Black spots on Thryallis shrub leaves
Hi We live in Central Florida and planted some Thryallis shrubs in early November. They're in unimproved sandy soil. They've been watered appropriately. Lately they've developed some black spots on the leaves. I'd love to get them healthy again, what should I do? Thank you, Carol T
