Alternative to Pesticides for Weeds

  • Add a couple of drops of liquid soap to white vinegar to help it adhere to the plant
  • Spray on a dry, sunny day
    • Optional: add salt to prevent weeds from coming back. Salt will also inhibit other plants from growing, so only add salt where you know you never want anything to grow (ex: walkway, crack in sidewalk, etc.).

Boiling Water

Precautionary Principle - When to Use Pesticides

Emergency use of pesticides is the only acceptable use of pesticides. To optimize public safety and environmental quality, the use of all pesticides-even the Organic and Least Toxic certified products-should be minimized and treated as a last resort rather than a step of routine maintenance.
