Type of fertilizer (N-P-K) for young black orchid, select which many containing N elements to stimulate vegetative growth such as Dekastar 22-8-4, Gandasil_D 20-15-15 or Vitabloom 30-10-10 and type of fertilizer for orchids grown, to stimulate flowering such as Hyponex (blue) 10-40-15, Gandasil B 6 - 20 - 30 or Growmore (orange) 6-30-30.
