Evidently we have a very fungus-y yard. I have 2 tall elderberry bushes in front of house. One on left always had severe fungus, I cut it back to the ground 2 yrs ago and threw all in trash. One next to it looks a lot better with some fungus. After cutting back I sprayed stump and remaining bush heavily with "natural" fungicide several times. Remaining bush also had aphids being "farmed"by ants! The spray worked for the aphids but not the fungus. The left hand diseased bush came back surprisingly tall but always with curled leaves and a lot of powdery mildew too - so maybe at least 2 kinds of fungus.

Suggestions? I now have copper-based spray I was thinking of using next week, also thinking of cutting bad bush back again or maybe even digging up.

You can spray fungicide all you want but it won't fix the problem because the spores lie dormant waiting for the right conditions and Boom its back. The main reason you have this problem is you have drainage issues and the soil is staying wet too long. As long as you have this issue you will have mold problems. Add compost and other organic matter to help with drainage. If you had your pH checked at the soil lab, you would find its probably very alkaline and needs to be lower with amendments.

Work with the soil and forget about the plants if you want to stop the mold problems because mold problems start with the soil. .
NOT A EXPERT! Just a grow worm! I never met a plant I didn’t love.✌
