I thought I knew what I was talking about until today when someone has made me second guess myself. I was told today by the "pro" at home depot that I need to start cutting grass short here in Florida to get ready for the winter and in the spring it will help the grass be healthier. I know that up north where you have snow you need to cut it short to help resist fungus and disease, but do we need to do that in Florida? I can see maybe if it's a yard full of oak trees with plent of leaves that are going to be on the ground and not get picked up, but is this necessary in Florida to cut the grass short to help it in the spring? If so how short?
