Walter Pall's main blog about bonsai and his work with trees from day to day. Lots of good pictures of good trees and lots of valuable information about bonsai.
Hello Walter, This year I have got some sort of molding happening on my hornbeam leaves, I gently rub it off but it seems to come back. I have never had this problem in previous years. Also I have my trees on a terrace now with lots of fresh air and sun. They are yamadori and this is their second year, do you think it would be a good idea to defoliate them and give fresh leaves a new chance?Have a great day. Thomas Urban
To late to defoliate. Spray with copper - avaialble in any garden center.
