Hello Everyone!
I just wanted to share some pictures of a Dendrobium keiki that just bloomed this morning. I bought the Den back in Oct. Shortly after it lost all it's flowers and I trimmed the spike, It sprouted three keikis. One of them went immediately into spiking. I have a question though, As you can see the bottom leaves are yellowing. I don't think I'm over watering but maybe I am. Does anyone have any advice on how often Dens should be watered and how to tell when water is needed?
