I have a "pandemic" of plant rust that affects not only my Hibiscus but Morning Glory's as well in one bed. I have cleaned and cleaned, even replace the top 4 inches of soil and sprayed all of the landscape timbers with bleach. I'm very careful of how I water the plants and spray with fungicide but it still infects my hibiscus. It started with Morning Glory a few years ago so I quit growing MG's in the bed and this year I tried the Hardy Hibiscus (H. moscheutos) and Sorrel Hibiscus (H. sabdariffa) and now they have rust.
I give up.
Can anyone suggest a good replacement with showy flowers and/or foliage that is NOT susceptible to rust?
