Last season we had many discussions about my Day lilies because they were lacking blooming, well, they are blooming
like crazy this season! Am I suppose to or it does not matter if I pull off the expired blooms daily?, I have been but
is it a unnecessary thing to do?

Whoops, here is a picture, always good to have one, just ran out and took it.

You can deadhead your daylilies it makes them look neater. I deadhead the spent blossoms on mine when I have extra time or am taking pictures as to me a photo is spoiled if dead blossoms are visible. Some folks deadhead their daylilies in the evening so the next day the garden will have only newly opened blooms.

I only deadhead mine for a photo, it does not harm the plant or keep them from blooming or anything. I just pull them off and toss them on the ground around the area. You can put them in the compost pile. If you don't remove them they just dry up and fall off, it's just a matter or preference or if you have time

If you don't remove them, does the plant not then continue put energy into the flower head to create a seed pod. I remove mine thinking I'm helping the plant put it's energy into more flowers or to make the plant itself stronger for next year.

Once the scape is done blooming entirely, I just cut it off.

Connie, yes they will put energy into making seeds if a pod forms, plus I do not want seeds from a pod falling into my garden and growing. Not unless I make the cross and plant the seeds so I know what is growing. I want my daylilies putting their energy into more flowers I have been planting more that rebloom, are bud builders or have a long bloom season also growth of the plant is important to me. I don't cut off the scapes but wait for them to dry when they are easy to pull without damaging the plant. I am a member of the AHS also of their email robin, these topics have been discussed there for interesting insights. Here is their website in case you haven't looked at it there is quite a lot of information for folks to read all about my favorite plant the daylily.

I find myself doing this quite a bit lately. I work into the wee hours at home and my mom's place. Quiet work but as I see the daylily blooms turn to mush I pinch them for a clean morning view. Prolific heavy bloomers get snipped to avoid knocking off buds attempting the "pinch". No noticeable difference in day to day blooms but, for example "Chicago Apache" which has tight vertical scapes that I enjoy. With the high bud count and tight quarters, a fading bloom will often weld itself to a fresh bud or two. It can ruin a bloom or three without "much tender loving care". I love the plant for it's habit more than the profuse blooms but I hate to see lost flowers. I'm a night owl and it's a minimal chore. My pet peeve, nothing more.
