How To Save Cold Damaged Coconut Palm
Question: Hi Susan. I have a big 12 years-old Coconut Palm. After hard winter the palm became brown and drooped down to the ground. I cut them off. But now the brown dying look is progressing to the top. I don’t know what to do. Should I water a lot with epsons salt? My neighbor across the street has 2 palm trees and one is almost all brown. Any quick suggestions? Thank you for your help.
Answer: Coconut Palm Trees can’t tolerate temperatures below 20F. I would even say 25F is too cold for them. They are warmth loving palms that grow best in zone 10-11. Even mature palms have hard time tolerating low temperatures. At this point, there is not much you can do. There is no quick way of fixing it. Keep watering your palm. Don’t cut the leaves unless they are completely dry or if you see that they are rotting.
The most important part of the palm is its bud. If the bud was damaged by cold, your palm will most likely die. If bud was not damaged, it should recover, but it might take over 6 months. Fertilizing will not help. It could put even more stress on your palm. Cold damage palms have weaker immune system and could get fungus infection. To prevent that from happening spray the palm with Copper Fungicide. ~Susan Brian
