LESCO 5-0-20 Spar-TECH™ MOP BIO Fertilizer

Low nitrogen. High potassium. Built for heat, drought, and seasonal transitions.

LESCO® 5-0-20 Spar-TECH™ MOP BIO Fertilizer is a professional-grade stress blend designed to strengthen turf without forcing excessive top growth. With 20% soluble potash, added iron, and biosolids for organic support, this formula helps lawns handle heat, drought, traffic, and seasonal change with improved resilience and color.

This is an ideal fertilizer when nitrogen demand is lower but potassium becomes critical for root strength, cellular structure, and overall turf durability.
