So I noticed over the winter, there are about 4 branches on my tree with black knot. I'm reading that they are very contagious and eventually lead to the tree dying if untreated. However, I'm reading that you can prune it away to mitigate it.
I don't want to incorrectly prune branches off and hurt the tree and end up killing parts of it. Should this be done professionally? Has anyone DIY'd this before?
For reference, this is what black knot looks like:
Not my tree, this one is a little more severe, but you get the idea.
