I just bought this from Amazon last week. The yellow is getting worse. Is there anything I should be doing for it? How long until I put it in orchid bark?

What kind of orchid is it? Did you separate the two pseudobulbs, or did they come individually like that? If the yellowing is moving toward the stem, you need to cut that leaf. But into the green tissue, not the yellow, or the infection will continue to progress to the entire plant. I would not move to bark until you have some more viable roots. Keep the sphagnum moss airy and fluffy but don’t let it dry out too much while you are trying to promote root growth.

Those look to be very small keikis that were separated from the mother plant too soon. If that is the case, you will need to manage moisture in the media so that the plants don’t dry out. But you’ll have to balance that with the dendrobium’s need to dry out, especially as it’s watering need will be decreasing during the cooler months. This is what I would do. Gently unpot and look at the root system. Hopefully the other one will have more. Cut away any rot. Use an orchid pot that is roughly the same size if you have one on hand. A clear pot will be helpful to monitor root development. Otherwise, wash the current pot and add ventilation holes if possible. Place the plants in the pot, gently filling the bottom 1/2 of the pot with orchid bark. Fill next 1/4 with half sphagnum and half bark. Fill the top 1/4 with sphagnum. Work the media around the roots as you go. Stake the plants so they don’t move and disturb new roots as they develop. Mist the sphagnum daily to keep it damp (not wet). Only water when the bark is dry. The clear pot will come in handy here. If the pot is opaque, use the chopstick method to check for moisture at the bottom half of the pot. Place in bright indirect light, similar to what you need to rebloom phals, not typical dendrobium light levels. The goal is to give enough light to allow the plants to make food but not enough to dry them out quickly. Once you see root development, maybe 2” into the pot, SLOWLY increase the light and transition to typical dendrobium culture. Watch is as you alter the growing conditions and respond accordingly. You might consider searching on YouTube for keiki care. I believe Miss Orchid Girl has some videos. Good luck!
