I have collected asterias cultivars. Their shape is flat and they have white flecking.Hana have you noticed any big differences in degrafted and own root Astrophytum asterias?
It depends upon the type of stock but the scion of white flecking will be higher dencity than own-rooted asterias.
As the result, you can not see the true appearence the asterias.
It was told you should not cut the tap roots of Ariocarpus because regrowing of roots was hard. But I found it was not true. The regrowing roots of degrafted Ariocarpus is not hard.do you still not recommend trimming ariocarpus tap roots?
I did tap roots cutting test of Ariocarpus seedlings but the result was not so good. The growing speed became slower.
