Cannas that look very Unhappy
We have just moved into a new home with a well established garden. However, the Cannas look miserable - small, brown leaves with quite a bit of an infection, I think. I have attached some pictures. We live in Kampala, Uganda. It's near the equator but at a slight altitude. So relatively cool, lots of rain, and great gardening all year round. Thanks in advance for your help
This appears to be a Rust Fungus.
