orchid dendrobium leaves have black or brown spots. Help

[orchid-lover]

Hi Everybody,

I need help on my dendrobium.
The leaves have some black or brown spots. Some spots are bumpy. See the attached pictures. Don't know what is wrong. Anybody know what is the problem ? How I can fix it. ?

Thank you

My take - right or wrong - is that the spots are what’s left of a past pseudomonas infection, due to water droplets being left on the plant that became incubators. It is spread easily by water droplets.

If you got the plant that way, it may not spread, but I recommend a Physan spray of the plant and the growing area.

I agree. Make sure you have a fan to help dry off your dendrobiums after you water too.
