Pinguicula marciano

Hi everyone,
I have bought a very nice P. marciano few weeks ago. Put it first on some sphagnum and lava rock as shown on photos. The next day, the spagnum was dry and so the ping looked dehydrated too. I repotted on a mix of 2 sand: 1 peat moss (carefully washed the sand and the peat moss !!!). It seems OK, I check on the ping every morning, looked good yesterday. However, at my big horror surprise, the plant died... My question: is it too dry or too wet the substrate ? I do not mist the plant but put osmosed water drop by drop at its feet, not everyday. What do you think ?

Some of those leaves might take and start new plants if your conditions are corrected. Hopefully you get a couple new plants from one!

Looks too wet for my liking also the potting media isn't correct. I have never been able to get Mexi pings to thrive in sphagnum or just peat and sand. Mexi pings don’t grow in the same peat or sphagnum bogs that most other North American Carnivourous plants do. Most Mexi pings are found growing around limestone rock outcroppings.

There’s a couple soil mixes recommended here for Mexi pings.

P.x 'Marciano' =P. medusina x (moranensis x ehlersiae) it is a horticultural hybrid

I think that when you master the culture in pot you will be able to continue on this culture a little special;).

what are your percentage of peat and river sand?

Hi Jeff, I use less peat than sand, let's say 1- peat/ 2+ quartz sand. Can you give more details on these '' little special '' please ? would like to know more on this hybrid. Thank you.

As many have repeated I think that mix is a little dense and wet. I have opted for a very open mineral mix for all of my Latin American Pinguicula, some of the wetter growing species seem to grow a little slower but I don’t have any losses to rot, even when the plants are dormant and wet. My mix is 1 part each of Turface, Perlite, Pumice, Vermiculite, and Lava Rock but I’ve been used no Lava Rock recently as the Pumice seems to be enough. This mix only wicks so far up so all of my pots are roughly the same height (Standard 3.5inch pots). After I switched to this mix I stopped having any issues with rot on all of the drier growing species and dormant plants have no issues. This is for both my indoor and greenhouse grown plants and I let the mix slightly dry between watering in the summer and keep it bone dry all winter.

I found through my growing experience that in most cases for Mexican pings, keeping things on the dry side is better than wet side. I have a Pinguicula laueana that I left unwatered for weeks and the soil became bone dry for at least a week. Despite being treated like a cactus, it is still growing fine. So I found out that I should not be shy to let the soil dry out a little before watering again. (for the treating my ping like a cactus thing, do not call the police for plant abuse)

for P.x 'mariano' see here http://cpphotofinder.com/pinguicula-marciano-3783.html

for many hybrids and some Mexican pinguicula we can use a substrate based on peat and river sand in the proportions 30/70 like the US subtropics elsewhere, if not for the majority of Mexicans use rather a mineral substrate with a limestone or gypsum base.

do not hesitate, when you can, to take them outside from mid-May to mid-October in the shade, half shade morning sun, rather also sheltered from the rain to avoid the dilution of the mucilage, they will love to eat little gnats, little butterflies, etc.

for my part their dormancy instead of mid October to mid May, in a fairly bright frost-free place, with a very slightly damp or even completely dry substrate especially for filiforms

H2O great ping and orchids collection ;)
