So they're daylily seedlings. What are they planted in, it looks like a mix of vermiculite and perlite? What is their light source, and what have you been fertilizing them with, if anything. Also how long since they germinated? I would say they don't usually die back in August indoors unless they have a problem, and they certainly don't look too good, unfortunately. Usually outdoor ones don't completely die back in August either unless it's been very hot and dry and they go into "summer dormancy". They can get kind of ratty looking after flowering though.
