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

Ontario's urban heat island effect raises surface temperatures in paved and hardscaped areas, which stresses plants growing near concrete and asphalt. Choosing light-colored decomposed granite or pale crushed granite for pathways and borders rather than dark river rock can reduce radiant heat absorption by several degrees. That small surface temperature difference translates to less heat stress on nearby plant roots and lower irrigation demand throughout Ontario's long, warm summers.

Mulch Mound Pro Tip

Ontario gardeners should prioritize building soil organic matter over time because the region's sandy loam tends to lose nutrients quickly through irrigation and occasional heavy rain. Incorporating two to three inches of aged compost into planting beds each fall gives soil microbes the winter months to break the material down further, resulting in a richer, more moisture-retentive soil structure by the following spring planting season.

Mulch Mound Pro Tip

Ontario properties with mature trees benefit from an extended mulch ring rather than a small circle at the base of the trunk. Spreading mulch to the edge of the tree's canopy, or drip line, covers the entire active root zone and delivers the full benefit of moisture retention and temperature regulation where roots are actually absorbing water. Most homeowners underestimate how far a mature tree's feeder roots extend and only mulch a small fraction of the root zone.

Answer

What is the best way to cool down my Ontario backyard patio area in summer?

Surrounding your Ontario patio with a border of light-colored decomposed granite rather than dark river rock or black rubber mulch can lower the immediate surface temperature by several degrees. Adding large shade trees or a shade structure above the patio, combined with drought-tolerant plants in light-colored containers, creates a layered cooling effect that makes the space far more comfortable during peak summer heat.

Answer

How thick should I apply mulch around my Ontario citrus trees?

Apply mulch three to four inches deep around your Ontario citrus trees, keeping it pulled back at least six inches from the trunk. Citrus is particularly prone to crown rot and foot rot if mulch presses against the bark. Spreading the mulch ring out to the drip line maximizes moisture retention and helps moderate the soil temperature swings that stress citrus roots in Ontario's hot summers.

Answer

Is bulk compost or bagged compost a better value for a large Ontario yard?

Bulk compost delivered by the cubic yard is almost always a better value for Ontario yards larger than two thousand square feet. Bagged compost can cost four to six times more per cubic yard when you account for the packaging markup. A single bulk delivery can cover an entire landscape renovation at a fraction of the cost, and delivery services like MulchMound make the logistics straightforward.
