So Much Mulch!


The Spark:
Every autumn, the leaves of deciduous trees fall to the ground.  The word deciduous means "falling down."  If the trees did not drop their leaves in the autumn, they would dry out during the winter and die.  Deciduous trees such as maple, hickory and oak have broad, flat leaves that soak up a lot of sun.  In the spring and summer months, when trees are making food, the leaves are filled with green colouring.  In autumn, when the trees not making food, the green colouring breaks down and you can see the yellow and orange colours  underneath.  These colours were there all along!

Leaves on the ground are called leaf "litter."  They are viewed as messy and they usually smother plants growing under deciduous trees.  But how sensible is it to plant something where you know it is going to be smothered by falling leaves every autumn?  If you avoid planting anything under deciduous trees, after a rainy day in autumn, the leaves will become matted and stay in place.  Leaf litter performs a valuable service for trees and wildlife.  The leaves decay, and numerous organisms feed upon them, making their nutrients available to the tree from which they fell.  Nature constantly recycles matter and wastes nothing.  If you must rake up leaves, add them to a compost pile.
