I'm new to Dendrobiums. I've been watering this little guy weekly with some superthrive and once every 1-2 weeks a weak fertilizer. I have some tiny leaves at the base of the plant, which I'm hopeful means more canes. I'm puzzled by what it's doing at the top of one of the canes. Is this a keiki? Will I need to cut it off and pot it at some point? Thanks to all you wonderful people willing to lend your expertise.
