Product Overview

Suståne 4-6-4 is a high-phosphorus organic fertilizer specifically formulated for new turf establishment. Whether you are seeding, sodding, or installing sprigs, 4-6-4 provides the critical phosphorus needed for rapid root development and carbohydrate storage. Unlike synthetic starters that can leach easily, the nutrients in Suståne are bound in a complex organic matrix that releases slowly as the young plants need them. It is also enriched with diverse microbes and humic acids to create the perfect soil environment for young turf to thrive.
