Coconut damage and treatment
Hi, new poster here. Look forward to good discussions. Have a coconut in Orlando. Planted it in 2015 and made it through unprotected 2 winters just fine. Got hit by the January 2018 freeze. (6 hours below freezing, 4 hours @ 28F).
Protection: C7 lights around trunk wrapped in burlap and bed sheets. Inside thermometer by trunk never got below 40F.
Symptoms: New spears starting pushing out just a few weeks after the freeze. In March, it started showing signs of complications or stress. New fronds are wilting and some necrosis appearing. Last 2 fronds wilting in almost a "U" shape.
Treatment: After seeing some necrosis or signed of fungus, I did a treatment of fungicide and hydrogen peroxide.
Fertilizer: Like most others in Central Florida, I get spring stress from lack of Mn and K. I did my normal treatment fertilizer, K, and Mn on 4/1 (I have a regular treatment 4x per year)
1-2 weeks after freeze (2/1):
Today (4/24) Emerging spears looking ok
Palm meristem seems fine. I tug once a week and no signs of spear pulling out. Whether it is cold damage or fertilizer, is this normal after a stress event?
Florida 2018 Wundermap Wallop
Took these Wundermap screenshots this morning around 6:45, not sure if it was the bottom of the cold spell but here it is.
I see some quite notable cold on here, even freezing temps throughout central Florida even on barrier islands.
Winter solstice 2017
I thought it worth noting that it's the winter solstice in the northern hemisphere today. I like to celebrate the fact that after this, the days get longer even though autumn has come to a close and cold winter has arrived. I'm sure my friends in the southern hemisphere are excited at the arrival of their summer today as well! The good news locally was that we actually got rain in my part of Southern California which was a welcome break after a very dry late autumn which correlated to all the fires. I haven't looked at weather maps to see if Ventura and Santa Barbara Counties were so lucky as to receive some rainfall, but I know it would be a helpful respite in fighting the fires. The locally bad news is the clearing winds from the system passing which turned into a Santa Ana (dry offshore winds. This will not help firefighters.
My garden doesn't seem to mind that it is now winter, it has just sloooowed doooooown a bit on the growth with the cooler night temps and shorter days. How is your garden doing this winter solstice?
Snow in the South
Well this is interesting... How Is everything fairing? We have light flurries right now and may get more, but temps are not suppose to go below 30 degrees F.
Hemiepiphytes for somewhat cold zones? (7b)
Looking for Hemiepiphytes for zone 7b. I was thinking of wightia speciosissima but I don't know any sources or their hardiness.
