Q.Old Lemon Tree Trunk Cracking Up
I bought my house 45 years ago and this lemon tree was in there and as big as it is now, bears fruit twice a year. Now I noticed that the trunk is cracking up and don’t know why and what to do to prevent from spreading and or killing the tree. The tree leaves are healthy and bearing fruit. Thank you for your prompt attention Armen

Without knowing the age of the tree, you cannot know how long it has left to live. This tree is VERY aged. I would say that any cracking will be unavoidable, and expected, with an older specimen.
You can see this tree out, naturally, or you can help the structure in attempt to keep it alive for longer.
When building a brace, or putting any screws into the tree, just be sure that the screws are galvanized to avoid further damage.
Here is an article that will help you to give it the best care for the remainder of its life:
