In every culture sheet I have red writes that epiphytic orchids should be fertilized regularly with diluted fertilizer... I followed the tips and fertilized them regularly. But later, when my collection grew, I stopped adding fertilizer. I haven't noticed absolutely any change on my plants since that (that was around a year ago)... When you think... How are orchids fertilized in nature? There is no much minerals in bark... From where do they get the food? I know that they produce sugars and other products using photosynthesis, but they virtually have no access to other source of 'food' like minerals and elements... How is that possible? A lot of energy is needed to create so beautiful and large, long lasting flowers... Where do they get it?
Is is there any orchid that requires heavy feeding?
