I have always understood that clivias prefer to be pot-bound. My four-crown clivia has been in an 8-inch pot for several years and its roots are beginning to spill out of the container. The plant itself seems healthy and blooms at the right time. But I'm concerned about all those roots coming up at the surface. What is the official position on this? Just how "pot-bound" should a pot-bound clivia be?
