I just cut down a crab apple tree in my own yard. It was a pretty mature tree and has had that stupid black spot disease for several years. We want to replace that tree in the front yard, but I'm not sure I want another crab apple. I don't want another tree that can get that blight and the leaf loss issue. But I do want another tree that doesn't grow really big, kinda stays a medium size, and will provide a little bit of shade in my front yard. So I need recommendations. Also, after that tree being infected with that fungus for several years, I need something that won't catch the fungus from anything that might be lingering in the yard. Whereas I've done lawn care for 23 years, I have no clue about trees and need help finding a good replacement. I was thinking about a red japanese maple. Any recommendations would be appreciated.
