Stress Blend contains 7% nitrogen, with half in slow-release form and half immediately available. This provides steady nutrition for stressed turf without forcing aggressive top growth. A stressed lawn still needs feeding, and slow-release nitrogen supports recovery in a safer, more controlled way.

With 20% potassium, Stress Blend excels at helping turf manage stress by improving water uptake and retention. Potassium helps keep plant cells hydrated and functioning during heat, drought, and other environmental challenges.

Stress Blend also includes a full micronutrient package, including magnesium, boron, copper, manganese, molybdenum, and zinc to support overall plant health. Added iron delivers a noticeable color pop without pushing excessive growth.

Bio-Nite™ is included in every bag to feed beneficial soil microbes and support soil health with each application.
