My vanda was doing well, or so I thought. It had eleven flowers from November till they dropped on Monday this week. It also appeared to be growing and over the summer had root growth.
It is potted, which I know is unusual but seems to be done more often in the UK. It had done well that way since I bought it in March last year. I water very sparingly by dribbling a little through the bark each day, as advised by someone on OB who grows them the same way.
When I came to move it after flowering I noticed a worrying yellow at the base of the lowest leaves. I'm not sure how long it had been like that. These lowest leaves also showed signs of wrinkling. Not sure if either the yellow or the wrinkling shows up in this pic I took yesterday.
Today when I came to look closer while watering one of the leaves fell off in my hand. Then I found that just gentle handling of others caused them to just fall away with no effort. It lost 8 of it's 16 leaves and I'm not sure about the lowest two remaining ones.
There are two major diffences recently. It has been in dim light since December because I had it in a position where I could see the blooms well, but was not ideal for giving it light. The other difference is that all through January I have not been keeping up with any orchid watering very well, and my records show an average of every 3 days with only a dribble of water rather than every day (it went longer a couple of times).
I kind of hope it is either the water or light because that is easy to correct, but I'm worried it's something else. The roots as far as I can see are fine there are some good fat healthy roots on the surface of the medium. There are also good healthy looking roots further down visible through the side.
