That's so sad, Jim! Our orange groves went to developers years ago, but the county has put traps in my lemon tree twice now. They never say why or what the results are. That lemon tree was old when I moved here 28 years ago, and I'm getting a lot of silver skinned lemons lately. I don't know if it's citrus silver mites or citrus greening, but it seems to be getting worse. No problem with the lime...yet.
