I live in central florida and have had a triple robellini for approx. 5 years now. Around the middle area of the trunk on two of the three, the bark (if you will) seems to be peeling off. I do not see any bugs. Is this something normal perhaps? Also can you tell me what the bundles of small grape looking things are. It seems like it has more than usual. My tree has had scale I believe and I spray it with a mixture of volk oil and something else that escapes my mind at this moment. Thank you.
