Just a quick update on those Lithops that were stuck outdoors during the Polar Vortex. Days of cold rain are not good for Lithops. The ones that I hastily repotted and brought indoors did all right. But the ones that stayed out, well, I lost a couple.
Lithops don't let you know when they are in trouble. You find out a week later when the top gets a little soft, and slightly pale. Hmm....you might wonder what went wrong and what you can do, but by the time those little changes are apparent, it's a Dead Lithops Sitting. A few days later, this happens:
On the other hand, you can have a plant that looks like it's completely and utterly dead, yet it's feeling groovy. My Catasetum tenebrosum is now dormant. But as hinky as it looks now, it will rise like a phoenix in a few months, ready to bloom again!
