I recently noticed that one of my succulent houseplants, a kalanchoe, has powdery mildew on the leaves. I just moved and it is in a new location, but nothing else has changed. How to I treat the leaves? They now have brown spots where I have wiped it off. Thank you for your suggestions.

I've never treated succulents for powdery mildew, but have other plants using a fungicide purchased at the garden centre. Check your local extension website, or talk to the staff at the nursery to see what they suggest.
Powdery mildew is a disease that affects a wide range of plants, including agronomic crops, fruit, vegetable, and herbaceous and woody ornamentals. It is caused by many different species of fungi. The disease is easy to diagnose as its symptoms are quite distinctive. All powdery mildew fungi require living plant tissue to grow.
