Thank you so much for your help everyone! So ok I won't worry too much as the flower spike is tall and gives quite a few flowers, thought I had a picture but I can not find it.....I do tend to cut the stem down at the base once all the flowers have ropped off however I get told I should leave it to see if it grows new flowers or indeed a keiki is that right? On a website it also says if you cut it below the first knot it encourages more flowering but I am not sure if they mean the first from the base or from the top....
With regards to the roots groing out are we all in agreement it should be repotted based on this? I thoughts many air roots were a sign of a healthy plant.
BigBill I have started to use Biopon Orchid fertiliser now with all my orchids. It is now very warm in the UK with temps reaching 30 degrees celcius (86 F) so watering twice weekly and keeping the windows open.
My other concern is with the Oncidiums i have. When I posted pictures of both I was told they looked very dry and need watering however since I have been watering more one of the bulbs rather than growing fatter turned its leaf yellow and it dropped off and looks like it is dying. Given they are in a plastic pot I cas see the roots and I have a feeling that the orchid may not be getting enough water due to root rot as some roots look yellow and damp. The medium is coarse but does not usually dry fast due to the high humidity level in my flat......so although I am wateirng more I do not ever get the feeling that the media is ever completely dry. What should I do?
