Black Shredded Mulch vs Fill Dirt
Side-by-side comparison of Black Shredded Mulch and Fill Dirt to help you choose the right gravel for your project.
Overview
Shredded hardwood mulch dyed black for a bold, modern landscape look. Rich black color makes green plants and colorful flowers stand out. Holds its color longer than brown mulch and provides the same moisture retention, weed suppression, and soil temperature regulation benefits.
Subsoil material free of organic matter, used for grading, filling, and raising elevation. Fill dirt is a lower-grade soil that lacks the nutrients of topsoil, making it ideal for structural and non-growing applications where settling must be minimized.

Sizes & Colors
Black Shredded Mulch
Shredded strips of bark and wood, typically 1-4 inches long, dyed with carbon-based black colorant. The dye is non-toxic and safe for plants and pets. Double-shredded black mulch mats together better and resists displacement.
Fill Dirt
Fine to coarse soil particles, free of organic matter like roots, grass, or leaves. Color ranges from tan to reddish-brown depending on local geology. "Clean fill" means free of debris, rocks larger than 3", and contaminants.
