My rose leaves suddenly look as if somebody has burned them on the bottom. What causes this, and is there anything I can do?
This is probably a spider mite problem. Mites suck the sap from leaves, causing the burned look. You can try washing them off with water twice a week. If this doesn't work, you may need to use a pesticide. Check with a local nursery.
