upstate ny pterostylis

They are coming along nicely Charles. What temperature are you growing them at?

 

[cnycharles]

whatever seems to happen during fall and early winter on a northern kitchen windowsill, which is very dependent on the outside temps. though, I placed a piece of white cardboard between the plants and the glass when I put up the spotlight, so it's likely in the high 50's -low 60'sF for the soil, though the flower spikes that are growing upwards towards the spotlight shield are warmer as the cfl gives off some heat

update actually it's pretty toasty underneath the light, with the cardboard shield in place (when the light is on)

the first dragon is about to start yawning, so i'll have to take some progress images

I'm moving my pots to the new supplemental light area I have built. I'm hoping that gets them to spike!

Sounds like what they would like. Based on the progress of your plants I'd wager they get a fair bit more warmth than mine which always bloom in late winter, peaking in early March. I think the key with these is to grow them cool with a strong diurnal temperature shift.

I took an update pic of the spikes on 12/29, and then again four days later...

spikes/buds on 12/29; note the left spike is much shorter than the middle one

taken yesterday (1/02); the left spike is now quite a bit longer and is taller
than the middle one! I had moved up the light a few inches (and forgot to move
it back down) to get a standing picture of the buds, and in the few days the
one spike grew up above the other one! I have an orchid society meeting this
sunday, and would love to have an open flower or two for people to check out
so i'm leaving the lights on overnight

Almost there Charles !!!! Jean

Great!!!!!! Remind me of Arisarum vulgare buds when they develope too!

 

[cnycharles]

starting to open

I think that I dried things out a little bit too much! The first flower has browned off, and the one that was next in line is developing a bit, but the third flower (from the largest pot) is flying past the first two and is starting to open. I gave them a solid drink of water a few days ago and they are taking off

all plants/pots progress

I was very concerned about keeping the soil too wet, since many of my former aussie terrestrials had rotted, though some of that problem may have been because of extreme heat on the pots on my windowsill. I had seen that the soil of these two pots was getting a bit dry, but didn't think that they would be that reactive to dry conditions.... live and learn! They don't really dry out all that quickly, and I don't think i'm watering more often than each 1.5 weeks, if not two weeks

I just wanted to add that one of my fellow orchid club members also received some pterostylis curta tubers from David Mellard, and he is growing them much cooler than I am. He told me sunday that he had them in four or five different pots and media, one with all perlite (so that he can dig them up and check out their progress). He (Krum) told me that he hasn't watered yet, and that for some the leaves are just starting to poke above the top of the media

congrats on this succes

Dat da way ya do it! :clap:

very nice

I know this is an old thread but as usual, what a wealth of info just when I need it! Who wants in on an Aussie terrestrial order from Germany?

(Sigh) last year I probably would’ve said yes
Nyeric will probably say yes

Out of interest, what do the Germans have for sale?

About a dozen species, another dozen hybrids. Long list of Thelymitra too.
