How do I get rid of powdery mildew on my goji berry tree?

Question

I would like to use an organic fungicide if possible. The top of every leaf is covered, and once new shoots come through, they get covered too. It’s a young plant. I planted it out this spring. Getting a lot of flowers but no fruit. I believe this is because of the powdery mildew. I would be grateful for any suggestions/information.

Powdery mildew is a common problem, but fortunately also treatable. This article will point you in the right direction: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
All plants have their own defense mechanisms, so your number one goal as a gardener is to provide what your plants need to be as strong as possible, so that they can ward off things like powdery mildew.
