DO NOT put fabric under mulch
What happens here
The video highlights that placing weed fabric underneath mulch, especially around trees, is ineffective for weed control. Mulch inherently breaks down into organic matter, effectively becoming "pre-dirt" or soil. This newly formed soil layer sits above the fabric, providing a suitable environment for weeds to germinate and grow, creating a "fabric Oreo" effect where weeds thrive despite the barrier.
Goal: Understand why weed fabric is not recommended under mulch.
