I'm new here, so I don't quite know where to put this question.
Anyway, I planted daffodil bulbs (a double variety, don't recall which one) sometime in mid-November. I walked around the garden beds today and noticed that some of the tips have pushed up through the soil. Not very much, thank goodness. The bed already is mulched. Should I be concerned? Should I cover the tips with more mulch? Any info is appreciated.

Well, it did get cold early, then it has warmed up again quite a bit, right?

But, yes I would definitely cover those early tips with some more mulch, if only to protect them from critters walking on them. (but also to keep them from drying out if there's not much snow cover coming . . . who knows??) Leaves, or pine needles, or anything that comes to hand will do.

I agree, toss a bit more mulch over them and then don't worry. Daffs are extremely hardy and they "know" how to match their growth to the temps. The worst (absolute worst) that can happen is they come up, get frost nipped or frozen and you have no flowers. It won't kill them.

Many of my Daffodils are right at the surface of the mulch, ready to go. I see this every winter and it has never been an issue. And a great thing about Daffs is they're not attractive to rodents or deer, so the green tips in winter aren't a temptation. They're really tough and hardy, you should see a lovely display in spring
