How to Apply Casoron Weedkiller
- 1). Allow any wanted plants to grow to maturity with established roots. Allow any transplanted crops to grow for four weeks before applying Casoron.
- 2). Clear any weeds by hand or with cultivating equipment in early spring or late fall.
- 3). Spread granules evenly over the soil. According to Chemtura, apply 1.5 to 2.5 ounces of Casoron per 40 square feet. The Arnold Arboretum recommends applying 1 ounce per 20 square feet.
- 4). Irrigate with 1/2 to 1 inch of water to allow the granules to dissolve. Alternatively, cover the granules with wet mulch.
- 5). Repeat each year as needed.
