Transplant or leave seedlings for later?
I grew trumpet lilies from seed this year. I basically have two 4" square x 5" deep pots that I spaced 9 seeds in each. They all germinated and have a few wide blade leaves per seedling. I was thinking I would transplant them into individual pots but just read one source that said I should leave a potted seedling in place for a year before any attempt to transplant it. Will this be a problem with that many seedlings in one pot until next spring? Do I leave the pots outdoors on a covered patio over the winter as is or do I need to set these pots into something to protect them from potentially low temps in range of 0-10 degrees should that happen?
