No the daylily leaves, called fans, are useless without the root. Just ignore the cut leaves or pick them up if they bother you. I had thought you ment some were yanked out of the ground. If they are all inground and just had the leaves cut off they will just grow new leaves and be fine.

Stella really is tough!I have it around my mailbox.They repaved my road and the paving machine burnt Stella to a crisp,but up through the wreckage came tons of scapes!What a Gal! Betsy

if the roots are still there, they will be back. but, after all this time, that might be doubtful. my parents moved into my uncle's home years ago. every spring, after they bloomed, my dad would mow down my aunt's peonies. they would come back bigger & better the next year. of course he always waited till after bloom. if he had did it before, I'm sure there would have been quite an argument between my parents. since peonies were always one of mom's favorites. which reminds me, I should go past the house one of these days to see if they are still there. that house has been sold 3 times since then. in a week or 2 go take a good look at the ground where you think the peony is, & see if you see any shoots coming up. as long as the root is there, they will be back. good luck.

This is good to know...for most of the time we've lived in our house my husband has mowed our lawn himself, but in recent months with an upcoming move and his Saturdays needed elsewhere he's had to hire a young man to do it on a weekly basis. After the first or second week I noticed that the one native azalea to survive of 3 I'd planted along the west-facing side of our house had been mowed down to a stump. It was just 12-18" or so in height but it still should have been distinguishable as a wanted shrub and not a weed. The following week it was mowed even lower, and at my insistence my husband has put a wooden stake next to it. For good measure I've added a sign pointing out that this is (or was) an azalea, or what's left of it. As I said we are moving soon so I have less of an investment in its fate, but I did pay for it and it might well have added some appeal to the yard's appearance.
