Jonathan Greens Green-Up Lawn Food is a quick, deep greening fertilizer that can be used on all types of turfgrass and will feed the lawn for up to three months. The polymer-coated nitrogen in this product provides a slow and steady food release, preventing a surge of grass growth in the early spring, which reduces grass clippings when mowing. Green-Up is the best fertilizer to use in the early spring if crabgrass is not present.
Apply Green-Up Lawn Food spring through fall when grass is actively growing on established lawns.Apply to a dry lawn before a rain or water in after application. If the lawn is under stress from lack of rainfall, disease or heat, or if air temperatures are 85° or higher, do not apply this product, as turf injury may occur.
