Stanhopea seedling questions - Orchid Board

Greenthumb.5 · #1 08-18-2013, 03:06 PM

I recieved two stanhopea seedlings recently as in two weeks ago. They are Stanhopea martiana X self and Stanhopea oculata 'Eye Doc' AM/AOS. I have questions regarding to their care and what I should do.

The Stanhopea martiana is growing a new lead and has three growths with three leaves on them. Any advice on the culture and care of this species as well as opinions are appreciated.

The Stanhopea oculata 'Eye Doc' AM/AOS X self is giving me a hard time for now. The plant has one new lead coming as the new lead that came with it rotted off, and it has one tiny flask backbulb and three bulbs with leaves on them. Any advice on the culture and care of this species as well as opinions are appreciated. And can you tell me what am I doing wrong.

I put some moss to keep in some humidity for these seedlings. And I am calling for help with these seedlings.

New growths rotting off is typically from too much moisture at the roots. You might want to let them dry out a bit more or put them in a basket.

Also, the pics with burnt leaf tips are probably from too much fertilizer or too much heat.

Okay, thanks for the information and on the Stanhopea oculata, I see a new lead replacing the old rotten growth. YAY!!!

Also can anyone tell me how you grow Stanhopea martiana and Stanhopea oculata? Of course besides the basket.

How many years from flowering should this be or how big the pseudobulbs should be before expecting any blooms?

If you can show your collection stanhopeas, it would be very appreciated.

I've never grown martiana, but I know oculata and its allies can be grown like a Phal, but with more light and more fertilizer. And I would guess 2-3 years until your oculata blooms. If you can get it to push out more new leads, that time will be closer to 2 years.

The pseudobulbs of S. oculata and S. martiana that are mature enough to flower are approximately 1-1.5 inches. My S. martiana is a bit slow growing so it may take longer to flower than S. oculata. I often grow my seedlings in New Zealand moss to keep the roots evenly moist. The seedlings seem to grow rather well in this moss. S. martiana seems to do better with shade similar to a Phal like Steve mentioned and enjoys more humidity too.

So how would I know when they are large enough to be in a basket. What kind of basket is recommended? Teak or plastic? Also what medium is needed when they are in a basket and how to pot them into a basket.

Sorry for so many questions.

Plastic lasts longer, especially with moist spag. Either one will work though. Also, they can go in a basket at any time, as long as you can keep it moist.
