I have 2 small plants on own roots. They are slow but not difficult.

Now that the brouhaha concerning my pictures of Aztekium valdezii (discovered 2011) has died down perhaps Mr Hldyard could explain when the policy changed to allow pictures of Mammillaria bertholdii(discovered 2013) to be shown and commented on in the Forum. After all he locked the post in September 2016 because he said any plants from Mexico after 1997 had been illegally purchased.

I could tell you, but I’d probably be either banned or deleted. Sad to say...
