>>2183912I'm definitely going to replant them before they can get a second year of growth on, but I figure it might be a good idea to let the first year of growth finish, so they can be a bit more hardy before I try to transplant. They did only start sprouting at the beginning of July.
>you may need to bring the plants inside during the winterOh, I'm not terribly concerned about them surviving the winter. I got these seeds from plants growing out in the woods near me, so I suspect they're well suited to the winters we have in central NC. Reason I have them in pots is because I live in an apartment, so I can't exactly plant a hedge of these things, as much as I might like to.
>Definitely make sure to get deep pots when you transplant the seedlingsI have to wonder: How deep is deep? Sure A. triloba is probably going to put out a 30 foot taproot or something crazy, but it's a 30 foot tree. The A. parviflora plants I've seen in the wild (that I got the seeds from) weren't much higher than a few feet, so I can't imagine it would be 4 feet of plant above ground and 30 below. I suppose it's also worth considering that I probably won't be putting these in the ground any time soon, so I'm hoping they'll do well enough in a pot due to their small size.
Pic of seedlings from a few days ago, for reference. That's maybe 2 inches between the dirt and the rim of the pot.
