    When to Apply:  

    • Apply in the spring prior to germination of crabgrass and other grassy weeds. 
    • Best time to apply fertilizer is from mid-February through mid-April depending on region.
    • Spread product a day or two after mowing and when the lawn is dry. 
    • Safe to use on newly seeded or sodded lawns.


    • Use a rotary or drop lawn spreader.
    • Check that the spreader opening at the bottom of the hopper is closed.  
    • To select the proper spreader setting see the Spreader Settings section in the accordion below. 
    • Push the lever forward only when ready to spread.
    • Apply fertilizer around the perimeter of the lawn to establish a turning area. Then run the spreader back and forth within the area outlined by your first perimeter application. Always allow an overlap to avoid gaps in coverage. 


    • Sweep any excess granules off of hard surfaces and back onto the lawn.
    • Thoroughly irrigate the treated area after application for best results. About 1 ½ inches of water per week is sufficient between rainfall and irrigation, but not to the point of run-off. 
    • Once watered, wait a day to mow the lawn allowing the product time to activate.
