Rapid vegetative growth of forest seedlings occurs between the 4th and 16th weeks of growth. 20-8-20 should be used on a constant feed basis to encourage good top growth. This formulation contains four times more iron than most Plant-Prod fertilizers, lower phosphorus and added magnesium. It should be used for the majority of the growing season, once seedlings have a well established root system.
