I have been doing some reading and it seems that it is harder to treat a daylily for rust after you have already planted it. And I know it is good to soak them before you plant them.
If you see rust on a daylily can you dig it up and cut the foliage off and soak it? Seems like that is the only way to get rid of all of the spores. I do like the Bayer 3-n-1 though, it said it is for rust, so should you put it down first thing in spring for all the daylilies or just put it down if you see rust on one at a time. Seems like if you wait till it shows up then you risk it spreading.
Here is the bad news, I planted 125 daylilies in the fall and knew nothing about rust so now I an trying to fix this before they all rot or something. There are a few I planted that are very susceptible and my plans were to dig them up and isolate them in a pot. But if this can spread by critters and wind maybe I should just throw them into the trash. I just don't think they are worth the risk and most of the susceptible ones were cheap daylilies to begin with.
I read something about temperatures, we almost got down to 20° one night, how long does it have to be at or below 20° to kill the rust?
