Why do leaves change color in autumn?
Fall leaves are perfect for compost or mulch in the garden. 
  • To support the leaf-viewing tourist industry
  • Shorter and cooler days make deciduous trees lose green chlorophyll, revealing other colors
  • Chemicals in the air damage the leaves, making them turn brown
  • The wizards that keep the leaves green in the summer go on vacation
