Dwarf Japanese Maple - Crack where branch meets trunk.
Hello. I just noticed that my Dwarf Japanese Maple has a substantial crack in one of the main branches where it meets the trunk. I've attached a photo, and was hoping that some wonderful tree loving soul could offer some advice on how I can save this branch that amounts to 1/3 of the tree. If I lose this branch, the tree would be irreparably lopsided. Please help! Other than this crack, that branch seems to be healthy and happy. The tree is all of 3 feet tall, and is probably about 3 1/2 years old. I suspect that this crack has been there for some time. Would a small bolt with a few washers be the answer?
Thanks in advance for any advice you may have.
