I'll let him grow by putting him in a bigger pot with the head vertical
at this size he will put branches at the base

also forbesii for me

planting a plant of this size and weight without attaching and tutoring is stupid and criminal

this one has rose flowers

It is not because you cross 2 species of Lithops that you make hybrids systematically
Lithops are little subject to hybridization between them

and do these beautiful specimens produce seeds ?

if you have a method you do as usual but 90 ° alcohol is what I use when I make cuttings even with large subjects over 20 cm in diameter like Neobuxbaumia polylopha

another thing when you make the cutting some pure 90 ° alcohol on the 2 cuttings

it's the same thing the difference will be made in terms of rooting that will be longer to be done
I will cut and after 15 days lying to be sure that it is well cicatrized I will put the cutting standing on an empty pot and I will wait to see the roots to repot

thank for the flowers of this uncommon specy
