Guy 27 Report post Posted February 25, 2019 According to the care info provided by Triffid nurseries, crushed Tufa rock is ideal for Mexican Pinguicula. Oddly, they don't sell it! Easily available from ebay etc. What's the view from Pinguicula experts here? Tufa, or other substrates? Thanks. Guy Quote Share this post Link to post Share on other sites
Ali Baba 20 Report post Posted March 18, 2019 I grow a couple of mexican pings, both in the mix that Adrian Slack describes in his first book, they seem to grow very well in this. I tried laueana in an inorganic mix but it didn't really like it. Once potted into Slack's mix it went bananas and now I have a thriving potful.
