well, except for the iris, I would just cover them up with some leaves or mulch for the winter. I don't rake my leaves up till spring for just that reason. but then I don't have a lawn only flower bulbs everywhere. your flowers should be fine, under some cover. snow won't hurt them, they like the cold. it's frost you have to worry about. that's not good for the bulbs. they could probably use a little more dirt on top of them, too. perhaps they aren't buried quite far enough. not the iris of course, they like being above ground & uncovered. by spring you should see some very pretty flowers come up.

Thanks so much for the reply, aggiegrad. =)

I had planted the tulips at the bottom of the bed I dug, which was about 7 - 8" down. The hyacinth and scilla were planted at ~6", and the iris between 4 & 6" depending on what the instructions for the varietal were - except for a few of them which were larger and the instructions were to have the rhizome just peeping out of the surface.

I mulched everything under 3" of mulch when it got a little colder out. But it seems it just has not gotten cold enough here for the ground to freeze, though there have been frosts.

Normally at this time of year the nights should be in the teens and 20's Fahrenheit. The days should be in the 30's or lower most days. But we're seeing temps between 6 and 10 degrees warmer in the day, and only the last week or so have the nights gotten down to below freezing. This is the problem, I think. I picked a great year to try my first bulb bed. =)

It's a relief to know they should be OK though. We do still have some leaves in the yard, usually we do a first pass in late fall and then clear the rest in spring after thaw - there are a lot of old trees around us. I'll gather a bunch and cover the bed with them.

Thank you again! Happy Holidays! =)

Hi there,
I did the same as you at my place on the cape. I planted after Thanksgiving and was actually worried it was getting too late to plant. Now my crocuses decided to bloom and all the others except the daffies are putting shoots up. I wonder if the crocuses will re-bloom in February/March when they're supposed to.
