Established Forsythia (3+yrs) are suddenly wilting and looking il
I am trying to figure out what is wrong with my forsythia shrubs and am not really sure where to look. My forsythia were transplanted to our new home three summers ago. They have been doing splendidly and have grown by leaps and bounds, some are upwards of ten feet or more now. However all of a sudden it seemed like over night one seemed to be wilted, a few days later the one next to it is wilted, and a third is beginning to wilt as well. It's progressing from the back corner of our property line up towards the front of our property line.
We haven't introduced anything new to the yard that could have infected them with something. I looked at the leaves and they don't seem to be chewed on by anything or the like and I don't see any insects.
Our summer hasn't been too hot, and we have had a decent amount of rain at pretty regular intervals.
I am desperate not to lose these as they are the only thing offering us privacy in our back yard from a less than savory property next to us.
Any help would be greatly appreciated! Thanks so much!
