I do not know what to do either. My narcissus are also starting to come up. mine are planted on the west side of the house, with the cement foundation right behind them. I am sure that the little sun that does come up is making the area warmer than normal. But, I am still not sure what to do about it or if anything needs to be done. would hate to lose my plants in the next freeze. Could really use advise. Thank you.

I too will be tuned in for some expert advise...I purchased a bunch of bulbs on sale (75% off) and many of them, narcissus, hyacinths, tulips were all showing about an inch of growth in the bags....fortunately, we dont really have a true freeze, even when the temps drop below freezing, it's only for few hours in the early morning hours, and the sun comes back out (70+)

so I'm also at odds as far as what to do with them...I have just not had time to get them planted...but I guess I must forego the after christmas shopping tomorrow and plant, plant, plant....

Our temperatures here are between 30 and 60 degrees everyday unless it rains when it is then between 40 and 60. My tulips this year are up in less than 2 weeks. They were chilled in a refrigerator for over 3 months before planting and most had no growth at planting time. Al

It happens sometimes here in Texas, native land of roller-coaster weather.

I usually don't do a thing, but if really low temps are predicted, maybe below about 22 degrees, I'd cover them with leaves & then remove the leaves when the sun comes out & the temperature rises.

(Every autumn, after I stop at Starbucks for used coffee grounds, I drive through a nearby neighborhood where every house has mature trees & every homeowner rakes them up & bags them for the trash truck.

I take home all the bagged leaves I can stuff into the car, use some in the compost heap, use some for extra wintertime insulation/mulch, & keep a few bags on hand for emergencies.)

This happens frequently, in my yard. These plants are so hardy they usually get through the worst,unharmed. I cannot remember damage. Snow, which, apparently, is a thing of the past, here, would be an effective blanket. Even without it, they all seem fine.

Not to worry! This is absolutely normal here in the south. I have daffodils, hyacinths, muscari, etc. popping up all over my yard, even the late-bloomers, and have had this happen more years than not. I have known them to grow 12 inches tall and form buds by the first week of January (not this year, but, who knows?), and then sit there for weeks waiting for the weather to be just right to bloom. Depending on the weather, I have had daffodils blooming the last week of January, and continue blooming into April.
Daffodils are tough! Just get ready to enjoy the show.
