my epiphyllum flower from early summer, and still flowering now. it barely grow any leaves this year. I think it's not good for my epiphyllum in the long run. I had thought about to give it high nitrogen fertilizer. but it should be in dormant soon. I am not sure it's good time to fertilize it still. if I do. I can only fertilize it once. is there any other way to stop it to form flower buds?
