Why Sweetgum Fall Color Fades Some Years

Weather, Not Management, Drives Autumn Color Intensity

Color change triggered by night length, not temperature. Brilliant reds need warm sunny days + cool (not freezing) nights to trap sugars and produce anthocyanins. Drought, wet springs, warm falls reduce intensity. No fertilizer or treatment changes this; it's annual weather variation.
