I have an Oriental Arborvitae (platycladus orientalis) pine tree that is about 25 years old. Its leaves started getting brown last Fall so we gave it a severe haircut. All the new growth also turning brown. I placed fertilizer spikes hoping that it was lack of fertilization. DGs from the Beginning Gardening Forum thought it could be too much water, cold weather or a fungus. Last month, I cut down somewhat on watering the tree and applied a fungicide. New growth comes out a beautiful green but turns brown as soon as it shows up and a lot of the twigs look like they are dead. I do not know what else to do --is my tree dying? I am thinking of cutting is down to about 3 feet and see what happens. Any suggestions will be greatly appreciated. SL
