Potted Valencia orange tree dropping leaves
I have a beautiful potted Valencia orange tree that has recently been dropping healthy green leaves at a alarming rate. It has one orange the size of a softball on it. It does have a mealy bug problem. It is not over watered. Could it be the mealys? I have it in full sun in my green house at the temp of 71 degrees. All the leaves are shiney and bright green. I pulled it up from the pot and the roots are healthy. This is my 1st orange tree and have a Meyers lemon so worried in case the lemon starts to do the same. Also any advice how to get rid of mealy bugs?Thank you for your advice!
