I wonder what is happening to the lime tree and now most of the lemons have green spots on them. The lime tree started with yellowing leaves last year. This year we have disfigured fruit. We sprayed winter oil, but to no avail. The stems look bare. Can anyone please help me to identify the problem? The trees are about 18 years old -perhaps even older. Please ignore the purple leaves on the lemon. They are green as usual. Thank you for your time.
