My daylilys some years will look rusty due to rain or humidity.
What can I use to spray them safely for myself and cats?
Do I start in March since they are already 8 inches green and growing fast?

How often to spray with a hand held half gallon sprayer?
does it discolor my lovely green foliage on my daylilys?

Next aphids..is it okay to use a table spoon of dish washing liquid in a half gallon sprayer of water?

Does that discolor the foliage or discolor the bud that is about to open?


thanks

Can you clarify what you mean by "look rusty"? Do they actually have daylily rust, or could it be leaf streak or something else?

For aphids (and daylily rust!) it is 1% hand dishwashing liquid so I think a tablespoon to a half-gallon is stronger than necessary.

i do not have a picture to show you how mine looked last year in biggest rainfall in years
during May and June here..
It looks orange on the leaves..and I tried the white cloth under leaves and not really sure.
will look at some pictures on line
is there a recommendation to prevent rust so I can start in April ahead of time
for preventing it..should it happen?

do not want a spray that might harm buds...
thought I would spray before May lst when they are all budding..
thoughts?

If you're in an area where rust is endemic you likely won't be able to totally prevent it, and it will likely involve repeated spraying with fungicide. Orange does sound like rust but there are other things that can look like daylily rust. There are some pictures here:
