Hello, everyone. How are you?
I had a quick question.
My son brought home a Shortleaf Pine Tree from School today. And I was wondering, can those trees be kept small, and be like an indoor tree, or kept outside by the door? Also inside a big enough pot, not in the ground? Because we live in apartments right now. I'd hate for it to die. And I think it'll be good to help teach him how to take care of plants/trees. Please let me know as soon as you can if anyone knows. Thank you so much! Take care! I hope I've explained my question good for you. :)

Also, if you could tell me some ways to do it? Like how big of a pot would be good, which type of soil, etc?

It can be done but it is a labor of love with zero guarantee for success.

Your little pine will be happy in a pot for at least a few years. It will not survive indoors - outside by the door will work. Pines need well draining sandy soil. Don't overwater.
