When I see leaves growing, and that might be only two weeks for a Celadine or 6 weeks for a Scott Pratt, I will gently tug upward on the stem. If there is resistance to dislodgement, there is rooting. If the stem just comes easily out of the perlite, nothings going on. Of course, since I am nosey, I always will remove that stem just to be absolutely sure. I want to be sure the stem is still firm and there is no sign of rot. It is easy enough to just slip the stem back into the perlite if there are no roots.
