Since I've been documeting this kind of thing before here's a new report on the seedlings from 2010 and 2011. The conclusion so far is that it isn't a good idea to sow in summer. Depends on the summer, of course. I read about it but now I can tell from experience. The one year old seedlings are doing much better than those I sowed during the very hot April or in summer. That's why the next bunch will probably follow in January. But now to the report. :)
You can tell how C382 bromfieldii v. glaudinae (sown 29.10.2010) have grown since August. The largest are about to change their leaves for the 3rd time. The rest of them have just done it for the 2nd time, while the one on top of the photo is taking its time. Same pot, same conditions, different outcome. Lithops are funny like that.
Next to the C141 lesliei ssp. lesliei v. mariae (sown 23.10.2010), which are getting their 3rd pair of leaves.
Summer kids, C308 lesliei ssp. burchellii (sown 24.06.2011) are in some kind of a stasis right now but they've really grown since August.
C388 steineckeana (sown 28.01.2011) look very pretty. I don't think there will be much change in their appearance in the future except for the size. Curious plants they are.
Last but not least, lesliei 'Fred's Redhead' (sown 28.01.2011) again with a better picture. :)
PS: The seedlings from 2008 and 2009 are in the middle of changing their skin right now. I'll blog about them later.
