The added Iron content enhances turf color. Its high levels of Potassium help to harden turf during stressful conditions in summer and autumn conditions. Additionally, its Phosphate free formulation assists in managing Phosphorous buildup in the soil. It is particularly suited for use on fine turf areas.

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.
