It took a long time, but I am starting to feel like I can grow Dendrobium lindleyi. It needs to get to have some size, a three pseudobulb division doesn't seem to be enough. And it needs a REAL dry winter rest. Not even a "sympathy splash" of water during the winter. The last water this one got was November.
Dendrobium lindleyi grows from India to Vietnam. It is warm to hot growing and needs a dry winter rest. As the flowers mature, the color deepens. The genus Dendrobium (Den) contains 1200 species from all parts of Asia and the Pacific. Some like a dry winter rest, all like to dry out between watering. Flowers are long lasting.
I plan to leave the plant in one piece and up-pot it back in rock. It has been in the same pot for five years and it needs more space. I will go up two inches since using rock as medium reduces the problems of over-potting. I will try to disturb the roots as little as possible when I do it.
