Maryl, I respect your solution to the Salvia issue!
I always say, when I no longer feel like manually fighting the leaf rollers on Cannas, I'll have somebody who wants to do that dig them up and take the away. Putting chemicals on them could be harmful to the hummingbirds who love them so much, not to mention the anoles and little frogs who like to live in their shady greenery. I don't do any chems either, and if a plant just can't do well without that kind of intervention, out it goes. Sometimes natural predators will move in and balance things out, but if not, out it goes.
Like a rose that gets black spot. There are plenty that don't. No need to bother with the fussy hybrid teas.
Some plants I keep as host plants on purpose though, like passion vines. Gulf fritillary caterpillars are welcome to eat every bit, like they usually do every year about this time. Asclepias for monarchs.
