Repotting time

No roots on that one, Lindsey, so I didn't take any pictures

Most are seedlings from 2005, L. lesliei and L. coleorum are older.

Hope my N. mammulosus has roots like that one day!!
My seedlings from last April-ish are still quite small...

I've found it to be quite vigorous, Maria. Happy with lots of sun and heat (plus water obviously) even when young.

I have various Lithops & one plant of Pleiospilos nellii, all have been fine in an unheated greenhouse for the last several winters. I do ventilate well, & they haven't been watered since September so should be completely dry. In that state, they all seem to tolerate a bit of frost, though I couldn't guarantee that for every Lithops species. Titanopsis (various) and odd other mesembs (Rabiea, Bijlia & Conphytum) are OK with these conditions.

Thanks for the info, Mike, I'd wondered about Bijlia but couldn't find a lot of information.

Titanopsis calcarea is extremely cold hardy but not very tolerant of winter water, mine are still trying to flower outside although I wouldn't exactly call it winter yet

Some of the western Lithops species are not so hardy, to the extent that Steven Brack describes the coastal L. optica and the almost coastal L. ruschiorum as not tolerating any frost at all even in his desert conditions. I don't have plants of those species that I'm prepared to lose, possibly I'll try some L. herrei next winter. You just never know how hardy they are until you've killed some!

So, Mike, you don't water your nelii at all until spring?

Hi Mike,

I'm a bit surprised to read you watered your conos for the last time in Spetember because they're wintergrowing plants.
In september they only had there second watering here in Belgium.
I gave my conos water the last time somewhere in december, and will probably do once more in february.
