Yellowing pseudobulbs on bulbophyllum phalaenopsis

[JCarcache]

I just recently bought my first bulbophyllum phalaenopsis. After a few days I noticed the pseudobulbs started to yellow and shrivel. The orchid is mounted on fern bark ( this is the first orchid I’ve ever mounted so I’m not sure if the mount is suitable) I mist it every day and the temperature is 70-80 F. Please help!!

Unless you are misting very heavily, water is probably not sufficient. It pretty much has to grow mounted, but the surrounding sphagnum should be pretty wet, and it could probably use more - Bulbos in general hate to dry out.

Roberta is right above. Bulbos are extremely thirsty orchids. Most need to stay almost sopping wet, especially this one. The roots should not dry completely or the plant is set back. All the photos of healthy and/or blooming Bulbo. phalaenopsis I've seen show them growing in baskets of sphagnum moss, never mounted unless in a very high-humidity wet greenhouse.

Your plant is severely dessicated. Dunk it in a bowl of water now for several hours. Once a day dunk it in water for an hour. I would move it to a basket or pot. Get a container large enough to hold the mount, preferably a wood basket with open slats. Put a layer of long-fiber sphagnum moss on the bottom. Set the mount in that. Pack sphagnum around the mount so the moss layer conceals the old mount. Water it once a day, and keep it as humid as you can.

Do some reading on Bulbos, and this plant.

Congrats on the new plant.

I agree that it needs more water. I drench my bulbo every day (Oh no, I just remembered to do it today when I typed this) and it has stayed green for a few weeks now.

Also, regarding the species, this bulbo can get really big and ot has very stinky flowers so you better prepare!
