Dendrobium Leaves

[Alan Sailer]

I am am pretty new to orchids but have been happy with my successes. A half dozen phalaenopsis have been doing well for me over the past three years.

I have a single dendrobium which has bloomed twice since I bought it. After the last bloom another stem started growing. It reached about six inches with about six leaves, all a healthy green.

Two weeks ago the plant started blooming again. From an older stem. What I don't understand is that all the leaves on the new stem have yellowed and fallen off. What's that all about?

The plant is indoors, LED lighting and is soaked once a week, the same as my phalaeniopsis plants.

Thanks for any reply's.

Cheers.
