American Wisteria leaves have yellow/brown spots & coppery sheen
I have a potted American Wisteria...about 4 months old. It's growing really well. But I notice that a number of leaves have an almost gold/coppery sheen to them...and bits of yellow/brown spots. Some of the leaves then turn outright yellow.
Overall the bulk of the leaves look very healthy and green but I am concerned that these other leaves are showing the start of some kind of disease or something?
I do periodically spray the plant with Soap Shield and Pyola, just as a preventative measure....
