Daylilly flowers dying
I have several varieties of Daylillies throughout my yard. I live in the Metro Detroit area. In years past, the blooms last days/weeks. This year, I'm noticing that I get a bloom that looks awesome on that day, but then the next day it is withered. The following day, it dies and falls to the ground. Is this intense heat causing this? If yes, is there any solution? If it is not, do you have ideas on what is causing this? I have a well sprinkler system, and the gardens are watered at 6:30 am for 5 minutes daily. It is happening with my Stella D'Oro's, my single bloom daylillies, and my tall daylillies. My gardens in front are East facing and shade over by 2 pm, and my backyard gardens get full sun until 6:30 ish, then shade.
