Black Shredded Mulch (Gorilla Hair Mulch)

Our Black Shredded Mulch, commonly known as Gorilla Hair Mulch, is a premium, finely shredded bark mulch designed for maximum coverage, moisture retention, and a clean, modern landscape look. This dark, fibrous mulch interlocks as it settles, creating a dense surface layer that resists wind, runoff, and displacement—making it ideal for residential gardens, slopes, pathways, and commercial landscapes throughout the Bay Area.
 
Sourced from natural bark and processed into long, stringy fibers, this mulch provides a rich black finish that dramatically enhances plant contrast while helping suppress weeds and regulate soil temperature. It’s a good choice for homeowners, landscapers, and contractors looking for low-maintenance, long-lasting mulch delivered locally to job sites across San Rafael, Mill Valley, Novato, Petaluma, Santa Rosa, Walnut Creek, Concord, San Francisco, and surrounding cities.
 
Black Shredded Mulch (Gorilla Hair Mulch) is engineered for both performance and appearance, making it one of the most versatile mulches we offer for Bay Area landscapes. Its long, fibrous strands naturally knit together after installation, forming a stable surface layer that stays in place better than chipped or nugget-style mulches.
 
Common Uses
Landscape Beds & Garden Borders
Creates a bold, high-contrast backdrop that makes plants, shrubs, and trees stand out—especially popular in modern and contemporary designs throughout Marin and San Francisco.
 
Slopes & Hillsides
The interlocking fibers help reduce erosion and mulch migration, making this a preferred choice for sloped properties in Mill Valley, Sausalito, and hillside neighborhoods.
 
Tree Rings & Planter Areas
Helps retain moisture around root zones while reducing soil compaction and surface crusting.
 
Commercial & HOA Landscapes
 
Clean appearance, longer lifespan, and reduced maintenance make it ideal for apartment complexes, office parks, wineries, and retail centers across Sonoma and Contra Costa counties.
 
Pathway Edges & Decorative Ground Cover
 
Works well alongside gravel, pavers, and stepping stones to soften hardscape transitions.
 
Why Contractors & Homeowners Choose It
Excellent weed suppression
Strong wind and slope resistance
Slower breakdown compared to wood chips
Rich black color that complements stone, concrete, and greenery
This mulch is especially well-suited for coastal and inland microclimates, performing consistently from foggy Marin coastlines to warmer inland areas like Walnut Creek and Concord.
 
Coverage, Depth & Installation Tips
Installing Black Shredded Mulch (Gorilla Hair Mulch) at the proper depth is key to getting the best performance, appearance, and longevity—especially in Bay Area climates where wind, slopes, and dry summers are common.
 
Recommended Installation Depth
2–3 inches → Decorative beds, tree rings, and planter areas
3–4 inches → Weed suppression, moisture retention, and sloped areas
Avoid over-applying. Depths greater than 4 inches can limit airflow and water penetration.
 
Coverage Guide (Approximate)
1 cubic yard covers:
~160–180 sq ft at 2 inches deep
~110–120 sq ft at 3 inches deep
This high coverage efficiency is one reason Gorilla Hair Mulch is popular for large residential properties and commercial landscapes across Marin, Sonoma, and Contra Costa counties.
