Just a quick message: after cancelling our community Tu Bishvat event, I did what I always do: invented a new one. In fact, that seems to be the only real tradition of Tu Bishvat, inventing new traditions!
You can read my guide to doing a Tu Bishvat seder at home (with alcohol-free alternatives).
(Also available in French)
Also, if you want to go deeper, the whole kabbalistic work 'Pri Etz Hadar' has recently been translated to English. It's the source for Tu Bishvat seders, and a delicious text.
I'm vaguely working on a new tree-related podcast/post, will share here as soon as it's half-ready.
Shabbat shalom / chag sameach / be free as a tree.
