I have a job that I've had for about 8 years where the Blue Stars have looked fine during that duration. They get full sun from midday on, grow in O.K. clay-silt soil, and are treated three times each spring and early summer for prevention of tip blight, which I know they're notorious for. They get hort oil spray every winter to help prevent mites. I heard that junipers usually like it dry, but we're having a real big drought here this year in S. Ohio, so I've seen to it that they've gotten a couple of real deep root soaking waterings about six weeks apart. And finally, I've done the famous notebook paper test, and haven't seen spider mites, yet they all seem to just be in a general state of decline since the spring. Any ideas? What if anything do you guys feed them in the fall?
