Alphabetical Sorting
by PALM MOD- 1 follower

Matt and Everyone, FYI --- I have switched the default sorting in this forum to sort topics alphabetically per Matty's suggestion. Please be aware that the options for sorting are always available on all the forums at the bottom of the page. You can sort topics in any number of ways. Alphabetically by topic, topic starter, last poster, etc. Or chronologically by last post, topic start date, etc. Check it out. So if you prefer checking for the most recent additions, just sort that way, by last post, from the botton menu.

Data Reporting
by STEVE IN SO CAL- 20 replies
- 14.2k views
In order for this project to be successful, we need the following info... Temp, duration below freezing(a good guess anyway), microclimate(under eave, down in a windless hole,etc) and VERY important: Plant size !!! A 24' box sized plant will take considerably more cold than a 1 gal size. If you look at Mattys and Geoff Steins posts, they are providing whats needed(others are too, just using these as examples) Comments like"my stuff looks great" will certainly end up on the editing room floor.

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 …

Something Positive 1 2
by PALM MOD- 77 replies
- 29.6k views
Let's salvage something positive out of this disastrous California weather. While the effects of the recent cold snap are still fresh in everyone's mind, let's try to document some info about the cold tolerence of various palms. Especially some of the newer introductions that may not have much of a track record. This will be far from scientific. However, it may be useful. Let's try and keep it data oriented, as there are many threads already describing the grief and horror of this devastating weather. Feel free to post pics to help document, or mention if you are referring to a small or mature specimen, or other relevant info. Add other palm species, or post your expe…

What to do with this info? 1 2
by PALM MOD- 47 replies
- 21.4k views
Now that we are getting all this great info, what do we do with it? Should we allow it to stay open, and let those in Texas or Florida contribute, if/when they get zapped? Should we try to condense it, and try to create our own Hardiness Guide to Palms? What do you all think?

chmd 0000 - Cold Hardiness Observation Master Data 1 2
by kinzyjr- 5 followers
- 78 replies
- 14.4k views
Overview The PalmTalk forums contain thousands of observations on the cold tolerance from a variety of locations and climates. One of the primary difficulties in determining cold hardiness of a particular species or variety of palm is that observations vary greatly, even at the same temperature in the same location. Therefore, hardiness can be more accurately expressed as a probability rather than in absolutes. The goal of the attached list is to more accurately calculate the probability and degree of damage one could expect from a freeze on a particular species or variety of palm by consolidating the available data into one document. This list is provided …

recovery 0001 - Cold damaged palm care

Help, please: what is the recommended application mix-ratio for Captan 50WP for bud-drench, trunk and trunk-base-root treatment for post-frost-damage/cool-wet-spring fungus avoidance? I have been told to alternate two treatments of copper and Captan. The Copper (SouthernAg liquid concentrate) has the mix rate, but the Captan 50WP (AgriStar) does not. Many forums recommend the Captan for prophylactic fungus treatment for the Mexican Fan Palm, but none of the manufacturers* have a mix rate on the label for palms - only for fruit and ornamentals. Two local palm sellers recommended the minimum mix ratio on the label. Also: Any position on the efficacy of hydrogen peroxi…

A while back I came across this web page that gave zone ratings for palms and select cycads.

2010 2010_01 - Cold Winter In Oregon
by Ryland- 6 replies
- 3.4k views
Now that there has been some time for damage to manifest in my palm garden in Oregon, I'm going to share what made it and what didn't. Almost all of my palms were very young, many of them still with strap leaves, since I had only built the garden a year and a half ago on a very small budget. This being said, my palms were probably not quite as hardy as would be expected of the same plants at a more mature stage. However, all of the palms were protected with a layer of leaves around their bases. The winter was the coldest in S. Oregon since 1990, with a low in the valley reaching 8F. I recorded 12F for the low at the garden. What survived: Trachycarpus fortunei - …

Here in Maitland (northern suberb of Orlando) we had 8 nights below 32 F during the recent extended freeze event. Of these, 6 nights were in the 20s (28,28,27,26,25,29). Here are some photos of the damage my palms have received, taken today (sorry about the less than optimal lighting). Roystonea borinqueana, almost 100% defoliated. I expect it to come back just fine.

Hello, new to this forum and palm trees. Thanks for all the insightful posts! I'm located in Hattiesburg, MS (zone 8) and received severe burn on 2 Phoenix sylvestris(3 foot of trunk)and 1 Phoenix canariensis (2 foot of trunk) despite some limited protection. We had at least 3 nights of 15-16F weather during the recent snap. The only positive news is some green is still present on the emerging center buds. I was told to leave on all the dead foliage for added protection as there may be a chance of recovery when spring/summer arrives. Really hope so as they have done really well during the prior 2 winters. I tied up the dead foliage on the trees to help shield the cente…

2010 2010_12 - Frost/cold damage from record December 2010
by PalmatierMeg- 6 replies
- 6.4k views
Yesterday (1/2/11) I photographed some of the damage my gardens sustained from my record-breaking cold December. I tried to protect the most sensitive small palms but when the last arctic front rolled in on 12/26/10 I was out of town, so everything except the Cyrtostachys (which I stashed indoors) was on its own. When I got home on noon Dec. 27 I ran about covering stuff till dark. Even so, some palms are pretty beat up. In lieu of inklings that my colder winters may be here to stay (no political commentary intended or desired) I am evaluating future gardening endeavors. Adonidias on east side of lanai. Too tall to be protected. They survived last winter and should thi…

weatherbug waetherstation about a mile away read 31 as low. I placed a digital acurite suction cup type on the ground in the middle of the lawn. It read 27 as the low. Frost all over the lawns and roofs. So far, my insulation for the palms looks like it worked. Jubaeopsis no damage, Dypsis lutescens no damage. Unprotected Alocasia looks like wilted lettuce. Suprisingly, Hass avocado looks fine.

Hey! new to the site and not really sure where to begin: finally decided to just make a general post about cold hardiness with palms in NW FL zone 8b. My botanical interests started when I fell in love with the lush northern canopy trees living in Illinois. Moving back to Northern Florida (where I had lived as a child) though, my interest in growing palm trees just took off. After moving back in 2007, I have had a long list of palm and tropical plant endeavor's with many of which never pulled through brutal zone 8b winters. Here's some detailed experience I've had with some "hot" species that are attempted to be grown here frequently. Chinese Fan Palm: F…

I don't know that this will prove of value to anyone, but here's the info: Winter 2013--Veitchia Merrillii, anyway Christmas Palm---potted that year from seed. in plastic 16 oz cups, 2 leaves. Put in an enclosure, 3 X 6', with a single layer plastic tarp, and a clamp-on 75W bulb, this arrangement under a 22' high overhang. Temp dropped to 19 deg for about two hours---no damage. This was the coldest of quite a few below freezing nights. July 2014, these are in larger pots now, and have 6 leaves. On the other front---Pigmy date, in 3 gal pot, no cover, four trees in pot, pretty large leaf array. This sitting under a 20' overhang, in a shallow entryway--two trees …

Two nights in a row of freezing temperatures. Had a group of large potted palms that were stored in my wooden shed. A few were going in the ground this spring. No added heat in the shed. Outside low temperature estimates were 30-32* first night and 25-27* second night. First night was a short duration of freeze, second night saw about 12 hours of freeze. Damage report for palms in shed (POTTED):Pritchardia maideniana overgrown 5g- 100% defoliation+ spear pull ,2 Dypsis saintelucei overgrown 5g- 100% defoliation, green petioles, solid spears, 2 Pseudophoenix sargentii overgrown 5g- 90% defoliation, green petioles, solid spears, 2 Ravenea sambiranensis 5g- one with zero da…

A few of my palms did have some damage, one Butia had a lot of browning (it was covered with a bucket), another Butia had tip browning (it was covered in a large pot), and my Mediterranean Fan Palm had a lot of browning on random places (covered with a wooden structure and a tarp). My Needle Palm and Windmill Palm appear to be fine. The windmill had a tarp over it and many layers under and the needle had no protection. No heat was applied to any of these palms.

Now that it's July I wanted to report in on losses and survivors in the January 2018 freeze. I had 5-6 consecutive nights below 20F, with absolute lows of 14F and 13F. Highs in the low-mid 30's. All plants fully exposed, no canopy unless noted. Ground froze to at least 2-3" in many areas of the yard. Most of the results are somewhat expected, I did not protect anything as the severity of the freeze caught me off guard (it was forecast for low-mid 20's here). Palms in the ground: Butia odorata (mature) Silver form, 50% defoliated. (5-7 gal) - Smaller silver Butia 50-100% defoliated but survived without aid. Many seedlings were killed. Butia sp. (5 ga…

Worried all night about my royals, foxtail, Alexander, and robellinii’s from last nights freeze, wasn’t overly concerned with my duo headed sago which pulled thru well. Have to say that I’m impressed of how the Alexander, the foxtail and robellinii’s pulled thru undamaged. The royals on the other hand has some burnt foliage which I sort of expected but the palms themselves survived. We’re expecting one more freeze tonight and I’ll have my fingers crossed. By the way, my t-stat here in Deltona was at 31° at 6:10 am. The weather Channel has us expected to be a low 29° tonight.
