I have a friend in Kent, SE England, who grows hundreds of daylilies to sell. She has had terrible problems with gall midge and keeps Outrageous as a trap plant. This year she is going to cut off all scapes except one from each plant which she will 'bag' in the hope of breaking the cycle. My garden is small (though I have squeezed in over 150 daylilies in my mixed borders) so I would rather keep plants that are not affected.
I will get rid of Outrageous, Edge of Darkness and Cosmic Hummingbird which have never bloomed properly unless they surprise me. I potted them last year to see if it would help (and I mulched the pots with stone chippings) so fingers crossed. I have put in mid-late season varieties instead.
