I've noticed some black spots on my Zygopetalum today... I don't know what it is...
The plant is: Zygopetalum (Pinaroo x Titanic). It's placed on a south-west window.
I spray my orchids every morning to simulate the dew, I water them according a schedule... everything is fine with the bloom but the leafs....
Hope is not something bad I thought it may be the gentic thing...with the hybrid in the sun?... any idea?
