Key points
  • Ideal for use during over-seeding or laying new turf
  • High phosphorous content promotes good rooting and establishment
  • Slow release nutrient sources minimise salt levels to enhance germination
  • Nutrient release pattern meets new turf / seed demands
Directions for use
  • 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.
  • Avoid 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 10ºC.
