How many days before I notice the weeds dying after applying Fertilome Weed-Out Lawn Weed Killer with Trimec...
You should notice that weeds are starting to yellow or die about two weeks after the application of Fertilome Weed Out. Spray at any time when weeds are growing. For best results, apply in Spring when weeds are small and growing rapidly. Apply in Fall to remove late germinating weeds.
