Good winter morning...hope you are warm and cozy...my 10 yr old Clivia has bloomed once...we had to stick it outside for the summer while we gutted and remodeled our house...and basically forgot about it. Finally brought it back in during Fall and it bloomed beautifully the next year, but not since. Suppose I should repeat that next year!
The solution is simple: you need to gut and remodel your house annually.
