Weeping willows are great trees to have.  They are indigenous to the swamplands and love water.  These trees if planted in the right areas can become very nice trees that your kids will love to play on.  They are very easy to identify.  They are the only tree in the area that have large vine like limbs that reach to the ground. 
Weeping willows only get one disease that will kill them off.  This usually happens when a tree is planted in the wrong areas.  Iron Chlorosis is a very serious problem among new willow trees.  You will notice the leaves turning yellow in the spring or summer seasons. Then the tree will start to die off.
