I am assuming the advice that your daylilies will not rebloom is based on the fact that in your area you would just not get much if any rebloom anyhow. The fact that the deer ate the original buds I don't think would have any effect on the rebloom. I just want to mention that in case someone further south that would normally get rebloom might think that because the first buds and scapes were eaten the plant would not generate a second rebloom crop of scapes, buds and blooms. Actually, I wonder if the deer or anything eating the first "flush" of buds would actually allow the plant to have a better chance at rebloom (I don't know), just the thought crossed my mind.
