Thank you very much for that information, sooby. ***** It is not that I am not eradicating leaves (I am, if visibly infected), nor that I don't want to eradicate rust from the garden (I would love to). But clearly a single application of fungicides is not going to do the job (if it did, I might consider it, at least with respect to carefully spraying cut back plants and fencing them off), and I am not going to subject myself, my dog, the wildlife, or the garden (which includes edibles) to constant fungicide exposure due to regular spraying. I am not convinced that spraying does anything more than merely suppress (for a time) the rust, anyway. I have received enough daylilies from nurseries who routinely and regularly spray, that subsequently and shortly thereafter broke out into frank rust, that I am convinced of that. (Again, our climate is not normally conducive to rust and I keep an eye on things, so I am satisfied that the source of the rust was from the nursery, not from my garden.) ***** As for your idea of recycling the potting soil into the bottom of new pots, I have to ask if there is any data to suggest that the rust might be able to infect plants through the root or crown tissue? ****** Many apologies for the run-on paragraph; my *ENTER* key seems to have just broken.
