Thanks for you help and patience with this!
Photos attached - one of the whole plant, and one of the yellow stem (that's bent in half since this morning). The liquid is oozing from the stem just below the yellow bit at the 'joint' where you can see the new shoot has come from.
There is one main stem on this orchid, with five stems branching off that, 2 of which have gone yellow, and a third which I think is just starting to go at the tip.
There are a further 2 stems off the main one that have dried up - but as this has happened regularly since I've had it, I'm assuming that's normal. I tend to leave these stems until they fall off on their own.
The main stem and leaves all seem fine, other than having lost some fleshyness as I mentioned earlier. In fact, having looked at the plant carefully, the whole thing seems to have lost fleshyness - all the stems and leaves seem to be a little wrinkled and not quite as firm to the touch as they were.
FYI, there are 2 things that might be the cause or at least be part of the problem (not that I know much!!) 1) this orchid has always been planted in soil for as long as I've had it (7 yrs), but as it seemed to be doing OK in the soil, I've left well alone. 2) it's on a window sill that gets afternoon sun, and as it's suddenly warmed up in the UK over the last couple of weeks, the window has been left open all day and night. Could it be the sun and/or the draft??
Many, many thanks.
