Southern California temperatures and a lot of coarse sand/pumice in the (deep) mix should do it. The largest plants have several perennial corms in a rosary. Splitting them will produce smaller (immature) plants. If they are producing lots of offsets something is wrong, as flowering is being postponed forever. Large containers or planting in the ground will give the corms the ample root run they evidently like.
