Nutsedge in Boxwood Hedge: Go Organic to Suppress Weeds

Nutsedge invading a new boxwood hedge in NC indicates poor soil. Chemical herbicides risk damaging boxwoods. Organic solution: build soil health so weeds can’t thrive.

Apply sugar or dry molasses (1 lb/250 sq ft) and water deeply. Feed beneficial microbes that enrich soil. Weeds like nutsedge prefer poor soil; rich, biologically active soil suppresses them. Avoid all chemicals—they kill microbes and create dependency.

Over 3–4 years, weeds diminish. Use baking soda for fungus, deep watering, high mowing. Resource: DirtDoctor.com.
