Some Cold Damage Observations

Recommended Posts

buffy

After surveying the initial damage of this last freeze, I have a couple of observations to share. My thermometer stated 17.9F, but I'm guessing ground level saw around 15F.

  1. Mazari 'Kashmir' is much tougher than the "very silver" Mazari palms. The silver form just got smoked. Leaves burned 100%. The meristem area looks bad. May recover, but ugly. 'Kashmir' is untouched.
  2. Piling leaves over small palms and plants as protection is remarkable. Everything I covered with leaves looks untouched. That includes avocados, some small Dypsis, Livistonas, etc. Remarkable.
  3. My Butia x Parajubaea cocoides is a disappointment. It doesn't appear to possess much of the cold tolerance of the mother. It burned at 28F last year with frost. Looks horrible.
  4. My Butia yatay x Queen looks fantastic. My Hopper Jubutygruses look great. My Shafer Jubutygrus is tough but ugly leaved. Jub X Queen, slow, but bad to the bone.
  5. Trithrinax acanthocoma and schizophylla just like to cough up their spears when in gets cold. They may recover, but they are just sensitive. T. campestris is bad to the bone.
  6. Attalea dubia is a wuss, at least at this age. Not very frost tolerant. I protected it with heat, so we'll see if size helps.
  7. All the Med. Fan Palms are coughing up their spears. Tough, but spear sensitive.
  8. Sabal causiarum is more leaf hardy than I would have guessed. Untouched. All the other Caribbean Sabals got smoked.

Hey Buffy.... thanks for the update on the freeze damage. I saw 14F at my place and it was cold for an extended time. Overall most of the plants look (thus far).

My TimHopper BxS, Trithrinax acanthacoma, T. Campestris, Nano's, Jubaea, JxBxJ, BxJ all look good!

My Livistona Rigida, Brahea Super Silver and Zamia Floridana are all 100% burnt.

All large sabals look good at a present but two small S. Urensana's were partially burnt.

Please add all this data to the freeze section, this is real useful stuff.

excellent info....you got some things there that I would love to add to the backbone of the yard. Kashmir is one that is on the definite want list , along with the T. campestris. Interesting note about the leaves, will try that with some smaller items. Very glad to hear about your S. causiarum. My big one seems to have gotten darker green but has no noticeable damage....would think it would start showing other signs if it were damaged....your report helps to boost confidence about the situation. If you get a chance...please post some pics.

Brahea Super Silver haven't been cold hardy at all for me. I've killed three that were planted out as robust 3 gallon plants.

If your L. rigida survives 14F you should be doing backflips. Also, I'm surprised your mule didn't show much damage. Mid teens is usually when they get popped.

Here's another interesting observation. Copernicia alba. I germinated a few of these from seed. As almost a joke, I kicked two holes in the dirt at the bottom of the yard and stuck these in. Both look untouched by the cold. I'm impressed. Let's see if they push some leaves.

The ice storm we had in early December caused damage and the recent low of 15F had had less to damage that hadn't already been damaged. Here are some images.

Thank Tony.

As more damage reveals itself, things are looking nastier and nastier. Gonna be a very different looking garden here come April.

Cameron,

Was the Jub x Queen a small one? Never heard much about these in terms of cold hardiness as they are so rare...

Jub x Queen is pretty small still. Mine doesn't grow like Gary's. It's been in the dirt for 4 years and is still no taller than me. It's Jubaea speed. It has some plumosity to it. Real green. The fronds show some burn. The spear just pulled easily. Lost the spear last year with far warmer temps. I just think its sensitive because of its size. If it keeps on growing, I think it will get tougher.

Buffy, could you list your plants that have survived in your yard....palms and non-palms. It would be a great list for zones 8-9 as backbone material. I think I probably already know most of the hardy palms but the dicot list might open some new doors.

It would probably be more appropriate to wait until March. I think most of this will survive. A couple will die though.

Burn on Sabal riverside and Sabal uresana. 5% to 10%. Look good otherwise.

Two species of Allogoptera smoked to the dirt. Tough sprear though.

Medemia argun is a puss.

Lost a spear on a smaller Butia eriospatha. Leaves are unblemished.

Regarding piling up leaves, I happened to protect a newy-planted Ceratozamia latifolia this way, since I had some bales of pine straw around. There was another on top to complete the igloo. You can still see ice in this pic, it was the morning after. The plant is none the worse for wear.

I guess I need to try a Sabal causiarum. And get my Trithrinax campestris in the ground somewhere sunny.

FWIW, as a side note, Livistona nitida planted only a few months ago was undamaged with sleet freezing on its leaves. Although I don't think the ultimate low temp during that event was extreme.

Hi Buffy,

Did you get long non-stop period below 32°F?

Sincerely.

It was somewhere between 13F and 15F in Augusta, GA (colder outside of town) and the damage is still starting to show.

Some things look terrific: Trachycarpus nanus and fortunei. Trachy. 'Tesan' look beautiful, even little ones. Trachy. 'Manipur' had the foliage burned off.

Brahea decumbens and moorei look like nothing happened at all. All the other Braheas look like dried arrangements.

Almost all the Chamaerops had major foliage burn, but not the Cham. humilis 'argentea'. They look great.

Sabal palmetto, minor, etonia, mexicana, rosei, uresana, 'Tamaulipas' and 'Riverside' all look fine, but the 'Riverside' has a hint of foliage burn on a couple of lower leaves. Sabal causiarum had major burn (big palms, not little seedlings), as did S. bermudana. Sabal pumos is sleeping with the fishes.

The Butias have delayed damage just starting to show: B. odorata and paraguayensis are fine, but will lose some lower leaves. Butia yatay and eriospatha look perfect. Butia purpurescens is blasted. I don't even know if it will return, but I knew it wasn't as cold-hardy as the other Butias when I planted it. The B x J (also very large) are showing a little lower leaf damage.

The Washingtonias were defoliated.....typical. They should be OK.

Trithrinax acanthocoma (12' tall) has foliage damage. I don't know how it will turn out.

Livistona nitida had total foliage burn. So did L. chinensis.

Phoenix dactylifera is a large tan sculpture. I don't know if it will make a return in the Spring.

Chamaedorea radicalis had no damage (not wrapped, but out ot the wind) and Chamaedorea microspadix had very little damage.

Nannorrhorops ritcheana had a little burn on some lower leaves.

To put this in perspective: other plants that had foliage burn (that shouldn't) were various Azaleas, Osmanthus, Black Bamboo, Michelia, and most of the Eucalyptus. All the Cycads had moderate to total foliage burn. Most of the Citrus will defoliate as the weather warms.

I think the cold was only part of the issue. The front came in with a 30mph wind that freeze-dried everything exposed to it. It was the worst cold wave here in probably 20 years.

Could you give us your cycad list?

Thank you.

Cycads that I am growing:

Cycas revoluta, panzhihuaensis, taitungensis, revoluta x guizhouensis, revoluta x taitungensis, guizhouensis x panzhihuaensis

Dioon edule

Zamia integrifolia (floridana)

Ceratozamia hildae (but I covered this one)

The picture is of a pair (female and male from left to right) of my large C. taitungensis. This is an old picture. The trunk of the female on the left is now about 8' tall.

Thank you,

With 8' tall trunk how old is your female cycad?

Do hybrid of C. guizhouensis are more freeze senstives?

How did you cover your Ceratozamia?

Last question : for a many hours freezing temperature occured?

Thank you in advance. Hope all your cycads will flush soon!

Both the male and female C. taitungensis were planted the same day in about 1992.

The C. guizhouensis hybrids lost their foliage at about the same temperature as all the other Cycas.

The Ceratozamia is small (about 15" high), so I just put a bucket over the top and then wrapped it in flannel sheets. The only heat was from the ground.

We were below freezing for about 36 hours, but the wind was howling. It was an awful night and day.

Most of the Cycads will flush in mid to late March. Thanks for your interest.

      Hello PalmTalk!
      There is going to be a short introduction first.
      My name is Yahor though I prefer you call me by my username and I am from Staten Island, a borough of NYC.
      I don't feel comfy telling people my age, but I am 12-16 years old.
      I first got my interest in palms when visiting Jacksonville Florida last year.
      I want to start growing them.
      So the reason I am making this post is something that has caught my eye for a while.  According to Wikipedia, on the page about NYC's climate, the climate data graphs and classifications section show that  areas of NYC might be in zone 8a.
      LaGuardia has 11 F (-12 C) as the minimum for January.
      Belvedere Castle in Central Park  has 9.8 F (-12.3 C) as the minimum.
      JFK has 10 F (-12) as the minimum.
      Sorry if the pictures look bad
      I find the emotes on the forum funny

      Looks like that “dip in the jet stream” is coming our way...so far I see two days/nights sub-freezing with most nights into low 20’s F and some upper teens. I’m off tomorrow so I think I’ll do a little prep but not like past winters. As I said earlier, I want to grow cold hardy palms in normal NOVA winters without overdoing it on the protection. Anyway, the new Trachy F. will get well protected, as it should for a winter or two with an umbrella and a nice layer of burlap and frost cloth on its cage with lights on the ground around the trunk and up to the crown, just a matter of inches...but everything else is going to get protection lite. The established Trachy will get some lights up the trunk (for looks) and on the crown. Same for the Brazoria. However, the Brazoria will get an umbrella over the crown, anchored with a shepherd’s hook and a blanket of lights on the ground, though a heavy rain will turn into a river around the Brazoria so I may have to improvise a bit. The Medi gets minimal as well. Sounds like a lot but compared to past winters, it’s definitely a pullback.
      Will send after pictures tomorrow...
      New little Trachy will get babied but that’s necessary:

      Established Trachy and Brazoria get some lights and the Blue B gets an umbrella...


      The Medi is ready...it has a blanket of lights on the ground but I may use cover if I have to...will wait for a forecast in the mid teens...this is the palm that is going to be most tested...

      These guys laugh every time I do this...no protection here...


      Honestly, the Needles, McCurtain and Sabal minors give real meaning to the term cold hardy...they truly are great palms for this NOVA climate.

      Pretty sure this is squirrel damage...

      I noticed several fronds drooping and thought it a natural shed and this was part of the process, but the “ shed” was painfully asymmetrical. Upon closer inspection, I found this! It gnawed the underside of the petiole, thus causing the collapse.

      Tell you what, squirrel pot pie sounds great about now. The symmetry of my palm is being ruined. It hasn’t hit the upper third...yet but I’m sending out a dinner alert for all those red tailed hawks that are visiting for the winter. Honestly, of all the things that could happen...mulling splint supports...maybe a baffle (which should really add to the beauty of my palm) any other suggestions?

      I see some people say Dypsis Lucentes usda zone 10 and up.I disasagree with that at least here in Florida.
      In St Augustine by Aligator farm entrance you can see many of them.I talked to the zoo and they told me they planted them maybe 15 yrs ago as 5-7 gallons by now they are tall maybe 12 feet or more.You can see them from A1A. But also you see some in downtown around the belive or not.This is usda zone 9a .But if this is not enough,I live in Jacksonville at oceanway which is east of 95 ,we have on Pulaski rd zip code 32218 by church for minimum 10 yrs  about 10 -12 feet tall. planted right by entrance the wall.  And if this is still not enough at Jacksonville Airport at Hilton has at pool backside of the building w/o any protection beside it planted right by the building.So I think if you place it on sunny side and close to building it can tolarete all the way to Jacksonville. I don’t have any idea about 8b zone like west of Nort Florida or Ga …Also I know a person listed close to Jacksonville airport she planted a Dypsis decaying “ triangle palm “ back in 1990 right by her house.It’s made it eversince and it’s way taller than her house.She protected at beginning heat pad etc .She has some photo at palmtalk . I have 2 of them I never heated them ,but covered however I can’t cover anymore they are out of reach .Over 12 feet or so.I got them from Home Depot 3 or 4 years ago.Even leaves get touched they come back nicely.Mine not planted by house but by fence and it get early sun till late afternoon sun…
