Any way to get rid of Cedar-Hawthorn Rust?
I have a Hawthorn and some globe cedars in the same area. Every year this Hawthorn tree gets cedar rust disease; it is unsightly. I already hate this tree with its awful suckering habit and nasty thorns. The ONLY redeeming thing about this tree is the nice white blooms in the Spring. Is there a spray that can be used in the Spring or during the growing season? The cedars are really healthy and I don't see any evidence of spore thingies on them.
