Q: We previously grew our orchids in a greenhouse in Chicago. We now grow them in a sunroom in Jacksonville, Florida. We are having problem with the plants staying too wet and developing fungal problems that often kill plants. We are having an especially severe problem with a cymbidium that, despite our continued spaying with a fungicide, still looks bad.

A: Your problem is not an uncommon one for people who move into an area with higher humidity than that to which they had become accustomed. First your mix is designed for drier areas, so it may not hold up well in Florida. The media may have broken down prematurely. All of these symptoms point to a need to repot your plants in a better-draining medium and remove all dead roots.
