Hi,
I'm a new member. I've had orchids for about 2 years with some luck but not much. Mostly I have trouble with root rot apparently from overwatering. My orchids are in a huge sunny southwest facing window. Now that its winter and the heat has been on I've put a humidifier in the room. The rh is approx. 50%. Anyway, when I buy an orchid, usually a phal or paph or oncidium, I buy it when it's just about to bloom - I have it while it's in bloom and it's healthy and then once it's done blooming, I repot it in a tight clay pot with the proper orchid bark. I usually fertilize every other week and water thoroughly once per week. It seems like I'm following all the proper directions but I'm constantly having trouble with root rot. Right now I have several Phals that I repotted about 2 months ago - applied fungicide - and now their leaves are dark green, limp and wrinkly and they are not growing. This happens way too much. What am I doing wrong?
