Well, I'm finally ready to throw in the towel
and admit defeat. My clivia are getting pitched -- they aren't worth the hassle.
Started some from seed about 10 years ago. Have 3 planted in the same pot (think it's a 10"). Two have stayed relatively small and the third has always had about 5 or 6 leaves. Thing is I live in an apt so there is no "cold" room to put them -- and I'm not about to lower the overall temp in my apt just to accomodate them. They simply aren't worth it.
Ah well, the seeds were free so at least it didn't cost me anything.
