Should I braid my Malabar Chestnuts, or not?

[Daintree]

I have a bunch of Malabar Chestnut seedlings, and am wondering - if I braid three together, will the roots get too crowded together?  They will eventually wind up in a 25 gallon pot.  I am hoping they will bloom/fruit in my greenhouse. Most of my fruit trees are in that size of pot, but there is only one per pot.

Thanks!
