What can I do if I applied Preen Garden Weed Preventer Plus Fertilizer to my lawn or a plant not listed on the label?
If you have used Preen Garden Weed Preventer Plus Fertilizer on your lawn or with a plant not listed on the label, apply activated charcoal at a rate of lb. per 100 square feet. This charcoal is commonly used in filters of fish tanks and can be found at a local pet supply store. Lightly work the charcoal into the surface of the soil and thoroughly water it in. Repeat the watering schedule for 3 days.
