Hi! I have a quick question. I have an oncidium papilio/psychopsis (I don't have the exact name with me right now), and although it has a flower spike, each time a bud forms, it dries up, doesn't bloom, and continues on it's merry way to another bloom, which fails to flower. Does anyone have any advice as to the reason? The plant looks healthy and has nice looking roots, but something is wrong. Thanks so much!
