can you over-fertilize a catasetum

[estación seca]

The Mormodes I've seen in habitat in Mexico (dormant) grew in the crowns of Brahea fan palms that grew in cracks of an enormous, almost bare, smooth and shiny rock face. Braheas don't have tight crowns, so the plants got some overhead sun. They also received a large amount of reflected light up from the rock. Some of the plants had old inflorescences, and a few had seed capsules. The plants had hundreds of pseudobulbs. I remember being surprised such large plants produced very few inflorescences.
