Q.Pitaya Tips Are Redish-brown Colour, Is It Health?
My Pitaya (yellow Dragonfruit) plant is one year old. Some parts of the plant have redish-brown tips but some are green. There is a new stem growing from the plant and its also the redish-brown colour. I am worried since it’s my first seed grown plant. Is this normal? What can I do about it? (I want to eat fruits from this plant, will it also be affected bcs of the tips?)
