Where are you? That makes a difference on what you should do.

At first glance those plants look like some form of Cryptomeria.

They are an outside plant.

I'd say they look more like Lawson cypress, Chamaecyparis lawsoniana. These are commonly sold as tabletop Christmas trees. But they too are outdoor plants and will not survive for very long in a hot, dry and dark indoor setting. Lawson cypress are not adaptable to planting in all parts of the country so it is important to know your location to advise on these. If they do grow well in your vicinity, these can get to be large trees over time - 15-20' or more.

also ... in being forced to size ... in a small pot.. for the holiday ... usually the roots are a complete mess .... making it even more difficult to replant ...

one thing for sure.. in winter ... indoors ... do not water them like you might water .. water loving houseplants ... tend toward dry ...

as noted.. where are you ... it matters as to whether it will live outdoors ...

I'm in lower Michigan. Frozen ground and cold temps right now. So what do I do? Thanks so much!

Lawson cypress are likely borderline hardy in your area as are Cryptomerias (if that's what these turn out to be, but I am doubtful). Keep in the brightest, coolest location you can manage indoors but away from drafts and out of direct sunlight. Keep the soil just evenly moist, not wet. If it survives through winter indoors - no guarantees - go ahead and transition to outside gradually in spring and then you can plant them.

But because of your location, these little trees may not be long term survivors. Maybe Ken can address how common either Lawsons or Crypts are in MI and how well they might fair in the ground.

Ken - here is hopefully a better pix. Pots have no drainage holes - should I punch holes in these or put in bigger pots with drainage? Thanks!

i would take it to a good nursery ... a and see if you cant get an exact sized pot ... so you can slip it out of one.. and into another .... looks like it might be close to a gal pot.. which isnt a gal... but thats another story ...

its going to have a hard enough time indoors in winter.. with the watering and humidity ... that i really wouldnt want to be doing any significant root disturbance right now...

i still can ID it .. are the white things berries/cones????

at worse.. maybe drill some holes ....

We need a close up of the foliage. Your picture is blurry.

Lawson Cypress is way more common than Cryptomeria, especially for a Christmas tree.

Larger pots with drainage would be a good start and then follow the advice above.

Here's one more photo. The white dots are just loose glitter they dusted them with. The pots are no where near a gallon - more like 8 oz! Thanks

Nursery gallons (known as a trade gallon) are not a 'real' gallon - only hold about two thirds of a gallon and are most often just over 6" in diameter and about 6.5" deep. Your trees look to be in something close to that size but you can certainly pot then up to that size or slightly larger. Whatever you do, unless you make sure the pots have good drainage, your trees are not going to live long at all - other than water plants - anything grown in a container MUST have good drainage.
