I had this beautiful dark purple orchid that died when I was on vacation this year. Luckily, it did leave me a stem that has a baby orchid on it which I learned is called a keiki. Since my whole orchid had fallen apart, I cut the stem off and put it in some water hoping it would make it and it did get bigger. But it's been at least three weeks now since I've done so and no roots have showed up yet! The stem is starting to get fuzzy and the leaves not as stiff!
What can I do?
