N-Ext 9-0-1 GreeneStart Fertilizer

Multipurpose Fertilizer

N-Ext 9-0-1 GreeneStart Logo
For seeding, this product will provide excellent germination rates of seeds without risk of burning the seeds and quick rooting of new turf seedlings. It is the best product available for both re-seeding and over-seeding all types of turfgrass.
With lawns suffering from drought stress, this product will establish significant root mass and depth (drought resistance) as well as stimulate considerable soil activity which will improve soil fertility. 
  • For cool-season grass varieties, it is a recommended product for non-irrigated lawns during periods of drought stress.
  • For warm-season grass varieties, it is a recommended product for lawns where poor soil fertility is inhibiting plant health and nutrient uptake.
  • 9-0-1 is recommended for soil (non-foliar) applications on established plants, shrubs, and trees.
