Arborist wood chips form a porous, layered blanket over the soil surface. This layer slows evaporation by shielding the soil from direct sun and wind exposure. During rainfall or irrigation, the chips absorb and hold water, releasing it gradually into the soil below.
Why this is important:
Improves Soil Health Over Time
Unlike bark mulch, arborist chips contain a mix of wood, leaves, and small twigs. This diversity feeds beneficial soil organisms such as fungi, bacteria, and earthworms. As decomposition occurs slowly at the soil surface, organic matter is incorporated naturally without disturbing root systems.
Why this is important:
Effective Weed Suppression
A thick layer of arborist wood chips blocks sunlight from reaching weed seeds, stopping germination before it starts. Existing weeds are weakened as they struggle to push through the dense mulch layer, making them easier to remove.
Why this is important:
Protects Roots & Regulates Soil Temperature
Wood chips act as natural insulation for the soil. In summer, they reduce heat penetration that can damage shallow roots. In winter, they buffer against freezing temperatures and prevent repeated freeze–thaw cycles that can heave roots out of the ground.
Why this is important:
Cost-Effective & Environmentally Sustainable
Arborist wood chips are often available at low or no cost directly from tree service companies. Using them recycles tree waste locally rather than sending it to landfills. Over time, they reduce the need for fertilizers, irrigation, and weed control products.
