Question From: Bensalem, Pennsylvania, United States
Q: I just reported my zinna why are they leave turning brown, but still blooming
A: Sounds like a soil borne disease to me. A soil drench using a fungicide may work, but it is difficult to control fungal diseases once they become established. Actinovate is OMRI listed and safe for use around edibles, animals and soil dwellers. Best And Happy Yardening, Nancy
