How to Prevent Rust Disease in Kentucky Blue
Every late summer I battle Rust Disease here in SE Michigan. I need to nip it in the bud this year..."Before it Starts"! What can I do... and when. I see the granule fertilizer like granule stuff in the stores. I need 15.000 sq feet. The problem isn't lack of fertilizing. I fertilize 4 times a year, Easter, Memorial day, 4th, and then labor day here in Michigan. The sub I live in used to be a golf course I believe it started there. I've used the Bayer Spray stuff when I'm aware its started, but I'm doing it every couple weeks and its apparent I'm not getting it all and it starts again the following summer. Please, need some good suggestions.
