Using commas in the right place.
Zora's lemon tree produces too much fruit. She gives them away therefore, to her friends and neighbors.
Another fundamental corrections to add:
Your second sentence begins with "She gives them..." Somehow, you've made a singular fruit into multiple fruit. Fruit, as you've used it, is a singular word that represents a plural group. In your first sentence, you've used the singular group word, "fruit," instead of the plural word for the individual items, "lemons." Yet in the second sentence, you've used a pronoun that doesn't match your previous noun, "fruit," as you've used it.
If you had said, "Zora's lemon tree produces too many lemons. She gives them away...," the second sentence would be correct. Or, it could be correct (but not as strong) if you had said, "Zora's lemon tree produces too many fruit. She gives them away..."
Your choice disagrees with itself. "Too much fruit" applies the word fruit in the singular. "Them" represents the "too much fruit." That pronoun fails here.
As for your question, I would suggest removing the word "therefore" entirely. Then you would have no need for commas.
