   Encephalartos ferox

   20f, completely defoliated both of these with ease. I have seen burn on ferox begin at 28f and any frost or ice will burn them. These plants took 16f last year unprotected and didnt die. However one only had one abnormal flush that looked like it was close to death. Both have basketball size caudices.

   I check this forum often looking for species data but sometimes I feel that the information people share here is of little practical value because we only share the minimum temperature a species has seen but how about next day's maximum? Knowing only the minimum doesn't help much to know the real hardiness of a palm. Some of you live in climates where it may get, say, 26F at night but then will reach a balmy 60 next afternoon. Whereas others will see 26F at night and then just 35F or even 32F next day. We all know that these two hypothetical situations would affect the same tree in totally different ways. So how about everyone shares not just the minimum their palms have …

   Southeast Baltimore County Lowest Annual Temperatures (Past 20 Years)

   So being the palm dweeb that I am, last night I was researching the lowest annual temperatures for Baltimore (my hometown) and I realized that the lowest temperatures were recorded at BWI airport. The airport is cooler than my location and I was curious what the same temperatures were in areas closer to me. So on the days where the lowest temperatures were recorded, I searched the temperatures at the weather stations closest to me and these were my findings for the past 20 years: 2019: 8° 2018: 5° 2017: 12° 2016: 12° 2015: 4° 2014: 6° 2013: 15° 2012: 15° 2011: 15° 2010: 16° 2009: 10° 2008: 16° 2007: 12° 2006: 16° 2005: 13° 2004: 8° 2…

   Vallejo, CA, (USDA Zone 9b/Sunset Zone 17) Advective freeze last night, with frost. Dew point hovered just below actual temperatures during the coldest hours. Humidity was considerably high for an event like this in Northern California. Generally during similar cold events humidity levels out in my area are consistently quite low. ~70% damage on horizontally exposed leaves. This is a juvenile 5 multiple clump planted last July 4th, 2020 so a pretty dense set of leaves packed into a small area, which coincidentally results in some leaves being exposed and damaged, and others protected and damage free. This clump is under wide open sky near a west facing wooden fence, less …

   Texas Freeze Damage Question

   Last winter after Hurricane Harvey we had a bad freeze in Galveston. It damaged my Bismarkia and Queen palm. The Bismarkia is fine now but the Queen palm isn't. It put out two fronds out about half way and then more new fronds are a foot long or less. The two larger fronds are turning brown at the tips and no getting any longer. I think everything is stuck. Is the such a thing as "crown crowding" or something and what can I do?

    This is not the method I suggest for toasted coconut! Potted Hawaiian coconut palm exposed to sudden temperature of 26 F for several hours at the end of October 2019. It is now in the ICU recovering and according to the doctors will need extensive rehabilitation. Please don't torture your coconuts like this.

    Northern California freeze damage data

    Floridians have theirs, South Cal have theirs (aka Palmpedia), time for those of us who live in North California (or in similar climates across the globe, like the northern Mediterranean coast) to make a freeze damage record. I guess most of this region belongs to the zones 9a to 10a with rainy winters. It would be useful to see how different species react to the freezes we get. So, if you have had frosts/freezes in your garden, please let us know how your plants have fared. Palms or not. Later I will combine everything in a spreadsheet. Please write temperatures, species of plants and observed damage. Personally, I cannot contribute anything yet as our winter h…

    Well - here’s my précious Triangle palm -I rescued her 2 years ago - she survived last year’s 14 freeze temps here in St Augustine while tucked against the east side of the house during a construction project. She is now placed in a lovely but lonely location in the open on the south end of the house near the pool. Our last frost day was 2 weekends ago. Fronds have evolved to this deep bronze over the past week. I applied copper fungicide to the spear area but that’s it. Any suggestions?

    Areca ipot dead at 36 degrees

    I wanted to let other palm owners know how very cold sensitive Areca ipots are. They were doing well and healthy until the temp fell. Wow do they hate cold weather. Them and Areca macrocalx didn't just get burned they died out right. Most of my other 107 species of palms did well. I'm experimenting with palm species that will grow in my new coastal location in central Florida. I'm about a half mile from the beach on a barrier island. My area just of south of Daytona is listed as zone 9B. Yet I see other plants that make me think the island that I'm on as opposed to the mainland must be 10 a. As a barometer, I have been aggressively trying to grow as many species…

    Freeze Damage - What to do?

    My wife and I just bought a new house in New Orleans with two palm trees in the front yard. This is the first time I have ever owned palm trees. Unfortunately, one of the two palms started to lose a considerable amount of bark from around its trunk. I did some research and the only thing I was able to find as to why this may be happening was freezing weather which would damage the palm and create oppurtunities for fungal and bacterial growth. I'm not sure if this is the case, but we had temperatures drop to as low as 20 degrees fahrenheit recently and a considerable amount of wind. I sprayed each palm tree with "Bonide Liquid Copper Fungicide". What'…

    Hello. I live in East Tennessee and about 4 years ago I planted a couple of Windmill Palms out in my pool area. This past Christmas we had a string of 3 or 4 days where it was very cold (around zero). I noticed about a month ago that all of the fronds were brown on the ends and some were completely brown. I cut the ones off that were completely brown and cut most of the brown from the ones that still had some green. I'm trying to figure out if these trees are dead, which would absolutely suck if that were the case. I'm posting a few pics here of one of the palms in hopes that someone can advise me on what I should do. Hopefully, there is hope here. I really don't want to…

    Trachycarpus winsan

    A two-three year old plant approximately 2-feet tall to top of frond succumbed to 36 consecutive hours below freezing with an ultimate low of 17F. The palm was under live oak canopy. The spear pulled and all fronds were brown approximately 2 weeks after the cold weather event. Approximately 1 month later at the oncoming of spring, I cut into the stem and found the green growing point. I removed all dead material and treated with hydrogen peroxide. A new spear began to grown, but aborted after about 1 week and expired.

    Hi I'm a fairly new member and somewhat new to palms even though my wife says it looks like we live in Florida with all the tropical plants around my house. The temps have been outrageous so far and we have not even been hit with July yet. I just planted another windmill Palm medium sized and did a good job except the sun got really bright and hot as I was cutting the pot away. The roots were only exposed for about 30 seconds because everything was prepped prior but now it is in transplant shock from too much sunlight. I have a makeshift roof over it and will probably leave it for about 3 weeks taking it off every now and then to let it acclimate to the bright sun. Mine …

    22f under butia canopy. Zero burn. Johnsonii is more leaf hardy than communis. Same plant took 18 last year with strong wind and partially burned, but 14f completely defoliated it, but didnt kill it. Trunk is still subterranean.

    Freeze Damage update

    Just wanted to add a little information above freezing conditions for palm trees . Many people talk about palms that are freeze hardy and they seem to ignore the problems created by stress from freezing conditions on any tropical plant. Stress that is unusual to any palm can attract many different insect problems to the palm. These insects may not kill them immediately, but several years later the palm can die.
