jimscott Posted July 26, 2009 Report Share Posted July 26, 2009 I've got numerous pots of Mexican pings thriving on my grow racks, even P. gypsicola. I also have several P. moctezumae crosses. Out of all these pings, the only one struggling, is the straight up P. moctezumae. Does anybody have a suggestion as to what they are requiring that is different than water, light, well-drained media, and a little less acidic soil than typical CP's?

jimfoxy Posted July 26, 2009 Report Share Posted July 26, 2009 I don't yet grow this species, Jim; I can only suggest you could try increasing pH a bit with suitable media. Quote Link to comment Share on other sites More sharing options...

C.Weinberger Posted July 26, 2009 Report Share Posted July 26, 2009 Hello! Well I have the same problem. This plant is the only one, that doesn´t want to grow. Cheers Chris Quote Link to comment Share on other sites More sharing options...
jimscott Posted July 26, 2009 Author Report Share Posted July 26, 2009 Hello!Well I have the same problem. This plant is the only one, that doesn´t want to grow. Cheers Chris Even scarier! Now if Joseph Clemens and/or Eric Partrat say they have problems with them, I will throw my hands up in defeat! Seriously, I will try repotting into something more alkaline. Does perlite change the pH any? Quote Link to comment Share on other sites More sharing options...
jimfoxy Posted July 27, 2009 Report Share Posted July 27, 2009 Does perlite change the pH any? No. Anything containing calcium carbonate will; crushed limestone, powdered raw chalk, crushed shells, crushed tufa? etc. You could even buy a suitable piece of tufa rock (if you have a tropical fish shop nearby) and stick one on that. Changing the pH is only a guess - it may not be the thing to do, but they do naturally grow on calcium carbonate based rock according to A World of Pinguicula website.

johnvdw Posted July 27, 2009 Report Share Posted July 27, 2009 I have not so much experience with P. moctezumae yet, but one very important condition I have noticed is that P. moctezumae does not tolerate high temperatures. Hot conditions can kill P. moctezumae quickly, while other Mexican Pinguicula species are seemingly not affected by these conditions.

jimfoxy Posted July 27, 2009 Report Share Posted July 27, 2009 (edited) Looking at the temperature data on the World of Ping website, this one does seem to grow at a cooler location to many. Edited July 27, 2009 by jimfoxy Quote Link to comment Share on other sites More sharing options...
jimscott Posted July 27, 2009 Author Report Share Posted July 27, 2009 Mine is just on a grow rack, so it is ~21-22 C. I just transplanted it to a mix of perlite / crushed coral / egg shells / sand / LFS (to plug the holes a bit). I either saved it or killed it!

jimscott Posted July 28, 2009 Author Report Share Posted July 28, 2009 Here's its new setup, along with cuttings that have been crowded out by parent plants: Quote Link to comment Share on other sites More sharing options...
osmosis Posted July 28, 2009 Report Share Posted July 28, 2009 (edited) Mine grew really well for years in highland nepenthes conditions, not more than 25oC daytime, 10-15oC night temperatures, high humidity I use an inorganic media, with added crushed limestone tufa Unfortunately I went through a rough patch with maintaining interest in my collection last winter and it dried out too much, which nearly killed it. It has fragmented into tiny plantlets and is currently growing back fast Edited July 28, 2009 by osmosis Quote Link to comment Share on other sites More sharing options...
jimscott Posted July 29, 2009 Author Report Share Posted July 29, 2009 Wooooooowwwww! Not sure I can get the day/night differential unless I put it outside, along with the D. regia. The rest is do-able. Quote Link to comment Share on other sites More sharing options...
osmosis Posted July 29, 2009 Report Share Posted July 29, 2009 I have a mature flowering regia and a number of young plants all doing well in the same conditions. If your regia is happy, maybe the moctezumae will be as well. I sold a few gypsicola x moctezumae recently and was suprised by how few roots there were even on a large plant. I think that a high humidity environment, together with a very open inorganic mix kept barely moist might well be what they like - maybe best considered as practically epiphytes Quote Link to comment Share on other sites More sharing options...
jimscott Posted July 30, 2009 Author Report Share Posted July 30, 2009 Do you think I should take it outside? Bad things seem to happen, in a variety of ways, when I take the Mexican pings outside. Yes, the D. regia is doing well outside, now with 5 dewy leaves. Here's a picture of the P. moctezumae, repotted, with all the dead leaves removed: Humble beginnings for now...

MarcelvW Posted July 30, 2009 Report Share Posted July 30, 2009 I hope yours will survive. Mine is doing fine, I am not growing it for a long time. I use small amount of vermiculite in the soilmix. Quote Link to comment Share on other sites More sharing options...

Hi Jim, I have a Moranensis x moctezumae cross that is blooming right now in a west window with bright, indirect Sun. In a water tray. Here's the flower, in bloom right now: Quote Link to comment Share on other sites More sharing options...
