Toni,
Within 1-2 weeks. You are aware that seeds should not be totally covered by the potting medium? Seeds should only be pushed in half way.

Dries, no wasn't aware seed should stick half way out of soil..is it too late to lift it?
In 82, I started seed from a Clivia, didn't know what the heck I was doing, used heavy soil, only artifial light, and to this day have a beautiful Clivia from those seeds..
So, what do u think I should do? Thanks, Toni

You can lift them and replant. They are hardy.
Follow the link below for a good photo of germinating seeds.

Thanks Dries..I have to register to read how first post was done..I'll get to it later..off to the doc.
Thanks very much..Toni

I didn't know what I was doing with the first clivia seeds I planted and had them a few inches below the soil. They did eventually sprout but it took several months. The next time the seeds were just pushed into the soil and they germinated within a couple weeks.
