Hi, It seems like at the moment I don't have much luck with some of my young maples. Both are in pots 1/ The Osakazuki seems to be subject to Powedered Mildew. It looks like people try one of the following treatments (or are they just preventive?): - hydrogen peroxide 3% - baking soda + water - diluted neem oil - copper sulfate - fungus fighter plus (for instance) Has anyone used any of these and got good success in getting rid of the mildew? Or is there any better option? 2/ The Oridino Nishiki that I got from a nursery not long ago and I think had the issue when I bought it (I should have checked more carefully). On the cut they made on the leading branch, there's a black zone, and on the branch a bit below that there's some darker zone. Do you think it is verticilium? Thank you for your help.
