Cocanut tree help
I have a coconut tree I keep in a pot I have had it for a year now. I have not exposed it to temps below 50, During the summer it is normally 70 - 90F. It has been getting 15 hours of light each day sense early June our summers are 16 hours of light. The new frond is turning yellow i have no idea why, We don't have lethal yellowing here to far north what could be the cause of this i love this tree i want it to be healthy please help. The old frond is irrelevant it has looked like crap for a long time now. The new one being slightly yellow and brown at the tips is a bit concerning.
