I own a dwarf eureka lemon tree and I cannot for the life of me find or see what is making the flowers,buds and fruit just drop off. The only thing I ever see are ants crawling around but they don't seem to be doing any harm. There are no aphids or any other kind of problem happening but the one I described above. That all happened in the spring now it is fall and there are all kinds of blossoms on the tree even our lime tree but it is cool here in central fl. and whatever got to it in the spring has not happened so far because I have been watching like a hawk. Please tell me if this has happened to anybody else and if so, what on earth do I do about it or even try to see the little critters. What am I looking for?
