Because they're generally not well cared for, I don't usually like to get grocery store orchids. Recently, however, I purchased one after being won over by the tiny, adorable flowers and branching spike. Later that week, unhappy that the moss still seemed as wet as when I bought it, I cut the spike (mostly faded anyway) and repotted into bark. It had a couple OK roots, but not a great mass.
Since repotting, it's already dropped 3 leaves from the bottom. I was expecting some leaves to drop, but now two more are turning yellow, and one is not exactly on the bottom. What worries me the most is that I'm used to leaves turning yellow first at the tip and then moving closer to the stem. However, all of these leaves have first turned yellow at the stem. What causes this type of yellowing/dying, and is there anything to be done to stop it?
