Hi, we are located in southern california and I am having a bear of a time keeping our boxwood shrubs happy. The leaves lool like they have white spots all over them and almost like a spray paint spatter mottling of white and green.
I took a picture of the bottoms of some of the worst leaves and they have what look like a strip of tiny white dots all along the stem (attached)
I have treated multiple times with neem oil, horticultural oil, insecticidal soap and haven't made much headway.
Any help would be greatly appreciated.
