The tree

Our clementine tree isn't doing well. Since we moved it hasn't been happy.  Sure it's fruit never tasted like they should have, a little bit too sour, but it always looked and smelled great. Most of the clementines fell off and now we don't know what to do with them except throw them away since the chickens don't eat citrus. I don't want it to die yet, we've had the same tree for years and I doubt we will ever get another one.
