@jckeystone12 No one can say, w/o benefit of a soil test, that a plant shouldn't be fertilized. If there is ANY deficiency of a nutrient essential to normal growth, the plant would definitely benefit from using fertilizer to eliminate the deficiency.
Any fertilizer applied to plants in the landscape w/o benefit of a soil analysis, whether it is a "balanced fertilizer" applied as a shotgun approach or an element/compound applied specifically meant to target a perceived deficiency of one or two nutrients, is the result of no more than a SWAG.
