blue23rose,
I watched a video form Oaks daylilies yesterday and he said they used a weedeater on their plants when they started looking so ratty, and there too their foliage came out in a couple of weeks looking pretty and green. Someone else on here stated they loved the way their foliage made such pretty clumps after being trimmed back and put out nice new fresh green foliage. I also have heard of people just mowing the foliage down, but my mower does not go high enough with the height adjustment for me to feel comfortable doing that. Plus my plants are not positioned so I would not be crushing some while trying to mow others. Right now I have a lot of rebloom scapes still that should bloom, so I don't really like the idea of non selective trimming of the entire plants.
I spend a lot of money on chemicals to control rust, leafstreak, leafminer, etc. to keep the foliage looking nice and green, but none of the chemicals I buy help one bit with summer dormancy caused by heat stress. I have moved summer dormancy right up their with rust on my list of daylily faults .
