Garden Myth-Busting for Extension Educators: The Science Behind the Use of Arborist Wood Chips as Landscape Mulches

Mulches can reduce soil water loss in gardens and landscapes. Not all mulches are created equal, however, and some mulches can damage both soil and plant health. This literature review will focus on arborist wood chip (AWC) mulches – arguably the most beneficial landscape mulch – and address common misconceptions about this mulch material. We also provide science-based recommendations for using AWC mulches to enhance the resiliency of managed landscapes.
