Tropical Buxus species only

I am having problems finding information regarding the majority of Buxus species,which are tropical.I do not wish to
go over techniques aimed at any of the European,Korean or Japanese species,although I fully realize some will apply.Please,if someone has tips about timing of re potting,fertilizing,etc.for the tropical species,I would,of course, be most appreciative.I am not interested in the indoor approach at all.Thanks.

Which do you have?

Well,Jim,I think that of the Mexican species listed on the wiki page,it is probably Buxus mexicana.I purchased it from a woman who runs a small roadside nursery a few miles outside Todos Santos. No labels,of course.Been in the plastic liner for years.An inch or more at the base with great Nebari.Looks very much like an ordinary Box.
