Black Shredded Mulch vs Compost

Side-by-side comparison of Black Shredded Mulch and Compost to help you choose the right gravel for your project.

Overview

Black Shredded Mulch

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.

Compost

Decomposed organic matter used as a soil amendment to improve soil structure, fertility, and water retention. Quality compost is dark, crumbly, and earthy-smelling. It adds beneficial microorganisms and nutrients that support healthy plant growth and improve poor soils.

Common Uses

Black Shredded Mulch

  • Landscape beds
  • Tree rings
  • Garden borders
  • Foundation plantings
  • Commercial landscaping
  • Contrast beds

Compost

  • Soil amendment
  • Garden beds
  • Lawn top-dressing
  • Raised beds

  • Slightly more expensive than undyed mulch

Compost

  • + Dramatically improves soil structure and fertility
  • + Increases water retention in sandy soils
  • + Improves drainage in clay soils
  • + Adds beneficial microorganisms
  • + Reduces need for chemical fertilizers
  • Quality and composition vary widely between sources
  • Can be odorous when fresh
  • May contain weed seeds if not fully composted

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.

Compost

Fine, crumbly texture when fully decomposed. Dark brown to black color. Should smell earthy, not sour or ammonia-like. Screened compost has been filtered to remove large uncomposted pieces. Mushroom compost is a byproduct of mushroom farming and is particularly nutrient-rich.
