The Q&A Archives: Disease on Lantana

Question: I see black spots on the leaves of my Lantana shrubs. Do you have any idea what it might be, and a possible remedy?

Answer: I can't tell from your description but the spots could be a fungal or bacterial disease or evidence of lace bug damage. They feed on the leaves and excrete little black droplets which could look like a disease. If it is a fungal or bacterial disease you can simply prune the plant back to remove the affect foliage and stop the spread of the disease. Or, if the damage is from lace bugs, just hose the plant off, making sure to rinse the undersides and the top sides of the leaves. That should take care of the insects and their droppings. Good luck with your lantana!
