This happened to ours YEARS after they were planted. They started getting small brown spots. I thought they were little bugs at first. We treated them and everything. Had the Ace Hardware come out and help where I bought them. Nothing helped. They were brown and DEAD MEAT in two weeks. They were both about 40 feet tall and around 15 feet wide. I'm lookin at Spartan Junipers now, but trees are expensive.
