The Q&A Archives: Black spots and curly Duranta

Question: I got yellow Duranta and planted them on June and were very nice. About three weeks back start seeing black sponts on one shrub and gradually became diffuse to all shrubs. Also, about 50% of leaves become curly and smaller in size. In addition two of them became 70% dry with blackish stems and leaves, looks dying. How can I treat them? thanks.

Answer: Duranta repens is normally insect and disease free so I'm not sure what might be attacking your plant. They adapt to most soils and prefer to grow in morning sun but shaded from hot afternoon sunshine. I wonder if the leaves are showing some signs of stress from the summer sunshine? Or, perhaps the curling leaves are caused by insect feeding? Since these are fast growing shrubs it might be to your advantage to prune away the diseased parts of your plant, both to remove the disease and/or insects and to promote healthy new growth. It won't hurt your plant if you prune it back. Hope this solves the problem.
