Question: 

Do I need to remove the leaves on my lawn?

Answer: 

Turfgrass plants utilize light, water, and nutrients to manufacture food.  In fall, lawn areas beneath large trees are often completely covered with leaves.  The leaf debris prevents the turfgrass plants from manufacturing and storing food prior to winter.  A thick layer of leaves (little or no grass is visible) will need to be raked up and removed.  It’s possible to deal with a thin layer of leaves (areas of grass are clearly visible) by chopping them up with a mulching mower.  After mowing, little leaf debris should be visible.
