On our front lawn we have a clumping birch. It was planted 3 summers ago and has grown into a beautiful tree. This spring when it's leaves opened a lot of them looked like they were sick. We watered the tree and trimmed off the lower branches to help the upper ones.
It still looks like part of it is dying. There are a lot of ants on the tree. Could that kill it? Is there some sort of fertilizer to give it? I would hate to see my gorgeous tree die. Not to mention the cost to cut it down.
Any advice would be most welcome!
