Mulching

Proper Mulching for Tree Health and Root Protection

Mulching can reduce environmental stress by providing trees with a stable root environment that is cooler and contains more moisture than the surrounding soil. Mulch can also prevent mechanical damage by keeping machines such as lawn mowers and string trimmers away from the tree’s base. Further, mulch reduces competition from surrounding weeds and turf.

Best Practices for Mulching Around Trees

To be most effective in all of these functions, we place mulch 2 to 4 inches deep and cover the entire root system, which may be as far as 2 or 3 times the diameter of the branch spread of the tree. If the area and activities happening around the tree do not permit the entire area to be mulched, we mulch as much of the area under the drip line of the tree as possible. When placing mulch, we take care not to cover the actual trunk of the tree. This mulch-free area, 1 to 2 inches wide at the base, is sufficient to avoid moist bark conditions and prevent trunk decay.

Use Organic Mulch for Healthy Root Growth

An organic mulch layer 2 to 4 inches deep of loosely packed shredded leaves, pine straw, peat moss, or composted wood chips is adequate. We do not use plastic because it interferes with the exchange of gases between soil and air, which inhibits root growth. Thicker mulch layers, 5 to 6 inches deep or greater, may also inhibit gas exchange.

🌿 Why Mulching is Essential for Healthy Trees

Mulching isn’t just about aesthetics — it plays a crucial role in supporting tree health by improving soil conditions and protecting roots.

Benefits of Proper Mulching:

  • Retains soil moisture, reducing the need for frequent watering

  • Moderates soil temperature, keeping roots cool in summer and warm in winter

  • Suppresses weed growth and minimizes lawnmower damage

  • Gradually adds nutrients to the soil as it breaks down

🚫 Avoid Common Mulching Mistakes Around Trees

While mulching is beneficial, incorrect application can cause more harm than good. Knowing where and how to apply it makes all the difference. 

Best Mulching Practices:

  • Apply mulch 2 to 4 inches deep

  • Extend mulch to cover as much of the root zone as possible (up to 2–3x the tree’s branch spread)

  • Keep a 1 to 2 inch mulch-free space around the tree trunk to prevent decay

  • Use organic mulch like bark, wood chips, or compost for best results
