Question: I have a problem with fungus growing on my squash. How do i get rid of it?

Answer: Squash plants can develop a disease called powdery mildew. It is a fungal disease that attacks plants when environmental conditions are right (warm days, cool nights, some humidity) and air circulation is poor. You can help avoid powdery mildew by giving plants the required exposure to sunshine, and plenty of elbow room so there's good air circulation all around them. Remove the affected leaves and stems to keep the disease from spreading, or you can try to stop the spread of the disease with a fungicide such as Soap Shield. Best wishes with your squash.
