The Q&A Archives: What is wrong with my Emerald Green Arborvitae?

Question: I planted 6 of these E.G. Arborvitae last summer. I picked 1/2 doz. or so bagworms off. We had phenomenal rainfall all yr. The bottoms of the trees are brown, some black area too, almost tar like. What's happening to them? Insects, fungi, disease, over water? I hope to save them so, what should I do?
