The word "Fall" reflects what the leaves do this time of year. They fall off the trees and shrubs onto the ground. Here in the upper Gulf Coast of Texas we have lots of trees with leaves that don't fall. Our evergreens are just that - ever green with leaves or needles that don't fall. And we have live oaks that hold their leaves all winter long only to drop them in the spring when they are getting ready for new growth.
Our pecan trees, however, really do fall in the fall. They start to lose their leaves this time of year and also lose small limbs. We don't rake leaves but we do spend lots of time picking up the small limbs with their attached leaves. The pecan has fairly brittle limbs and with our increased winds happening right now, lots of these small limb are broken and end up on the ground.
We pick them up.
