Dont know about indoors- you would have trouble containing it, but outdoor in New Zealand we usually plant then under trees and then leave them to their own devices. Thet are vigorous plants and are not fussy about location, although I should add, we dont get frosts here.

Indoors, Clivia do well in bright light. In a cool room (about 60 degrees), my plants live throughout the winter, with just 2 widely spaced waterings. I keep mine under fluorescent lighting for 16 hrs per day. In spring, after frost has past, the go outdoors (in shade) for the summer. They bloom annually for me, usually in early-mid spring. An 8-12 inch pot is sufficient for them. A good prescribed dose of a soluble fertilizer, every 2 weeks, helps during the summer.

They are said to bloom better with a spell of cooler (frost-free) temperatures in fall, though I have not confirmed this. Being pot-bound also promotes flowering.

Indoors, they don't require direct sun but a little morning sun would be good. Let them rest nearly dry for several months between about November and the beginning of March, then resume regular waterings.

Guess our climate must suit them as they grow lik eweeds here. used in low maintainace public plantings everywhere.
Not unlike agapanthas.

I grow mine indoors, in a huge container, part shade, under a ficus-tree. Don't fertilize at all, and water every 4 or 5 days, no dry-period, and no artificial light...

It still blooms every year - guess I have a "green thumb"?

Mine grow in the backyard in a fairly shady location. We had snow this year on Christmas-first time ever-and I was really worried about them but they came through fine, getting ready to bloom now. Don't know about growing them up north though. Freezing temps are really rare for us. Good luck! Tally HO!
