Need help finding resources pls

[u/ObjectEquivalent1155]

I’m trying my hand at growing some northern catalpa from seed. They are all about 6 months old currently. I’ve gone from cell trays , to 1 gallons, to 3gal/5 gals currently. Looking back I didn’t address the flare when they were repotted into the pots they are currently in. Now i’m looking at them develop ,and i’m a little worried i’m girdling some of them ! I tried finding resources on how the root flare develops but I can’t find much. Can a tree wizard muster his beautiful words into the comment section please 🙏

Yes I know they’re packed in tight, they’ll be moved soon lol

Clip those roots running round the side, they'll choke em out. There is demand in ETX for these trees. They are great for growing beside ponds. Hook yourself up with someone who digs ponds if you can! Also post your trees in local Facebook gardening groups, many people are hunting for native trees.

Photo of the mother tree, Planted in 1972. Northern Catalpa are beautiful! It’s sad they aren’t used much where i’m at. Im trying to change that 😎
