Article: African violets are susceptible to a number of different diseases, including mildew, blight, and stem rot. Always wash your hands, put on gloves, and clean your gardening tools before and after handling any organic matter to prevent the spread of diseases from other plants or household objects. If you have a diseased plant in your home that hasn’t improved with chemical treatment, throw the plant away and inspect the rest of the plants for signs of infection. Since the crown of the plant is so close to the soil, dead leaves and flowers can cause too much moisture near the stem, causing it to rot. If you see a dead or dying leaf, trim it immediately and remove it from the pot to keep the plant healthy. If many of your leaves seem to be curling at the same time, try moving the plant to a warmer location. Sometimes, cold temperatures can cause the leaves to constrict and curl. Mealybugs and aphids like to crawl around on the fuzzy leaves of African violets. If you see the bugs on the leaves, physically remove them by forcefully spraying them with water to knock them off the leaves.  If the problem persists, spray the leaves thoroughly and replant the violet into dry, sterilized soil. Many insects will hide on the underside of the leaves, so be sure to spray both the top and bottom of each leaf. You can also use an insecticidal soap for pest prevention.

What is a summary?
Garden with clean hands and tools to prevent diseases. Remove dead blooms and leaves immediately to prevent stem rot. Spray the leaves with water once per week to remove visible insects.
