Hello,
We had 9 white spruce trees planted 13 years ago on raised berms. They have gotten quite tall, probably 20-25 feet but are suffering year after year of what looks like a needle cast disease. My question is, what can be done? Do trees ever recover on their own? I would hate to lose them as we planted them as a natural privacy fence. Thank you.
