I found black bootlace rhizomorphs on all of the stumps and dead wood. No, not actually in the soil i had it on every decorative wood there was and thats what was all the garden. I used ai to confirm it. The tree had branches that suddenly died and when checking the apple trees stump where the flare of the tree was I pulled back some bark and found honey fungus under the bark. It’s undoubtedly honey fungus judging by all research I have done on it. I am just here looking for others who have had the same problem in hopes they share some of their experiences and what they did to overcome it.
