3 years ago I retract this request with apologies. It looks like ztree does have a ztree-mode-hook.
I just hadn't seen it while searching through ztree's code, but I guess it must inherit it from its parent mode.
I'd like to do my own processing (like turning off the display of trailing whitespace) on ztree-mode buffers after they are created.
It would be nice if there were some hooks which allowed me to do that.
