I have 2 such cactus.
One, which I bought the first "Normal", and the second "Double", which is why I bought it :-))
In addition, he was with little buds!
But my first Gymnocalycium ragonesei also began to produce buds.
My observation of the flowering of cacti showed that the Gymnocalycium stem had no hairs.
And the others, almost all of my cacti, fluffy pedicels.
I don’t know if this is right, but I sometimes wash my Gymnocalycium ragonesei under a warm shower.
Since it is covered with dust.
And sometimes I just blow it away.
Why not just make them happy! :-))
I really like Gymnocalycium ragonesei, it has a very unusual (at least for me) and interesting color: brown with gray.
Really looking forward to the full disclosure of their buds!
