Help!!! My Grammatophyllum is infected!!!
 

Hi

My most priced orchid Grammatophyllum is infected. The stalks have a black smelly liquid and the leaves are turning black. Please see attached Photos

I need urgent help on how to treat this and nurse it back to health

Thanks.

Welcome to the Orchid Board.

I don't know what that disease is. I would cut off each stem with infection. Cut 10cm below the infection. Sanitize the knife between each cut with 70% alcohol, 10% bleach or heating the knife. Try not to let infected pieces touch other plants.

Let us know what happens.

Thank you
 

Thank you very much,
