Grass Growth Inhibitors for Roadside Signs: Non-Chemical Options

Corn gluten meal feeds grass—it won’t inhibit growth. Non-chemical options for grass suppression around signs:

• Cut grass short, cover with landscape fabric, top with gravel/stones.
• Spray pickling vinegar (20% acetic acid) on hot day—kills all vegetation.
• Dig area, mix cement into soil, water—forms durable crust for foot traffic.
• Pour waste cooking oil on soil—eventually waterproofs, prevents growth (not for drainage areas).

Avoid grass-killer herbicides—they leach to water table. Physical barriers or vinegar are safer for village use.
