Encephalartos ferox
by TexasColdHardyPalms- 1 reply
- 783 views
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.

Ravenea juliette

This plant is about 6 years old and very slow.. makes a leaf a year. Leaves about 5' tall now and get a bit burned every year... but less each year. However, this year 27F for 5 hours... some leaf damage, but less than expected based on last year's damage... but no frost this time. To me the significant thing about this freeze is what did well and what didn't. This palm is almost leaning against a large, 3 stemmed Dypsis baronii seedling about the same height. That plant has lost every leaf- fried to almost a black color. Yet this one has two healthy green leaves and one with some spotting... so this plant is obviously significantly hardier than Dypsis baronii.

Majesty Palm Sees 28 Degrees (F)

So my Madjesty Palm saw 28 degrees (F) and to make matters worse it was in a pot, this is in Virginia on the boarder of zone 7a/7b and from what I have heard Madjesty Palms are a zone 9b palm. This palm has been good with no damage to 30 degrees (F) in the pot. It loved the cold as you can see!

Bassellinia

have 4 of these seedlings about the yard with moderate protection for all of them. All died after 27F as far as I can tell. Exposed to at least 5 hours of this freeze (no frost). I have had these before seem to handle temps below 25F but only for a brief moment. Guess the prolonged freeze is what did them in.

I have 2 which took 3 weeks of sub zero temps with at least 2 excursions to -4c/24.8v and 2 lower dips to -5c/23f. Some white spotting on the smaller one, the larger one looks a lot healthier. Regards Andy.

12% Peroxide as an palm crown anti-fungal
by PTRocky- 1 follower
- 1 reply
- 140 views
I was able to secure 12% Hydrogen peroxide on the internet (called FOOD GRADE peroxide). On 01-17 and 01-20 mid-upper teens in Montgomery, AL there seems to be a latent aftermath of crown rot on 5 Trachys. I thought the 12% peroxide would have a stronger anti-fungal effect but I have not used it yet. Does anyone have experience utilising 12% hydrogen peroxide on palm crown fungus, or should it be diluted to 6% or 3% before drenching the Trachys' crowns? Are Trachycarpus palms slow to respond to this treatment? Nothing seems to have occurred positively yet. I read in the internet that this recovery process could take 6-7 months (or at least until the nights are …

Ceroxylon quindiuense

Have a 4' tall specimen been growing great year round... not even a hint of damage or slowing down when temps got 120F here!! And this last weekend temps got down to 25-27F most places in the yard, though this plant is planted between two Italian Cypress... not a hint of damage.... even though Chamaedorea metallica planted under it was pretty badly scorched. Just visited nearby nursery (1 week after the 'big one'): 2 5 gal plants, 2' overall height with a tiny bit of protection from a now fried King palm in a larger pot right next to them: both have moderate to severe leaf damage from a low of 26F (no idea how long), but newest leaves and spikes look OK. Was actuall…

Macrozamia Communis and Johnsonii
by TexasColdHardyPalms- 1 reply
- 904 views
I have one of each planted beneath a grove on Butia Catarensis. The butia experienced 50-60% burn this winter when we dropped down to 13.6 here at the house with 30+ consecutive hours below freezing. While both Macrozamia completely burned the Johnsonii faired much better as it came out with new green foliage a full month before the communis. However they are both alive and well today.

Sago Palm Damage - HELP
by Mrtommy03- 1 reply
- 394 views
Hello, I have 2 sagos in my backyard (about 10 years old). I am in north Texas, and if you didn't hear, we had what I refer to as "snowpocolypse" a few months back. I tried to cover my sagos as best I could, but it was sub zero temps for multiple days in a row... Not fun. Anyways, all of the fans turned brown and I thought they died. Then came late spring and early summer, and tons of Pups sprouted out near the base... But nothing on top. I have since harvested 4 or 5 of the Pups, and they are doing great. But here we are in mid July, still no new fronds coming out the top, but still more and more Pups are sprouting. Question: Will it ever spawn new fron…

This might be another one of the "suprises". I have an overgrown 5 gal that had no cover at all, was under 28F for 4 nights and 2 of those hit 26F. It looks about like it did when this started.

Chamaerops humilis
by BeyondTheGarden- 1 reply
- 546 views
I don't see a thread for Chamaerops so here's my contribution. Green form, around 15 gal size, in ground, subject to 7 days where it only got above freezing once for a few hours (during the PNW Arctic Outbreak around Christmas of 2021 through New Years. Ultimate low of 16f. Zero apparent damage, and that was a month ago. I have a smaller one in the ground, around 1 gallon size, very small. It was covered with an upside down tote box and no heat. Also no apparent damage. I don't know what the limits of this palm are but I honestly expected some kind of damage to show. I'm impressed.

Cold damaged palm care
by smatofu- 1 reply
- 413 views
Hi, How to take care of a cold damaged dormant palm (no spear pull, no growth, no green spear). Questions to advance forum members. 1. Water the palm or not? 2. Cover the top when raining or not? 3. Cover the palm at night with a blanket to make it warm and potentially to promote growth? 4. Fertilize? 5. Use copper, hydrogen peroxide, or both? For the beginners: - if you cover then use something breathable, like a paper bag. Never plastic because you may cook your palm, - if you fertilize, don't fertilize too much and too close to the trunk. Thank you in advance! …

Aiphanes minima
by Jason in Orlando- 1 reply
- 3k views
From February 2012 advective freeze. The ultimate low temp is unknown. I had a 15 gallon A. minima left outside when the forecast low was to be about 37F/2C. Cold front came through about 4am local time and dropped the temperature from about 40F to near freezing in two hours with high winds. Water in bird bath was frozen. There was no frost. The palm had no overhead protection, but it was sheltered from the NW wind by the house and the orchid shadehouse, as well as the fronds of other neaby palms of similar size. A week later there is no damage other than some minor leaf spotting on one of the more exposed fronds and some slight burn. Temperature was likely not …
