Question: 

Which lawn care practices enhance the absorption of broadleaf herbicides?

Answer: 

To insure adequate leaf surface and herbicide absorption, don’t mow the lawn 2 to 3 days before treatment.  After treatment, allow 3 to 4 days to pass before mowing.  This allows sufficient time for the broadleaf weeds to absorb the herbicide and translocate it to their roots.  To prevent the broadleaf herbicide from being washed off the weed’s foliage, apply these materials when no rain is forecast for 24 hours.  Also, don’t irrigate treated lawns within 24 hours of the application.
