My 40 year-old Redbud has large openings facing upward in the bark of two of its horizontal branches. These are large branches that are still structurally strong and produce lots of buds in the spring. Rain and melted snow water can collect in the openings and will freeze in the winter, possibly splitting the branch. What can I use to either (1) fill these holes with some material to make a permanent or semi-permanent repair, or (2) wrap the branches at these locations to repel water over the winter?
