Colors Nutritional For Trees
Research shows that fall's bright red leaves deliver more nutrients to trees than if they were not so colored.
Trees in nutrient-poor soil produced more red pigment, backing a 2003 discovery that blocking red pigment production makes leaves ultra-sensitive to sunlight, causing less nutrients to be delivered to the plant.
This means that when the soil is poor, making the red pigment keeps those leaves working longer.
