Overview

  • Professional-grade fertilizer for all seasons, but especially beneficial to apply during spring and fall because the quick-release nitrogen provides turf with immediate nutrition
  • Includes micronutrients and 2% iron for an extra-deep greening 
  • Made with extremely fine particle size for more coverage and even distribution
  • Can be reapplied every 4-6 weeks during the growing season

What Makes It Pro-Grade?

Small Particle Size

Standard consumer fertilizer granules are 60% bigger than the size of Core 12-8-12 granules. The pros prefer formulas with smaller particles because it provides more complete and uniform coverage, which boosts the product’s effectiveness.

When to Apply Core 12-8-12

Core 12-8-12 can be applied to all turf types any time it is actively growing. It contains all quick-release nitrogen so it is especially beneficial to apply it in the spring and fall or before an event when you want a quick green-up. Core 12-8-12 feeds for up to 6 weeks and can be reapplied at 4-6 week intervals.
