Answer: I think what you are seeing is winter damage. Few pests bother Ixora. If scales and aphids are allowed to build up, black sooty mold will appear on the leaves. Insecticidal soaps can take care of both of these concerns. Occasional nematode damage is reported, and generous use of organic mulches will also reduce the injury from these microscopic soil pests. You can prune to remove the damage and healthy new growth will appear. Best wishes with your garden!
