UCHS Jakes Chapter used to sell them to fundraise. Dont know if they still do or not. You might be able to call and find out. There is/was a Christmas Tree farm over off of Tazewell Pike. Never personally did any business with them.
They used to sell them in the lot beside Chick Fil A in Fountain City but that lot is now a shopping center. Dont knkw where they moved it to this year. Not much help. Sorry.
Brother if you haven't seen a place that sells trees yet you might want to start getting out of Union Co a little more .. Bahahahaha!!!!!!!! Walmart just down the road has a ton Ace hardware and probably Rural king
