New and old coconut palm...
Here's a pic of my coconut palms:
One on left is my newest coconut palm, and the one on the right is the one I had the longest. All the fronds you see on it are California grown:)
Which one do you think looks happiest? I wonder what causes the difference in color between the two? I know my oldest coco has not seen anything below 36f, but does stay outside most of the year here. Low humidity and hot temps above 105f is probably why. I do use a palm fertilzer so it should have everything it needs.
I bought the new one to plant outside in ground with no root heating cables to test my area again. Last time failed, but I think that was do to the record breaking cold this winter. It was still green with very little damage when temps dropped to 28f, which usually is the coldest it gets here and does so maybe 1 to 3 times at most a year. What killed it was three days in a row and their lows were-25f,23f,and 26f.
Anyway good luck with all your palms:)
