Up here you can drive from coconuts thriving to temperatures in the teens within a 30 min drive. It is horrible. Goes from a 9a climate to a 10a in like 10 miles or less

Here’s the Greenhouse I forgot which one in Cincy forgot to post this! Man, that is a huge queen sago palm!!

Copper is a great fungicide too. I wouldn't worry about liquids mixed with the fungicide, but I wouldn't pour or spray water into the crown without the fungicide. Hydrogen peroxide is a great fungicide too, and degrades to water and oxygen in the presence of fungus (thus the bubbling). One reason people suggest H2O2 is because it bubbles up, and you can easily see if fungus is present. I think a good squirt in there occasionally is a good safety measure. I used about 5 x 32oz bottles of H2O2 and then ~2.5 gallons of Daconil mix on the 6th (I think) an am doing another dose next week.

I just keep on buying seeds, I have another 5 orders out at the moment just waiting to get into the country and clear customs, and one in the Australia post system that should be here on Monday. Richard

I sprayed a bottle of bonide copper fungicide in the crown, around the crown, and on some of the lower frond areas yesterday. I have to admit I do have concern spraying so much liquid in and around the crown wondering if it will negatively affect it at all as far as the dampness. Although I guess it gets soaked when it rains anyways, and it was around 80 in full sun today. Today I also added some 5-1-1 fish emulsion in with my moral watering. Good idea on marking the spear, I’ve done that in the past to will do that tonight would you still recommend after a bit putting some peroxide in there periodically?

They get even more as they get bigger. Harry

Figured everyone could use some good news. Pritchardia thurstonii was able to weather the storm under coconut canopy and shielded from wind slightly by the lanai. It is opening the damaged leaf in the photo and the another spear is coming out. That said, we do have another front coming and that might finish it off. At least it is still in the game, though.

I was able to force this color with 23 degrees but i don't think I’ll be able to maintain this look.

My B. Alfredii palms after the recent florida freeze. I'm in Orlando. Had these in the ground for about 9 years. Not very cold hardy if you ask me. I went to lucas nursery and they have several that seemed burned as well. They trimmed all of theirs fairly aggressively after the storm. Most of them have 4 or so fronds on them now. Anyways, I sprayed copper fungicide on the center spear more so into the center of the crown. Hoping that helps. Most worried about appearance since these have been sloooooow growing so will take forever to replace these crowns.

@sacts those look a lot like my 5 big Alfredii. I didn't have much if any damage in the past 7 or so years, down to ~27F several times with heavy snowlike frost. Mine took mostly light leaf burn at 24.4F and frost, and did take nearly a year to totally grow a new crown from that. I'm guessing they are going to look kinda ratty through mid summer. I fertilized mine 2 weeks ago, hoping for quicker recovery. I also did hydrogen peroxide and then Daconil into the crowns, but not copper...yet. I will probably cut off the lower fronds in a week or two. That's partially for looks, and partially to make sure there's good airflow and sunlight into the green bit left in the center.

The wind made the difference this time. 23F is one thing, but couple it with 30-40MPH winds... 🥶

Temperatures in the Orlando area this go-round were ~24F in most spots. Hope for a full recover for all of them.

Love buying some cold tolerant palm seeds off of @Bigfish. Great experiences buying off of him and speaking with him at meetings when he's able to come.

@Golden10 I like the idea of the hydrogen peroxide and Daconil crown treatments too. A simple squirt from a $2 bottle of H2O2 could prevent [or cure] aa crown fungal infection. Since the crown is only a foot off the ground, it's easy to reach. I'd also mark the new spear horizontally with a sharpie, across it and the fronds next to it. That way you can easily see if it is growing. It may not move much for several moree weeks, but generally should be steadily growing. Even if it is only 1/16th of an inch per week, some steady movement is a good sign.

Rhy. gigantea, var. illustre. A rescue from one of Home Depot’s 1/2 dead 1/2 price shelves. Purchased in FL 2 years ago. Been a long, slow nurturing process. First time blooming for me. Humidity in the house is very low in winter and am surprised it bloomed. Life is better for this orchid in the summertime, where it can luxuriate outdoors, in all the humidity and balmy air.

I also had a couple copernicia that were potted and infected, one fallaensis and one hospita had spear infections. They were fine till I put them in a shady spot. Dew is everywhere here for a good part of the year. Sun burns the dew off, if its direct for several hours. I treated them and moved all my potted copernicias into direct sunlight and they responded with good healthy growth. I have one cuban copernicia in mostly shade, a macroglossa and it just sits there barely grew in 4-5 years. A second same sized one I put in direct sun 8 hrs and it is 3x the size. My experiences with the cuban copernicias( I have eight) is they hate shade plus being frequently wet with dew. Wet soil, they are fine, wet leaves/bud is a no in shade. Some of mine near irrigation sprinklers have mold spotted on oldest leaves. They love rain but they also want the crown to dry out. Once they get some size up off the ground, dew is less an issue, and they may be fine. But overhead water, lack of sun and incessant dew in florida has led to spear pull on mine. Overhead water is not a problem when in full sun, as the bud consistently dries out.

Guidance has trended colder in the past 36 hours or so. This is shaping up to be a freeze for the Panhandle. NWS currently forecasting a low of 33F for Monday night. Looks like it may warm up pretty quickly after that before getting cool again to start the month of March. Being cold in Florida multiple times during the winter season is not a new thing. Y'all have gotten lucky more than anything in the past decade down south. I would be grateful to live in the areas of central Florida thats been trashed on so much in this thread. I am still thankful to be located in NW FL, where many palms can be grown. Sometimes it pays to just be thankful for what you have instead of being upset about what you cant have. My Queens are fried, my bizzy might not make it, my lady palm spear pulled, my washies are burnt, but... here is my super mule, looking like winter never happened: For that, I am thankful.

Hey there yall! Long time no post and see! This is ChicagoPalma here, just cannot log onto my old account and I need some immediate assistance here! So far, I took off the enclosures for the palms, and this year instead of making it out of fosmboard, I made it out of reflective bubble wrap and chickenwjre. So far, the small windmill did amazing, but the larger one did horrible. The spear pulled and I am not sure what to do atp. Anything anyone can help with?

Today it caught my eye that I could take a photograph of my palms when it’s raining and see the raindrops in the photograph.

This sheet is preliminary since a lot of the stations haven't reported their final numbers yet. We do need something to refer to for the time being, so the attached sheet is the available numbers NOAA has compiled for the dates 01/30/2026 - 02/08/2026. There are two sheets in the file - one that is mostly sanitized and the second sheet that has all of the available stations with any reports since the beginning of the year. Sheets like this are how the impact freeze maps are created as well. beta_Feb2026_AdvectiveFreeze.xlsx

Please tell me this is normal like the specks on D. Lutescens. It's on all the petioles, I don't see it on anything else, and I remember scraping and rubbing my first Lutescens almost raw trying to get them off before I learned they were part of the plant. This is one of @NOT A TA's sprouts, so it needs the good palm god vibes.

Yeah, Tennessee and North Carolina's climates are pretty similar (except by the Coast) The only major difference is you guys lack North Carolina's maritime influence. My area of appalachia I would say is pretty interesting we are borderline Dfa/cfa and we are also the beginning of the Hickory- oak- pine forest ecosystem which is part of the Southeastern mixed forests So we are pretty much the gateway to the south. We live in a pretty borderline area lol.

Yeah. If the Carolina one leaves out Tennessee for not having "Carolina" in its name and Mid-Atlantic one leaves out West Virginia for being landlocked, that opens up the door wide for an Appalachian one. If enough people in Illinois, Missouri, Kansas, Arkansas and Oklahoma really want one but don't already have and aren't formally organizing an Ozark one, we could even do a broader Upland Southern one including those five states plus the Appalachian quintet, with a meeting point in Little Rock in odd-numbered years and Lexington in even-numbered years (or vice versa). I just thought little of Pennsylvania because although it's probably the most Appalachian state besides West Virginia, their portion of Appalachia tends to have a continental climate that would make it hard, unlike Philadelphia which is more subtropical than New York city, and also figured Pennsylvania would surely be included because it's not landlocked like West Virginia is (thanks to the Delaware Bay).

I just got done watching the Palmcast with @Sabal Kingand @teddytn talking about experimenting and not listening to people say what will and won't work and immediately throw out a feeler because I read these hate swamp. The seeds are slowly popping so I'll keep a couple but priorities are priorities....

Updated for 2026! Note that Gavdos is missing the epic cold spells of 2022 and 2021 so its definitely lower. The Port of Rhodes is also missing the mild winters of 2025 and 2026 (so far) and its definitely higher.

Inverted "v" 2/15/26

They look a little burned but they will be fine. Sometimes palms respond with a little extra, my alfredii seemed to respond well to getting hammered by hurricane milton. These are just 2-3 degrees more cold hardy than cocos. WHen we say cold hardy that means death not leaf burn. My sympathies for the leaf burn, it will take a couple summers to fully recover. My alfredii in full sun puts out about 10 new leaves a year, shaded ones put out about 7.

Palms from @teddytn arrived today and they look amazing!

Here are the 2 mature Coconuts growing across from Fashion Square Mall at the former smashburger restaurant. The one on the left is totally brown but the petioles are still green. The one on the right actually has a couple leaves in the center with green. These palms are less than a mile from the Executive Airport which has an official NWS station and recorded 24F. If both or one survives it will be the new I Drive coconut.

I'm sure you will have a great visit and see plenty of beautiful palm species on Oahu. But just to inject a pinch of wretched reality, Oahu is being attacked by swarms of coconut rhinoceros beetles. They were introduced around 14 years ago, but the state's response has been pathetic. 'Too little, too late' does not begin to describe the bungled half measures taken. Large beetle populations are firmly established across Oahu and there is no realistic strategy to eradicate them. The department of Ag has stopped monitoring surveillance traps around the island because every region is now infested. Hundreds of large coconut palms growing in beach parks have been cut down to prevent the towering dead trunks from falling on people as well as to destroy any larvae that might be developing inside the rotting trunks. Driving around you will notice the characteristic V-shaped cuts to palm fronds that signal that the end is near. I think the public botanical gardens have not been hit hard, yet. But the outlook is pretty bleak. Good that you are visiting now. In five years there might be many fewer palms to see. Here is a map showing the latest infestation data. The map on the left shows no detections along the mountain chain, but that is only because nobody placed or monitored traps in this very steep terrain. The right panel shows color coded population densities with darker blue being worse, but the data are pretty incomplete. The beetles are pretty much everywhere. If you can possibly arrange a free day on your trip, I recommend a quick hop over to the Big Island. Depart Honolulu on the first flight of the morning, arrive in Hilo before 9, then hit four or five private palm gardens you see on PT, plus Hawaii Tropical Botanical Garden 10 miles north of Hilo, fly back to Honolulu by 7. You will be very tired, but you will see great palm collections. CRB arrived on the dry Kona side of the island two years ago, but so far has not been sighted on the wet east side of the island.

I am not sure what they should've done, but I don't love how they handled your purchase either. It seems like they could've at least discounted you a portion of the purchase price to account for the cold damage.

I have never planted in the winter either, but yes, my backyard has a very large tree in the center of it that provides a good deal of shade, and I think that makes it a weaker spot for palms that prefer full sun. I think the copernicia I got was harder for me to care for because it was potted and infected and the combination was not good. I'm sure it also didn't help that I didn't have a great full sun location for it.

Is it just me or does the central spear look discolored? Seems an unusual dull green/grey with the black spots and white mold?

There is A LOT to do on O'ahu in the world of horticulture and landscape...pardon my very long post here but Honolulu is a big city, O'ahu is a good-sized island, with several diverse climate-types, and this is just some of what is there for your botanical enjoyment... The single most important place for you to go is Lyon Arboretum, part of the University of Hawai'i, at the top of Manoa Road. Truly spectacular and you'll probably want to go up there more than once. The late great Ray Baker along with Bob Hirano were the driving forces there in the latter 20th century, establishing amazing collections of palms, Heliconia and many other plants in this perfect, rainy greenhouse of a place. You can really wander into the deep tropical forest there, and you can see things like Amherstia nobilis and lots of other rarities thriving. There are also a lot of plantings on the UH campus further down the valley toward town. For a flip-side experience, you should go to Koko Head Crater and botanical garden...this fascinating crater has a semi-desert climate with one of the best collections of Plumeria on the planet. Also many other tropical plants that thrive in such a dry, hot environment (Madagascar, etc.). Very useful to inspire you for your Arizona garden. Very importantly, remember to bring water with you if you go there...water/beverages are not available, and the dehydration factor may remind you of Arizona! Foster is important because it's a very old botanical garden and thus has some very large specimens of many tropical palms and other plants that represent early introductions. I lived in Honolulu in '88-'89 and would often visit Foster Gardens, it was the first place I ever saw the beautiful Satakentia liukiuensis...I was really transfixed by those palms and I'll bet they are really something after all these years. You might also look into Wahiawa Botanical Garden...interesting because it is located upland, in the middle of the island (near the Dole Plantation). Also Waimea Botanical Garden on the windward side of the island, I remember that being a very nice walk up into that valley...but not sure if it's worth the ticket price considering how many other options you have. To me some of the best experiences are to be found just wandering in town and through some of the old parks like Ala Moana, and Kapi'olani. If you walk down along Kapi'olani Park (on Kalakaua Avenue) by the Aquarium and toward Diamond head it's a really pleasant experience parallel to the beach and it's fun just to explore the neighborhoods flanking Diamond Head, just to look at the residential landscapes. More Singapore Plumeria and Tahitian Gardenia than you can shake a stick at, and lots of beautiful uses of lava-stone walls and other Hawai'i-style landscaping elements that may give you inspiration for your own landscape back at home. Other well-heeled areas that feature very nice landscaping and good for an easy driving tour include Kahala (on the other side of Diamond Head, this is where Magnum P.I. was largely shot), and up on Tantalus and Makiki Heights (Round Top Drive, Makiki Heights Drive), very jungly area with large estates hiding behind some wonderful plantings, you can work that area in with a trip to Manoa. Through this area and going up to the Pali, you'll see gigantic pothos and Cup of Gold vines snaking through the trees that will blow your mind. There is also a botanical garden at Tantalus but I haven't ever been there. As far as public-facing landscaping palms are concerned, Pritchardia pacifica in particular is used all over the place, particularly in commercial and hotel settings, and seems to reach its visual zenith in Honolulu's climate, and you may really fall under the spell of that palm. Honolulu is famous for its huge banyan trees and you will also see incredible Monkeypod (Samanea saman) trees wherever there is room for them, along parkways, especially Moanalua Road/Hwy and at the Moanalua Gardens. If you have time, try to include the historic areas of downtown. Fort Street Mall, University Avenue, King Street all have wonderful old plantings around the historic buildings, lots of mature Pritchardia pacifica and Ptychosperma, et al. in random plantings in the commercial center. Also lots of beautiful red and pink ginger and Heliconia all over the place around Honolulu. I assume since my last visit (I think 2008) many new tropical palm and other plant introductions have arrived and thrived in landscapes around the city as well, especially in hotel landscapes. I remember noticing during my last visit that in particular Areca vestiaria had become more common in landscapes there. In Waikiki proper, you must wander, wander, wander, especially through the larger hotel properties, and go to the Royal Hawaiian Hotel and see the Banyan filled with its crowd of garrulous Mynah birds and some really magnificent old plantings of Ptychosperma macarthurii up against the hotel walls. The landscaping there epitomizes old gracious Hawai'ian landscaping of the early 20th century, and everything is very well maintained in the "Hawai'i style." Keep in mind that Honolulu enjoys a really interesting convergence of mostly Pacific/Asiatic cultures, Polynesian, Japanese, Chinese, Filipino and others, and so there is some real landscape diversity based on those cultural traditions. The East-West Center Japanese Garden next to UH is well known, and the Hawai'i Int'l Airport's cultural garden (yes, in the middle of the airport!) was designed in the early '60s by famed Landscape Architect and author Richard C. Tongg and hopefully you can work that in with your arrival or departure. And for just the natural beauty of the island, don't forget to drive out along the Kalaniana'ole Hwy to Makapu'u Beach (famous for the sand that will be deposited in your swimsuit, and you can see Maui!) and further along, the view of the Ko'olau Mountains in Waimanalo is truly spectacular and should not be missed. If you take that trip (which could include Koko Head), you might also visit some of the nurseries along that route. Just a few I remember are nurseries like Ni'i Nurseries (Charles Ni'i Nursery and also R&S Ni'i Nursery, there are two of these) above Hawai'i Kai near Koko Head. Frankie's Nursery (mostly tropical fruit trees but also some ornamentals) in Waimanalo is very well known, and may be worth visiting for a wander. If you're interested in Plumeria there are some major nurseries like Jim Little Plumeria Farms. Many of these nurseries will ship to the mainland as well. There used to be quite a few well-known mom-and-pop nurseries specializing in orchids, anthuriums, etc. around the island and I'm not sure how many of these are still around. But you might just google nurseries and call around, and I'm sure there will be a good selection to choose from. While many people associate Honolulu with coconuts, banyans, breadfruit, monkeypods, Plumeria, Anthurium, orchids, gingers, Cordyline, et al., Honolulu is also famous for its flowering trees, and you will likely see some nice ones in bloom in April, including Pink-and-white Shower (Cassia javanica), Rainbow Shower (Cassia x nealeae), Silver Trumpet Tree (Tabebuia aurea) and the Primavera (Tabebuia/Cybistax/Roseodendron donnell-smithii). If you can't tell from my verbose listing, there's a lot to see pretty much everywhere you go!

Yesterday, the girlfriend got me a European Fan Palm as an early birthday present. I repotted it this morning. This is my first time growing one of these.

This youtube video might give the doubters some clues: https://youtu.be/hfMNbc8wjq4?si=rLLEKdiBbptPeFMo

I have never planted in winter, roots dont grow then. Best time to plant in my area is in the beginning of the wet season, roots grow quickly in the wet heat. Is your back yard part shaded and the front sunny? I had a 15 gal C fallaensis get spear infection a few years back when I had it in 2/3rds day shade. I treated with peroxide and daconil once a week for 3 weeks and put it in direct sun 2/3rds of the day. Both C Fallensis and B Alfredii dont like shade and that may effect immunity from pathogens when injured. Sometime you just plant out a lot and the weather hammers you before the palms get adapted. A transplant is no doubt less cold hardy than an established palm. This year winter looked like the coldest in decades for some florida growers. I had 3 royals killed in 2010 along with some other 10a palms. A couple year after I put in (2) royals with 3-4' trunk and they are 40-45' today and seemingly take the cold well. Radiational cold(low wind) means temps at an elevation of 15' are warmer than near the ground at 4'. For tolerance to radiative events, there is a window where palms will be vulnerable but after the grow and the bud rises, they tolerate the radiative fronts better. I changed my approach after having half of my palms killed in 2010. More cold tolerant palms can help protect the less cold tolerant ones in buffering wind and in improving the trapping of heat down in cold events.

Honestly I think it would be a great idea!, just organizing it is the hardest part. I would love to start a mid Atlantic palm society but I don't even know where to get started. If you started a Appalachian palm society I really think you should also include the south central part of Pennsylvania it is very much part of Appalachia Culturally and Geographically we are very similar to southwest Virginia and West Virginia.

If the fronds are taking major damage the spear will too when it gets above ground

Foster BG should definitely be on your list. Paradise in the middle of a concrete jungle! Lots of Lodoicia (double coconut) trees to see. aztropic Mesa, Arizona

White triangle

Nice double roebelenii! I almost bought one too - $70 at the orange store, right? I settled instead for a $35 foxtail and a $10 Dypsis lutescens. I managed to get both in my Nissan (somehow).

Appreciate the advice. For the time being I will watch the condition of the spear I guess. Assuming it will turn fully brown or mushy if badly damaged. I will try the fish emulsion as well

I would not fertilize with NPK prills till june. For now you could use fish emulsion(5-1-1) and dilute humic acid once a month. THe roots have been cut so they will have to regrow, no sense in dumping NPK on the palm. I think it may be OK, what was your low temp?

They are more solid and robust looking and a different colour new leaf in comparison to macrocarpa, a good healthy macrocarpa you can’t go past though for the glory they are known for! Here’s a nice pic of a macrocarpa. Richard

By the looks of it,they'll probably revert back to that ugly blue color... 🤷‍♂️😆 Not necessarily a bad thing.👍 aztropic Mesa, Arizona

Cibolo TX Post Winter storm report: Temps in my neck of the woods hit 19F or 20F, with some freezing rain. As usual, I think the freezing precipitation was the bigger problem. C. radicalis with East Northeast exposure and partial overhead protection from the eave of the house. P. dactylifera was almost immediately dead. It was about 3 ft in overall height and very healthy going into this event. I covered it, but not until it was already wet. So it's spear pulled almost immediately after the freeze. It's leaves were brown within a few days. I cut the trunk down and there was no living tissue left, despite treating it with hydrogen peroxide within a couple of days of the ice. Butia took a little longer to show damage. It was covered with a large patio umbrella, but it blew off during the storm. It was a couple of weeks before the newest leaves started losing color. Spear pulled, and I have been treating it with H2O2 as well. No signs of a new spear yet. Even my S. mexicanas (No protection) have a leaf or two that have lost their color. This surprised me: My Washingtonia that grows like a weed looks pretty much perfect with no protection: Not all Washingtonians are created equal though. This is what another one just a couple of houses down from mine looks like: Small trachycarpus F x Ws took no damage with a bucket to cover them:

Here’s the one in Mt Joseph University Cincinnati, OH This was planted in 2000 it was cut down for unknown reasons by the Landscapers around 2020~ and yeah came back strong! Somerset opens at 2PM so we will check that out later!

Before I ever saw the decora along IH-45 there was one along the feeder road of US-59 north of Porter not far from my sister's place. I collected seeds from it (around 2015) and looked for it many times after but it must have been taken out with the development in the area.

Thanks for helping me out. Palms look great!
