i have a problem with a juniper which is on a downward spiral for months already. It started with browning tips which become hard and stay on the tree and now the branches start to brown backwards. I don’t find any scales or other bugs on the tree. The roots are not perfectly established but they are fine and don’t show any signs of fungus or anything. The first thing which comes in my mind is phomopsis but today i took a look at the foliage under the microscope and saw this on the dead branches:
As far as i know phomopsis forms black spots and no white spots. My question is now, is this a disease in any way or could it be something else like dried fungus spray which i sprayed a few days ago. I really have now clue what these small white balls are. You can not see them with your eyes, only under the microscope.
I hope anyone has an idea or elsei fear that the time of this tree will come to an end which would be very disappointing due to the fact that it is a beautiful small shohin starting refinement process.
Thank you for your help in advance
