Mulch is more than just a finishing touch for your landscape—it plays a vital role in maintaining soil health, regulating moisture, and preventing weed growth. But how often should you refresh your mulch to keep your yard looking its best and functioning properly? Let’s break it down.

Why Mulch Maintenance Matters

Over time, mulch breaks down, enriching the soil but losing its effectiveness in the process. Aged mulch can compact, trapping moisture and encouraging fungal growth, or it can thin out, exposing soil to weeds and temperature extremes. Regularly refreshing your mulch not only keeps your landscape aesthetically pleasing but also ensures it continues to do its job effectively.

Signs It’s Time to Refresh

  • Color Fading: Mulch loses its rich color over time, signaling that it’s breaking down.
  • Thin Layers: If your mulch layer is less than 2-3 inches thick, it’s time to add more.
  • Weeds Breaking Through: A thinning mulch layer allows weeds to sprout and disrupt your landscape.
  • Crusty Surface: A hardened surface layer can prevent water from reaching your plants’ roots.

How Often Should You Refresh Mulch?

For most Chattanooga landscapes, refreshing mulch once a year is ideal, typically in late spring or early summer. This timing replenishes the protective layer just before the peak growing season while avoiding the winter months when plants need less insulation.

Tips for Refreshing Mulch

  • Check Depth: Aim for a 2-3 inch layer. Too much mulch can suffocate roots, while too little won’t provide adequate coverage.
  • Turn the Old Layer: Before adding new mulch, fluff up the existing layer with a rake to break up compacted areas.
  • Choose the Right Mulch: Opt for high-quality organic mulch that complements your landscape design and decomposes slowly for long-lasting benefits.

By staying proactive with mulch maintenance, you’ll keep your landscape healthy, weed-free, and visually appealing year-round.
