Nov 14, 2009 #1 SMAdams Location NW Chicago subburbs, Illinois I have a few dying arborvitae and was able to isolate Phytophthora (the photo) and Rhizoctonia from root samples, there's excess water that's really the problem. I just wanted to pass along the photo, enjoy. Attachments 202061-Phytophthora.webp 115.8 KB · Views: 115
