How to Apply

Apply to dry foliage and irrigate after 1-2 days if no rain has fallen. Irrigation will aid dispersion and minimise any risk of mower pick-up on close mown surfaces. Try avoiding applications during frosty or drought conditions.

Delay verti-cutting and/or grooming for 3 days after application to allow the granules to disperse.

Nitrogen release is significantly slowed down when soil temperatures are less than 10&deg: Watering-in after application will minimize foot printing risk.
