30 Foot Acer Tree
I've just noticed several inches of whiteness on a lower branch which still has leaves further along. I've never noticed this before & wonder if it could be a fungus & if so, how can I be sure & how can I treat it? This was once a pink/green/white leaf variegated tree but now has all green leaves having exhausted the original acid soil we planted for it; there are sycomores & birches in the area where we live but the soil is quite heavy with clay deeper down. The tree is about 15 years old.
