I do not have so much job for cactus in winter but I start degrafting several plants.
I will dry degrafted plants and will be in pot in September.
The following photos are Astrophytum myriostigma v nudum cv khoyo, kikkou which I degrafted and rooted last year.
Since morning has been cold, they have started to turn the color.
I am not sure too late or too early but several asterias were in flower yesterday.
