Thanks for the info. I traded me this A ritteri a couple weeks ago. Here is some pics, its 2 cm in diameter wide.

How big should the plant get for it to flower?

got a big plant S. Opuntioides. I want to swap a cutting of it
for another rare cacti . Like puna clavarioides , aztekium, Geohintonia or sometime else interesting.

It was a rather disappointing germination rate this season so yesterday I had to sow some Lophophora seeds I have collected from my mother plant. Had to see something sprout this spring

Thanks for your replies. All of my lillputiana seeds have now germinated and two of the Cintia seeds. But I'm worried about the aztekium seeds. Nor one have sprouted. Instead it looks that all 70 some seeds have mold on them and cold the seeds be bad?

Ive been sowing some aztekium, cintia knizei and blossfeldia lillputiana. I have the heater on so the temperature in the pots are 25C all the time. Should i turn off the heat in the nigth time? would it be better for the germination?

Nicely done! They look very good! I did 3 grafts of ariocarpus 3 years ago. They grown fast but they became a bit etoliated in the winter season. I kept them in the windowsill inside year around. How did you treat them in the winter season to get them that well grown(temperature, watering )?

Thanks DaveW for your informative answer, I've tried to Google that website and didn't find anything really. Maybe I will order the seeds. And I will post the result here on the forum/ André

Yes indeed. I've planned to graft them all on pereskiopsis so would have seen erlier if it would be a ritteri.. If so it would be some expensive ritterii seeds. like 20 euro . can't wait for some seeds of that cacti

I have seriously been thinking of ordering these five seeds from Gerardo. but I now started to doubth that this is honest site.. after all that the valdesii is so newly discovered. Or what do you think?

Very nice grafts your got there Didnt do any grafts this season. I have to compensate on that for the next season

Thanks paulize.

I,ve read around a bit and realized that its different features among the L. Willimasii. The flower color on this specimen are light pink, the fruits are pink and its self fertile so thanks for your information you shared in this thread

Kind regards/ André

Nice to see another Scandinavian here on the forum I think you should repot it as the other guys say. But I think you should wait until April. Because the plant is going dormant now, and it's really no benefit to repot it in this time of the year. Good luck with the cacti

I've noticed that its a sensitive plant. I got 2 pads of opuntioides, some hatiora rosea and an another "rare" one and put them all in the same pot for rooting. But i took one opuntioides-pad and grafted it. After some months i did see that all the 3 species in the pot had got fungus. So h...
