Thanks for the feedback.
I had a dracula (chestertonii) but burnt it as it is just too hot where i live.
My Madevallia was in a pot with sphagnum and one day all the leaves just fell off - still green
.
Curiously I have a pleurothallis on another cone - for almost a year now. It flowered beautifully and just recently, I noticed that it seems "dry" - the leaves - which occasionally fall off it you touch them. I DID move it to a less light spot in my living room, so maybe that was the problem (just switched it back now).
I am doing something wrong with my minis (methinks caring too much about them...) but will study and learn more..
My encyclia pseudobulbs seem to be fattening up a bit, there are new shoots coming out, so all seems well for the moment. I will post a pic once there is something healthy to show.
Cheers
Doug
