Q.Why Don’t Willow Tree Branches Touch The Ground?
Hopefully this is not too random, but I was curious as to whether you’d know the answer to this question. I’ve noticed that with the majority of willow trees, the weeping branches always seem to fall to the same height without ever touching the ground. Is there a reason for this?

Most likely the owner is pruning them to keep them off the ground, which can be hazardous to walk under or see around while driving. If not pruned, they would continue growing to the ground.
