Bermuda Grass (Devil Grass) Invasion: Physical Barriers Only

Cynodon dactylon—Bermuda grass, couch grass, devil grass—is a deep-rooted perennial creeper that laughs at herbicides. Organic solution: exclusion.

The Weed Fabric System

Black landscape fabric (Home Depot) over prepared beds—lets air/water/fertilizer through.
Cover with bark mulch.
Critical: Deep perimeter barrier (metal edging, buried 12"+) to stop rhizomes creeping under fabric.

Glyphosate kills top growth but misses deep rhizomes. Re-sprouts within weeks. Fabric + barrier is permanent if maintained.

Contact your county Horticultural Extension Service—they've seen this exact battle hundreds of times.
