rot ???
Hi everyone !
I am writing on behalf of a friend of mine. She grows her orchids in orchidarium. Lately, pretty many of her plants show signs of rot. She has lost about ten flowers during the last two weeks. Leaves are falling off very quickly. They are brown at the base and there is some yellow colour above the brown part. It doesn`t look like a "normal" root, when water stays at the crown, because the inside leaves, at the crown seems to be ok. First fall the leaves that are far from the middle. There are also some yellow stripes at the middle of the bottom side of the leaf. She didn`t change anything in the environment recently, like temeperature, humidity or watering schedule. She didin`t introduce new plants too. Can it be some kind of virus or other disease ? All comments are welcome thanks in advance greetings from Poland Martha |

samaki,
If you could tell us what kind of orchids she has, how often she waters them, what she fertilizes them with and how often, whether or not she mists them and if so at what time of day, and at what temperature she keeps them at night and day then maybe someone will respond to your question. She might also tell us what the rotted areas smell like if she chushes them in her fingers. I have some kind of fungus or rot (glomerella) that has a "sweet rotton" smell. It has killed around 90 orchids, all in the miltoniopsis family. Bob "samaki" wrote in message ... Hi everyone ! I am writing on behalf of a friend of mine. She grows her orchids in orchidarium.
