SierraformGT Pre-Seeder 18-22-05 (6-8 weeks) contains both slow release Nitrogen and slow release Potassium, along with conventional release NPK in a single compound micro-granule.

SierraformGT Pre-Seeder is ideal during over-seeding period or when laying new turf. It comes equipped with Everris’ patented MU2 and SilK coating technologies. The high Phosphorous levels encourage rooting and establishment 

Pre-Seeder's slow-release nutrient resources minimize salt levels to enhance germination. Its nutrient release pattern is designed to meet new turf / seed requirements.

Product advantages

  • Ideal during over-seeding periods or when laying new turf
  • Phosphorous content encourages good rooting and establishment
  • Minimizes salt levels to enhance germination
  • Nutrient release pattern meets new turf / seed demands

Apply to dry foliage. Water in if no rain falls within 1-2 days after application. Irrigation will aid 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 and/or grooming until 3 days after application; allows the granules to properly disperse. The Nitrogen release is significantly reduced when soil temperatures are below 10ºC.

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