Why Landscape Fabric Fails Under Mulch & Better Weed Control

Weed fabric fails within 2–3 years: mulch decomposes into soil atop the fabric, wind-blown seeds germinate in that layer, roots penetrate fabric perforations, and pulling weeds tears the fabric up. Result: ugly, exposed plastic mess.

Better: apply pre-emergent herbicide (like Preen) before mulching, maintain 3 inches of hardwood mulch, and spot-treat breakthrough weeds. No fabric, no tear-out headaches, better soil health.
