Green Shocker 7-1-2 is an all quick-release lawn fertilizer containing iron and humic acid. This means that nutrients are delivered to the lawn immediately, rather than slowly reaching the turf over a period of 6 to 8 weeks like a typical slow-release fertilizer. Green Shocker 7-1-2 is safe for all turf types and should be applied to turf that is actively growing. The result will be noticeably greener grass as soon as 72 hours after application and lasting as long as 2-3 weeks. The particle size pf Green Shocker is extremely small for precise coverage. Each Green Shocker prill includes The Andersons DG Technology which allows each particle to disperse into thousands of micro particles after coming into contact with rainfall or irrigation. Green Shocker 7-1-2 is the perfect supplemental boost for greening up your lawn before a party and for those interested in spoon feeding applications.
