Platanthera, and habenaria flasking tips

[Thyroyalgeek]

‘Ello . I think I might try flasking for the first time on two natives and one non-native orchid, platanthera ciliaris, platanthera blephariglottis, and habenaria radiata. I do know about basic flasking but have never done it before, and if these are particularly difficult orchids to germinate then please tell me, as I’d rather start with something easier first. I’m guessing the platanthera’s need stratification first? Not sure about the habenaria. Are there any more requirements needed before flasking? If so, what are they?
