Brown Shredded Mulch vs Fill Dirt
Side-by-side comparison of Brown Shredded Mulch and Fill Dirt to help you choose the right gravel for your project.
Overview
Shredded bark and wood from trees like oak, hickory, and maple. Retains moisture, suppresses weeds, and regulates soil temperature. Decomposes slowly over time, adding organic matter to the soil. Adds a natural, finished look to landscape beds.
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.

Pros & Cons
Brown Shredded Mulch
- + Retains soil moisture reducing watering
- + Suppresses weed growth naturally
- + Insulates soil temperature
- + Decomposes to enrich soil over time
- + Attractive natural brown color
- − Needs replenishing every 1-2 years as it decomposes
- − Can attract termites if placed against structures
- − May temporarily rob nitrogen from soil as it breaks down
- − Floats and washes away in heavy rain
- − Can develop mold in overly wet conditions
Fill Dirt
- + Very affordable — often cheapest material available
- + Compacts firmly for structural support
- + Does not decompose or settle like organic soil
- + Widely available from construction sites
- + Ideal base under gravel or concrete
- − Not suitable for growing plants
- − Must be free of debris and contaminants
- − May contain clay that drains poorly
- − Needs compaction in layers for stability
- − Quality varies widely between sources
Cost Comparison

| Per cubic yard | $25 – $45 | $8 – $25 |
Sizes & Colors
Brown Shredded Mulch
Shredded strips of bark and wood, typically 1-4 inches long. Natural brown color that fades to gray over time. Double-shredded mulch is finer and mats together better, resisting wind and rain 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.
