Tanqueray Posted October 20, 2019 Report Share Posted October 20, 2019 Hi all, I have seed arriving for P. Grandiflora “French Alps” and P. Longifolia ssp. Longifolia “Odessa, France”. three questions: 1. do they need stratification? 2. What media would be best? 3. what conditions should I germinate them in? this is my first experience with pings. Thanks Quote Link to comment Share on other sites More sharing options...
Argo88 Posted October 20, 2019 Report Share Posted October 20, 2019 Hi! They are temperates pinguiculas, they need cold stratification... you can sow now or in November/December outside... you can use peat and sand, pure sand, pure volcanic lava..

jeff 1 Posted October 22, 2019 Report Share Posted October 22, 2019 Bonjour all 2 we need stratification for grandiflora a acid substrate like just blond peat for longifolia a calcareous substrate you can sow them right away or leave them at the bottom of the fridge to sow them in the spring warning our seasons are reversed for the new zealand it would be better to sow them away, fairly humid substrate and out all year round Quote Link to comment Share on other sites More sharing options...
Tanqueray Posted October 23, 2019 Author Report Share Posted October 23, 2019 Thanks for that. I started them before you replied, putting both on a mix of 2:1:1 peat:sand:pumice. They are covered and at the bottom of the fridge, which my wife is not impressed about. What would you recommend as a better substrate for P. Longifolia next time?

jeff 1 Posted October 25, 2019 Report Share Posted October 25, 2019 (edited) Bonjour actually in your country it is the spring ( summer in december-february), also for me, leave these seedlings out, especially cover them to prevent threshing of the substrate by the rain. longifolia is not a acid specie but a calcareous like a lot of temperate , then use a calcareous substrate for them . my substrate for these calcareous species (including mexican and some others) -cat litter with sometimes akadama (bonzaï substrate) 50% -pouzzolane 12.5% -calcareous sand 12.5% -river sand 12.5% -vermiculite 12.5% jeff Edited October 25, 2019 by jeff 1 Quote Link to comment Share on other sites More sharing options...
