Switching Fertilizer
Hello everyone. I was wondering if it is neccesary to switch from a high nitrogen fertilizer to a high phosphorus fertilizer before the orchid flowers. I read somewhere that high P is not necessary for flower production and that a reduction in nitrogen is needed for the plant to flower. Does this mean that I should fertilize my orchids with less frequency with 30-10-10 before flowering? Or should I switch to a high P fertilizer and continue the same frequency? Most of my orchids are grown in bark, a few are grown in moss, and my vandaceous orchids are grown in coconut fiber. Can I use the same fertilizer and fertilizer regime for all of them?
