Mary: I really wish someone who enjoys experimenting would take the time to test the "baggy" theory on a rose or a daylily. I can't for the life of me figure out how blotching could occur in a closed daylily bloom without any entrance for "something" (Thrips, morning dew, rain, etc.) to come in. I can't see it being a disease of any sort since many of the initially blotchy blooms are replaced by clean/cleaner blooms in subsequent cycles; it just seems logical to me that there is an outside influence at work.......I hope you DO try the baggy experiment and let us know...........Maryl
