|my tree split,should i nail it ,tape it,or cut the branch off|
|You can't repair a branch; the best thing to do is prune it back to it's main source, probably the trunk. To make a proper pruning cut, do not cut the branch off flush with the trunk. Cut just beyond the branch collar, a slightly raised area where the branch and trunk meet. At this point, the tree's own meristematic tissue will seal the pruning wound. It's the tree's natural healing system.
For a large heavy branch, the proper way to prune is to make three separate cuts. The first two are to eliminate the weight of the branch and prevent it from tearing bark down the trunk of the tree, which is unsightly and also allows disease/pests an entry. 1. Start with an undercut (cutting from th underside of the branch upwards) about 8-10 inches from the trunk, but cut only about half way through the branch. This prevents splitting and stripping of bark down into the trunk. 2. About 2-4 inches further past the undercut, cut the branch off (from the top to bottom). 3. Now that the weight of the heavy branch is off, make a clean, smooth cut just past the branch collar.
Don't apply any sealants to pruning cuts. Research shows that sealants will not prevent decay and actually interfere with the tree's healing ability. If we prune properly, the tree can take care of itself.
