I used Mulch Mound to have 3 cubic yards of garden soil delivered. The process was easy and I love that I didn't have to call anyone. I placed my order online, picked my delivery date, laid out my tarp and the dirt was delivered. My delivery had to be pushed back, but I was kept informed via text, which was great. So why not 5 stars? The description of garden soil on the website is "A balanced mix of topsoil and organic amendments ready for raised beds, flower gardens, and new planting areas. Good drainage, solid nutrients, easy to work with." What I got was more like fill dirt. It had a lot of gravel, a lot of clay, and random trash mixed in. I didn't test the soil to see if it actually had "amendments" because I already have compost and alpaca manure ready to add, but if I'd known the quality of the dirt was going to be the same as the bagged dirt I bought last year, I probably would have gotten 2 yards of top soil and a yard of leaf compost for better quality, especially since the leaf compost is cheaper. Photo of my mountain of dirt and just some of the trash I found in it.

I had a great experience ordering from Mulch Mound- they offered a quick turnaround and they delivered a generous/heaping 4 cubic yards. Driver was kind and professional, couldn’t have asked for an easier or better experience.

My experience with Mulch Mound was great and super easy. I ordered two yards of screened topsoil and was able to get it delivered within 2 days. They came in my requested time frame (afternoon) and dropped it off where I asked on my driveway. The topsoil was exactly what was advertised, clean with no rocks or other debris. The price was reasonable. I plan to use them again in a couple weeks to order compost for my garden beds.

Mulch Mound Pro Tip

Gunbarrel's open eastern exposure funnels downslope winds across yards with little to block them, so lightweight shredded mulch tends to migrate into driveways. Choose a coarser bark nugget or double shredded cedar that knits together, keep depth at three inches, and water the surface once after spreading. That initial soak locks fibers into a mat that holds through spring gusts.

Mulch Mound Pro Tip

Gunbarrel yards sit on heavy clay loam that seals up when compacted by construction traffic or foot paths. Before you spread anything, break the top four inches with a garden fork and blend in an inch of compost. That gives roots somewhere to go and stops water from pooling on the surface. Amended clay holds moisture beautifully in our 16 inch rainfall climate, so you water less all summer.

Mulch Mound Pro Tip

Timing matters in Gunbarrel because the last frost lands around May 13 and the first arrives near September 26. Spread spring mulch in mid to late May once soil has warmed, not in April when a cold blanket slows root growth. Then add a fall top dress in early October after the first frost to insulate perennial crowns through the dry, windy winter months.

Frequently Asked Questions

Click a question to see the answer

Answer

How much bulk mulch do I need for a typical Gunbarrel front bed?

One cubic yard covers about 100 square feet at three inches deep. A common Gunbarrel front bed of 300 to 400 square feet takes three to four yards. Measure length times width, divide by 100, and add ten percent for settling and for edges where wind thins the surface.

Answer

Will rock mulch work better than bark in my windy Gunbarrel yard?

Rock will not blow, so it suits exposed corners, parkways, and narrow side yards. The tradeoff is heat. Rock radiates warmth into plants and adds no organic matter to our clay loam. Use rock in high wind zones and utility strips, and keep shredded bark in shaded planting beds where soil health matters most.

Answer

Can you deliver to Gunbarrel homes with narrow driveways or alley access?

Yes. Our trucks dump in a footprint roughly ten feet wide by fifteen feet long, so a standard driveway apron works fine. If access is tight, mark your preferred spot with a tarp or cone and we will place the pile there. Plan to move material within a day or two so it does not stain concrete.

Get Started with Mulch mound Today

Gunbarrel sits northeast of Boulder where tech campuses meet open prairie, and its neighborhoods mix mature ash and honeylocust canopies with newer xeric front yards. Homeowners here often maintain HOA parkways alongside private beds, which means steady demand for consistent color and texture across large square footage. Bulk delivery of mulch, squeegee, and amended topsoil keeps those projects moving without dozens of bag runs to the store.
