| after I apply crab grass control do I have to water the grass, or I do have to wait until the day before it rains to apply the crab grass control? |
| Please read and follow all of the directions on the label. The watering is intended to assure good contact between the product and the soil so it should be wetted as soon as practicable. Watering it in allows you to apply it at your convenience. But if you can apply it just before a rain then that would also work. |
