Charley, you are so funny! Seriously, though. The one failing to mulch every year must be planning on weeding or spraying herbicide. In fall, I experimented with Clethodim to kill quack grass that had all but extinguished my Elizabeth Salter, among other things. (A certain grower that sells clumps sometimes has quack grass hiding in those clumps! They say not to separate fans but now I wish I had. A few years later, quackgrass infestation!) Anyhow, the daylily seemed to be fine and the quackgrass was at least discouraged. I'll test it again before widespread use. Anybody else used Clethodim for grass in DLs?
And I have moved my infiltrated daylilies away from the area, separating them down to single fans before reclustering and replanting in a fresh spot. Bermuda grass is also horrible. I like deep edging to keep it out of beds. Learning the hard way!
And violets! Ugh. You snooze, you... 2-4D? And Preen! When those little seeds- from the pods above ground and the subterranean asexual pods- are stratified by winter and then germinate.. OMG! I snoozed. I'm still weeding.
