Point is, they usually have enough reserves to come good with no special care.

Can't quite tell from the photo, is that O. ampliatum (I think technically it may be Rossioglossum now)?

No idea I am afraid. It was a NOID from a buy-to-die garden centre.
Last summer it pulled itself out of the fine bark it was potted in, as the lead pBulb was leaning so much. So, I gave up and mounted it, and it gave me a very nice return of a very generous flowering which has lasted till now. That must have been 7 months the 4 flower spikes have lasted at least, if not 8. All from that one lead pBulb!
