Hello. I am a bit new to this as you know and this is the first year with maples. I have some Amur maples, one specimen one, a clump. and a forest. Some of the leaves on them are fringed in white as you can see in the pictures. Also some of the very small leaves are almost 50% white. Is this a problem or normal. They are in dappled morning sun, in good bonsai soil and watered regularly. Then I have one acer palmatum that seems to sit there in the same area same soil etc with wilting leaves with some of them finally just wilting badly and falling off. I have pots of the same species and a forest pot of the same species in the same section that are fine. Originally the tree was just fine and showed no signs of problems, but now we have what you see in the two pictures. I am tempted to chuck the one and move on, but would like to learn something so will wait. Thanks, Peter
