Our weed control service offers control of Broadleaf weeds which are commonly found in residential lawns. It works best when combined with one of our lawn care packages.  A healthy lawn competes against weeds better than an unhealthy lawn, therefore weed control starts with a lawn care package and continues with this weed control service. 

For customers who sign up in the spring, we offer 3x applications targeting the weeds on your lawn.  
  1. Fiesta Application #1 - You can expect that the first application to kill effected weeds down to the root within 24-72 hours.
    • Weeds are expected to regrow from the root within 7-28 days.  
  2. Fiesta Application #2 - The second application will take care of these regrown weeds, killing them back down to the root.  
    • At this point the weeds will be entering the dormant summer period
  3. Fiesta Application #3 - After the heat of the summer breaks in September, we'll begin the third application.  
    • This will take care of weeds which have survived the summer or have recently popped up.  



Here is a list of the weeds which Fiesta is able to control:
