The Q&A Archives: Roses with spots

Question: How can I stop the black spot and holes in the leaves of my rose bushes?

Answer: Black spot is one of the most common diseases of roses. Fungicides will help control it, but you'll need to practice good garden sanitation (prune and remove the most obviously infected canes), and try to keep water off the leaves. Fungicides need to be applied every 7-14 days during the growing season. Some choices include Funginex, Daconil, Captan, Bravo. You'll find others in the garden section of your local Home Depot. I'm afraid black spot is just one of the challenges you'll face when growing roses, but the reward is worth the effort. I don't think there's anything quite as lovely as a garden filled with roses!

Holes in the leaves can be caused by any number of insects so I'm at a loss to recommend a single product for your roses. Why not look in the rose care section for products you can use?

Best wishes with your roses.
