I have grown a single plant in a 6" pot to a 7 plant one in a 12" pot over 15 years, potting up about every 3 years, ruthlessly removing any leaf that has even a tiny blemish from some mite or other. I withdraw water totally November and December, water lightly in January. Each plant throws up at least one stalk that produces spectacular blooms. I can't accomodate a larger pot and the form of the whole plant is so good that I am reluctant to divide. Should I root trim and repot before it gets too pot bound or wait? Last repotting was 2 years ago and my inclination is to do it before the plant looks like it is not happy. Also, if I repot can the roots be cut only at the bottom? I have seen a pot that would give a bit more room on the sides but is shallower than the traditional 12' clay pot in which it now resides.
Lori: I am going to go on instincts here, but I wouldn't root prune a clivia. I think you should divide it up. You've obviously got the culture down pat to be able to have it grow and bloom for you so happily. All I've read and experienced (I've grown clivias for about 15 years), is that they do not like to be disturbed root-wise, and to only repot when absolutely necessary. Root pruning is more disturbing than repotting. I, myself, have successfully divided my clivia several times. There are about 4 divisions of it around town - given to my friends. I know it is a nice form, but I'm worried about root pruning, and putting it in a more shallow pot. If you want advice on how to divide, I can talk you through that no problem. By the way, what color is your clivia?
Chester, if you are still reading this please see my new post! I repotted contrary to your advice and have spectacular results!
