Question From: Rio Vista, California, United States
Q: I noticed my rosemary blossoms AND the leaves turned grey about the same time. Went out to look at it and the stems and blossoms, everything is dead. Over half the tree is dead. Other half is green and very alive. Please, What could it b? Thank you for your time, T.
Sounds like the plant suffered from lack of water and powdery mildew. Cut off the dead stuff and stake samples of gray material to an independent garden center for exact diagnosis and control. Also, make sure the roots of the plants do not dry out. Best And Happy Yardening, Nancy
