Great photos as usual Alain. Of course I like ALL lithops, but among these show I really like the pattern and coloration on the L. aucampiae and the L. dorotheae. I find the L. aucampiaes not long lived with me. They look great for 5 or six years and then they suddenly dry up and disappear. Hope your spring is starting off smashingly !
I have some aucampiae with 7/8 heads. Is this tempting fate? We had a couple of warm spells before a return to cold.
When is the best time to repot.
The standard advice is to repot just before watering starts. I always seem to have too much to do in late Spring and repot throughout the Summer. I have found so long as the compost is dry there is no problem. I can also remove the old leaves at the same time.
