Did you get this one when Orchid Inn travelled to EU or did they export to you??
Do you remember what type of mycorrhizae product your friend used? I’d like to try that if I can find another supplier.This species can be a bit of a pain. They are subjected to a very wet monsoon in the summer, but they grow on limestone cliffs so they are never sitting in water. The winters are dry, but cool enough to provide heavy dew. We like to give them good drainage and extra calcium in the mix in the form of crushed oyster shells.
Paph vietnamense may appreciate beneficial microbes. I know someone who used a mycorrhizal product and grew a huge clump of growths. Then he couldn't find the product again and the plant went backwards. Ours grow and flower well, but never keep the old growths for too long. I suspect they are dependent on their association with mycorrhizae in nature and we can't quite replicate that.
Sad story, similar to some of my own sad stories about Orchids that died, especially vietnamense, it can be a tough cookie to deal with, I have had a number of them too, with varying success, this one looked very nice Guldal, and I can see that you grow in Greenmix toomy success rate has improved a Lot since I began with this Media more than 25 years ago, I have a vietnamense now from Popow thas has survived 2 years now from seedling so I am hopeful that it will maybe Bloom eventually...PS: Guldal IT would still be nice if you send me a private message
It might have a lot to do with the climate also? Parvis in general occur in the area where they go through cold winter and cool to vaguely warm summers based on what I have read about their habitat info.I have a seedling a couple years old and a compot in seedling size orchiata, perlite, and charcoal. I’ve learned from the seedling that I need to keep it more wet than anything else I seem to have. I use K-Lite as well but they’re all doing quite well!
Ralph,In April around 12 years ago I bought a P. vietnamense on an orchid exhibition in the Palmengarten in Frankfurt Germany. The plant was, with several other species (mostly without label), that all were in bad condition (damaged leaves, no flowers or buds) on a bargain bin. As I saw the broad leaves I was convinced to know what it was. Costing only ten Euros, the plant was very cheap, so I took the risk. At home I planted it in a mixture of coarse pumice, charcoal and bark and placed it on the windowsill (southwest exposition northern hemisphere) next to my other plants. A new grow emerged three to four months later. Around two years later, the plant flowered for the first time. Since then, this plants flowers regularly around every two years (two years ago with three flowers, this year with one flower). I have transplanted it only twice in the meantime, always in the same mixture. Since then, this plant produced several capsules (mostly hybrid pollination).
I have sown these seeds on a coarse mixture of pumice and pine bark, that I first sterilized in zip log freezer bags (in the microwave), then infected with soil particles from other pots where orchids germinate, after some months of resting to let the fungus develop its mycelium. It usually does not work with all bags, but with my restricted space, I get enough seedlings. They can stay in the bag for around two to three years.
In my personal experience the species is not difficult at all. As I have experienced so often, the main problem in successful culture of Paphiopedilum is to eradicate pests like Tenuipalpus pacificus and Brevipalpus spp. These mites are present in so many professional cultures where they are held down so that they cause only minor damage. When such a plant comes into a new culture (especially where the air is drier), these pests explode and destroy. Because of that, every new plant in my culture is put into a sealed bag, poisoned and stays there for at least four months.
All the best,
Very true. In my enclosure it reaches around 68-70 F in the winter and around 82 F in summer, they seem to be doing wellIt might have a lot to do with the climate also? Parvis in general occur in the area where they go through cold winter and cool to vaguely warm summers based on what I have read about their habitat info.
Nothing beats good growing conditions.
Sorry, I don't know what it was. Some sort of a powdered formula. Thanks to the pot industry there are many of these preparations out there at hydroponics stores now. I plan to do a trial with a few of them when I find the time. Just be careful as the liquid ones usually create a very acidic solution. We buffer them with potassium hydroxide.Do you remember what type of mycorrhizae product your friend used? I’d like to try that if I can find another supplier.
