Question From: R. Allen - Oak Island, North Carolina, United States
Q: My young Rosemary bushes have been taken over by a weblike disease that is killing them. I have washed them and used Neem oil but the disease won't go away
Your plants may have downy mildew that is fatal. Take samples to an independent garden center that grows and sells these plants. Do put them in a sealed plastic bag and do not open it. Too much water, fertilizing, and poor drainage are all issues for rosemary. They thrive on neglect. Best Nancy
