When to prune River Birch
I bought my home last spring and there is a 5-6 year old River Birch in front. I doubt that it has ever been pruned and I would estimate that it is about 20 feet tall.
It has a couple of crazy branches (one crossing branch and another that goes straight out horizontally, unlike any of the others) that really need to be pruned out to get the tree in balance.
I'm looking for the best time to prune these branches and how far from the trunk they should be cut. Should I also use a wound sealer after making the cut?
Any help would be greatly appreciated. Thanks in advance.
