Plan on 3 inches of mulch for established Thornton beds and about 2 inches for tight groundcover plantings where you do not want to bury the crowns. That works out to one cubic yard per 100 to 110 square feet.

UPDATE!
I can’t say enough good things about Mulch Mound! If you read my review below you will see I had a problem with my order. Mulch Mound was quick to respond and solved the issue with my delivery. Will definitely be a customer next year.
First time purchase from Mulch Mound!! First what I liked! Easy to order online and straight forward pricing and delivery. The driver was on time and courteous and delivered my Mulch exactly where I requested! The product is of good quality and comparable to others I have purchased from before. Now what I DID’NT LIKE! I have been mulching the same house and yard for almost 20 years. I always order the same amount and don’t have any issues with covering the same area but this year I fell about a yard short. I was home when the mulch was delivered and when the driver dumped it I noticed that it seemed a bit less than I was used to. I didn’t apply it any thicker than usual and probably a bit thinner than usual because I was worried about running out.
Our delivery was delayed but the new brown color mulch is a nice upgrade to our landscaping.
For Thornton's type of soil, we recommend 2-3 inches for best weed suppression and moisture retention
Try Our CalculatorMeasure each bed separately in feet, length times width, then add the square footage together before you enter it. Curved island beds are easiest to estimate by treating them as a rectangle around the outer edge and subtracting about 20 percent. One cubic yard covers roughly 108 square feet at 3 inches deep.
Most yards in the Thornton area sit on type of soil. Thornton's alkaline clay runs high on the pH scale and packs into dense layers that resist both water and root penetration, which is why azaleas, blueberries, and pin oaks struggle here while iron chlorosis yellows maples and river birch. Plant beds need organic matter added on top and worked in to loosen that structure over time.
Hardwood Mulch
Shredded hardwood is the best fit for Thornton because it slowly releases mildly acidic organic acids as it decomposes, nudging surface pH down and freeing up iron for chlorotic shrubs. Its decomposition also feeds soil biology that opens channels through the clay, so water soaks in instead of running off.
Most Thornton customers pair mulch with a few yards of compost worked into the clay first, plus steel or poly edging to keep mulch out of the bluegrass. Landscape fabric staples and a lightweight mulch fork make spreading day go a lot faster.
Water your beds deeply the day before mulch arrives. Thornton clay is nearly impossible to rewet once it dries into a hard crust, and mulch laid over bone dry soil will keep it that way for weeks. A slow soak that reaches 6 to 8 inches down gives you a moist reservoir under the mulch, and that reservoir is what carries shrubs through the hot, dry stretch between the June rains and the August monsoon bursts.
Watch your drip lines when you mulch. Most Thornton yards run drip emitters under the mulch layer, and a hurried wheelbarrow crew can crush or bury a line so you never notice a leak until the water bill shows up. Flag your emitters with landscape pins before spreading, then run the zone for five minutes afterward and walk the bed looking for dry spots or geysers.
Keep mulch off your foundation and out of window wells. Thornton building lots are graded to move water away from the house, and piling mulch against siding creates a moisture bridge and a highway for earwigs and voles. Leave a 6 inch bare gap along the foundation wall, and if that strip looks unfinished, run a narrow band of 1 inch cobble there instead of organic material.
Thornton sits at 5,351 feet on the northern edge of the Denver metro, where roughly 16 inches of annual moisture has to stretch across a long, sunny growing season. Bare alkaline clay beds here crust over, shed water when the July thunderstorms finally arrive, and bake plant roots during 95 degree afternoons. A 3 inch layer of mulch buffers that soil surface, cuts evaporation dramatically, and keeps root zones 10 to 15 degrees cooler on the hottest days. It also protects perennials during Thornton's freeze thaw whiplash, when a 65 degree February afternoon is followed by a 12 degree night and unmulched crowns get heaved right out of the clay. For most Thornton yards, mulch is the single cheapest way to make a limited water budget go further between the last frost around May 5 and first frost near October 5.
