I am in my fourth year of growing citrus in containers and I am having problems I have never experienced in the past. All plants are in a 5-1-1 mixture, get Foliage Pro one per week, and have been treated with neem oil, and hosed off on a regular basis.

This is the first two weeks it has been sunny and warm here so I would expect to see some leaf drop from climate change.

The attached picture is of new growth and blooms on a Moro blood orange. This plant is suffering from severe drop of mature leaves and branch die back.
