I've gotten a late start this year in getting my seeds started from crosses that I made last year. I've been germinating them first in the fridge, and then planting the seeds in pots outside. All are growing well so far, but I've still got more seeds to get planted as they germinate. I'm wondering if it would be safe to transplant them in the ground before winter, or would it be better to leave them in pots for the winter? They are growing in 4" tall pots, and I noticed a couple of roots poking out of the bottom of the pots already, after only a month. So far, the roots are only poking out of a couple of them that I checked, but I didn't check all of them. I was surprised to see roots that deep already. I have a cold frame that I can put them in, but I'd rather not do that if it's safe to plant them outside. I'm pretty sure I'd need to put them in gallon pots to overwinter them, but I'm not sure about that either. This is only my second year at starting daylily seeds, so any advice would be most appreciated! Most of the seedlings, if not all, should be dormants.
