Re: When to prune Norway Spruce in lower Michigan
Thank you. Your answer helps me but I do have another question. I have been reading about a fungus that Norways are prone to and sometimes worsens after pruning. It is cytospora. Do you know anything about it?
Also, when do I prune dead wood off river birches? To me dead is dead and should come off but I don’t know if the borers agree with me. Don’t want to issue an invitation to them.
