Well, my Kurume Hino Crimson Azalea didn't take very well the two weeks of low temperatures and low dry humidity *just after being repotted*. Too early.
So instead of a ZipBag as suggested by @leatherback (couldn't find one at this big size), wrapping bubble plastic will do.
Or at least I hope so; it has been possible in the past to bring bonsai almost hopelessly dry back to life.
Time will tell.
