Does anyone know if Dragon Fruit(Hylocereus Undatus) or Pitaya always needs to be pollinated to set fruit? It seems that some varieties do and some are self pollinated. I dont even know if mine is red or white let alone what named variety it is. I planted it recently outdoors. Should it be in shade? I have heard shade and sun... I live on the So. California coast. It stays mild in winter and summer. Thanks for sharing your advice.
