Directions for use

Apply to dry foliage. Water if no rain has fallen 1 – 2 days after applications. Irrigation will aid in dispersion and limit risk of mower pick-up on low cut surfaces. Watering-in after application will limit footprints. Avoid applications in frosty and drought conditions.

Delay any vertical cutting a/o grooming until 3 days after application; allows granules to properly disperse. The Nitrogen release is significantly lessened when soil temperatures are below 10ºC.

If spilled on pavement, concrete, etc, make sure to brush off immediately as the product can cause discoloration.
