I have a large lilac hedge surrounding our property on the north and east sides. Likely planted in the 1970’s and about 10 feet tall. Last summer and again last week the leaves suddenly turned brown snd dry. They bloomed nicely this last spring. Last summer was hot snd dry. This summer rainy and cool. One garden center said blight another said stress. Any ideas?
