Mulching is one of the best things you can do for your landscape. It conserves moisture, suppresses weeds, and enhances curb appeal. But when is the best time to mulch? What type should you choose? Here are some tips about mulching your property in the Chapel Hill, NC area.
Best Time to Install Mulch
The ideal time to mulch is in early spring (March-April) and late fall (October-November). Spring mulching helps retain moisture before summer heat arrives, while fall mulching insulates roots from winter cold.
Types of Mulch & How Long They Last
Organic Mulches (Break Down Over Time, Enrich Soil)
- Hardwood Mulch – Lasts 1-2 years; ideal for trees, shrubs, and flower beds.
- Pine Bark Mulch – Lasts 1-3 years; lightweight, good for moisture retention.
- Pine Straw – Lasts 6-12 months; excellent for acid-loving plants like azaleas and camellias.
- Wood Chips – Lasts 2-3 years; great for naturalized areas but may take nitrogen from the soil initially.
Inorganic Mulches (Do Not Decompose)
- Rubber Mulch – Lasts 10+ years; good for playgrounds, but can retain heat.
- Stone or Gravel – Lasts indefinitely; excellent for drainage but doesn’t improve soil health.
Mulch Colors & Their Effects
- Black Mulch – Bold contrast; absorbs heat (not ideal for hot areas).
- Brown Mulch – Natural look; blends well with most landscapes.
- Red Mulch – Vibrant; commonly used for decorative appeal.
- Natural (undyed) – Classic and safest for plant health.
Should You Remove Old Mulch?
If the old mulch is less than 2 inches thick and not compacted, simply refresh it by adding a thin layer. However, if it has built up over time or developed mold/fungus, remove it before applying new mulch.
How Thick Should Mulch Be?
For most applications, aim for 2-3 inches of mulch. Too much can suffocate plant roots, while too little won’t provide benefits.
