Sylvain, I would gently take the plant out of the pot and shake off all the medium, to see what the roots/caudex look like. I hope you don't have a problem! Mine would be rotting, me sweat, too!
Mike! Great news, all the plants are growing. I am very nearsighted, when I'm wearing my 4X grocery store glasses, anyway, and I could see growth on all the little guys. I am NOT unhappy with the plants at all. They had a long strange trip to get here. I am reassuring them they'll never have to fly again, I hope I'm not lying!
