Repairing Arborvitae - Knowledgebase Question

We had to trim large broken branches from our bish. The branch snapped off leaving a large exposed part of the main trunk, which appears to be hollow at the center. What if anything should we do to protect the main tree trunk?

There's really nothing more you need to do. While there are wound dressings available in garden centers, they tend to slow the healing process so don't use them. Instead, just leave your arborvitae alone now that you've removed the broken branches. It will seal off the injury from the inside and eventually you'll see it callous over the wound. Depending upon where the wound is, you may want to prune the main stem back slightly below the wound so you can make a clean cut that angles down. This way rainwater and debris won't collect in the hollow. If this is not possible, just leave it as it is and give your arborvitae a chance to heal the wound on its own. Best wishes with your arborvitae!
