If you don't get them into soil with water and light, they're going to die. Period. Since your ground is frozen, put them in pots now. You live very far north, so maybe tulips bloom year after year for you. Here, and in many parts of the country, they rarely bloom a second year, although the leaves will continue to come up every year. I throw them away and buy new ones each year. You be the judge of what you do with yours.

O, mine bloom year after year...and multiply each year, which is why I had to divide them.

I have a cold, dark crawl space. Would that be a good place to put the ones that have not sprouted?

As donnabaskets explained, they either have to grow or they will die. Unlike seeds which may be kept for years in a dormant state, bulbs can be kept dormant only so long and will either grow, consuming their stored energy as yours are doing, or they will die by just drying up. Al

Get them planted now. You will lose them if you don't. They are green now because they are ready to grow.

As a follow up:
I potted up some bulbs that won't tolerate my soil, and they're in my garage (cold, but not entirely dark). One is peeking its head out, and I've been ignoring it, though I do give them a bit of water every week and a half or so. Now it's getting more insistent, and is probably 2 inches above the soil (sorry, NO idea what it is). Shall I bring him inside and let him do his thing? Move him to the back porch? There are other bulbs in the same pot that have not yet woken up...

Thanks!

lilgreenfrog he will not go back to sleep. If you can, remove him from the pot and repot in his own space, in the light. With light he will turn green and grow in his natural shape. Al

Al, Thank you! I think he only has one friend, so he should be extractable. I'm assuming I should keep him outside in the light? I'm worried about the dirt freezing, so I could bring the pot inside if that would be better. I could also ferry it between the garage and back porch; it's a small bulb in a small pot.
Thank you again!

Lara

Not knowing what the plant is I think I would keep it on the back porch for now. Al

Will do; thanks!
