5-0-15 Life Support Granular Lawn Fertilizer – Soil & Turf Recovery

Life Support 5-0-15 Lawn Fertilizer for Heat, Drought & Stress Recovery

Life Support 5-0-15 is a potassium-focused lawn fertilizer and soil amendment designed to help turfgrass withstand and recover from environmental stress such as heat, drought, and seasonal pressure. This formula supports lawn health without forcing excessive top growth, making it ideal for summer applications and stress-recovery periods.

With 15% potassium from sulfate of potash, Life Support improves water regulation and cellular strength in grass plants. Magnesium supports essential plant functions, while a biostimulant blend of humic acid, sea kelp extract, and plant protein hydrolysates enhances nutrient uptake, root development, and soil biology.

Life Support is non-staining, safe for all major grass types, and fits seamlessly into a balanced fertility program focused on long-term turf resilience rather than short-term growth spikes.
