic mulch can over time. It is also a one time install rather than an annual refresh, which suits high wind, high UV spots at our elevation. Save mulch for beds with plants that actually benefit from the organic breakdown.
