Thank you for the replies, Weng and Kenni.
As both spikes developed at the same time and grew at the same speed, but
only one died, it is hard for me to work out what went wrong - so many
possible reasons, it seems. However, I had been rotating the plant
regularly to maximise light all round, so perhaps the one that died was
towards the window glass during a period when the temperature dropped or
rose too rapidly. If the plant produces spikes next season, I think I
shall
move it towards the centre of the conservatory where the temperature is
probably less likely to fluctuate so much.
Thanks again
Kate
