Hello everyone. Hopefully you can help me. I have (2) Holly trees, approximately 8-9 feet tall, in front of my house. They have lost almost all of their leaves on the lower half of the tree, facing the house. They are losing leaves everywhere, but this is the worst place. Leaves are turning brown and falling off. Both of them are in similar (bad) shape. Some of the leaves seem to die from the tip, others seem to have the whole leave die at the same time. Please see attached photos. I have lived here for (2) years and have never fertilized them. Not sure if it is a nutrition issue or disease issue. Please help quickly!
