Using Sugar to Suppress Invasive Bermuda/Wiregrass and Why Hand-Broadcasting Works Best

Sugar's Role

Sugar enriches soil microbes → improved soil structure/fertility → weeds (crabgrass, johnsongrass, Bermuda) cannot thrive. Wild violets and nasturtiums also disappear in rich soil.

Bermuda/Wiregrass Specifics

• If it's a weed grass, sugar will suppress it over time.
• Charlotte's experience: St. Augustine plugs crowded out Bermuda in 8 years with only sugar.
• Hand-pull Bermuda to base, dig out root crown for faster removal.
• Bahia may not outcompete Bermuda like St. Augustine does.

Application Method

Hand-broadcast in sweeping arcs. 1 lb/250 sq ft. Even coverage not critical—sugar won't burn. Spreader settings unknown; hand is simpler and more precise.
