Rust on Daylilies

I have over a hundred daylilies in the front and backyard and they started getting rust on them last year. I cut them down to the ground and sprayed neem oil on them and on the ground. Then they grew back and became beautiful but after a while the rust returned. I have cut them down many times and sprayed every time but the rust returns. How do I get rid of the rust?

Neem oil or an all-purpose fungicide should work, though you may need to reapply every 7-10 days. Here is more information: https://www.gardeningknowhow.com/plant-problems/disease/learn-about-plant-rust-disease-and-rust-treatment.htm ^[1]
