When a tree is  hit by lightning, the damage can be severe in some cases and incidental in others.  It’s not always easy to tell how badly the tree was injured just by looking at it. What do you need to do after the damage occurs?  Walter Reeves, the Georgia Gardener, discusses this in a Q&A column at https://www.walterreeves.com/gardening-q-and-a/lightning-damage/. Fortunately, unless the tree is already down, you probably have time to get it looked at by a certified arborist before making any decisions.
