I have noticed a large number of maple and other deciduous tree leaves with huge black spot on them this fall. Does anyone know if this is due to the wet weather we've had or is there some sort of infestation going on? Is it really Black Spot or is it some other nasty that we've not seen before? I am doing my best to keep any leaf fall out of my perennials but it seems to be everywhere and I wonder what we are in for next season!
