Health of a tree with selection of pot has always been my focus. Especially since I don't show.
I don't have time to watch this entire thing.
But what she says to the point I have stopped watching. I agree with to a degree.
That said...end of the day the pot falls on preference of the owner. So trust what you also like. If you aren't showing than truly is even less of a concern.
Masculine tree/pot...Feminine tree/pot has always been a good direction. That said...end of the day. Just enjoy your pairing. I can guarantee your tastes will mature and grow as your eye develops. What I once was drawn to. Has changed significantly.
I also prefer not to toss a tree into a pot because it's a trend. As you clearly state blue pots are seen for said species. I myself would buck that system...because I am not a follower. My Ginkgo clearly ...boldly stands on that. As I told Victor when he made my pot he had full reign other than my only stipulation was...no blue. As it's over done and I find it less appealing.
I know...yawn...it's been shared. Also...Scott Lee said to never put this in any pot less than 3.inches deep for health of the tree. So this pot is 3 inches in depth.
