Question From: Zachary, Louisiana, United States
Q: leaves on my red salvia are turning black and falling off. the discoloration seems to start at the end of the leaf. do you know what can b wrong?
Black spots on leaves are usually caused by a fungal disease. Take a sample of the infected plant's leaves in a baggie to your local independent garden center for a more accurate Id and suggestions of what is available in your area for treatment. Best Nancy
