Is there anything I should do to help fix a split on my tree trunk?

I have a 20-year-old shade tree that developed a split on its trunk last winter. It looks better this spring, but is there anything I should be doing to it?

It sounds as though your tree has a frost crack. Frost cracks develop from the expansion and contraction of bark and wood during wide temperature fluctuations in winter. A weakened section of the bark splits open from the stress. The sudden break is often accompanied by a loud noise like a gunshot. Cracks usually close up during the growing season, but they may remain partially open. If a large split fails to close, consult an arborist to install a rod or bolt to hold it together.
