Jacks Prof Plant Starter 9-45-15 25Lb — Single Unit

Jack's Professional® 9-45-15 Plant Starter Fertilizer is a high-phosphorus formula designed to encourage rapid root establishment following transplanting into cells, beds, containers, or field production areas. The nutrient ratio prioritizes root development before excessive shoot growth, helping young plants become established and recover from transplant stress. It can also be used to supplement or correct low-phosphorus conditions, particularly in outdoor production systems.
