tank Posted January 18, 2007 Report Share Posted January 18, 2007 That's good news! I am planting a couple here in Gainesville, FL this spring. Gives me hope that it stands a decent chance. Please let us know if it starts showing damage. Jason Gainesville, Florida Link to comment Share on other sites More sharing options...
Palmy Posted January 19, 2007 Author Report Share Posted January 19, 2007 Very little damage has shown up. It was glazed over with ice totally. It seemed to hold up pretty well. I would say even a little better than my queen, which suffered some damage at 15 feet tall.

PalmGuyWC Posted January 21, 2007 Report Share Posted January 21, 2007 No damage at 23/24F, light overhead protection. Now if it would only grow....one frond a year. Richard Douglas Link to comment Share on other sites More sharing options...
PalmGuyWC Posted February 1, 2007 Report Share Posted February 1, 2007 I'm sorry to report that one of my A. micranthas is suddenly showing significant damage from the freeze of 23/24F. The emerging sphere looks fine. Another the same size and planted not to far away has more overhead protection and it looks ok, with just slight brown tipping. Maybe they are not as hardy as we thought. They are both 5 gal. size. Dick Richard Douglas Link to comment Share on other sites More sharing options...
Palmy Posted February 1, 2007 Author Report Share Posted February 1, 2007 Really? Mine are both doing great. I see very little damage. Mine are about 3 gallon size and they are all doing great. Thats to bad of a loss. They are extremely hard to find for me. Hope they do alright. In the wild I hear that they take frost and sometimes snow.

PalmGuyWC Posted February 1, 2007 Report Share Posted February 1, 2007 Hi Zack, Keep a close eye on your A. micrantha. Mine showed no damage until I noticed yesterday that the two lower fronds had gone into rapid decline and it only has 3 fronds. The damage showed up in only the last couple of days. I didn't give either of my A. micranthas any protection, since I assumed they were more cold hardy. From the lack of reports, I assume not many have A. micrantha. If anyone has one, please send in a report. Dick Richard Douglas Link to comment Share on other sites More sharing options...
ghar41 Posted February 1, 2007 Report Share Posted February 1, 2007 I have one that did fine in the freeze. I am noticing that some of my palms are on the dry side, including my A. micrantha, so I have had to water more than I am used to this time of year. Almost no rain here in January.

DavePoole Posted February 9, 2007 Report Share Posted February 9, 2007 So far no temps below 0C (32F) this winter, but last year mine (4ft+) took a -3.8C (25F) drop undamaged and coped with 10 days when temps were -2C (28F) at night rising to only 4 or 5C (38 - 40F) by day. It produced 2 complete leaves last year and a new spear is currently 6" long and growing. Coastal South Devon, England Link to comment Share on other sites More sharing options...
DavePoole Posted February 9, 2007 Report Share Posted February 9, 2007 Sorry folks - I jumped in bleary-eyed thinking this related to general cold damage in palms grown everywhere, without realising it referred to the big freeze you had recently. Therefore the above is irrelevant as are my inclusions for Chamaedorea plumosa and C. costaricana. Coastal South Devon, England Link to comment Share on other sites More sharing options...

tank Posted January 11, 2008 Report Share Posted January 11, 2008 In north Florida. Low of 21 F, 10 hours at freezing temps. 3 days of freezing temps. Substantial overhead protection. Little or no frost. 15 mph winds. 90% with all mature leaves pretty much toast. As described above, damage takes a couple of weeks to really show up. New unopened spear, which is about the same lenghth as the last mature leaf, appears to be undamaged. This plant is about 4ft OA. Hopefully this one will recover in the summer. Last summer it produced 3 new leaves. Also, temps were into the low 80s(F) the week before and the new spear was pushing out. If plants do indeed "harden" off, this plant was probably "soft".

edbrown_3 Posted January 13, 2008 Report Share Posted January 13, 2008 I had this one grwing in Jax... I lost it in 99, we had a fortnight of freezes (day after day) with a low of 21 F. Like Dicks experience it succumbed later. I replanted ( a few years ago). hoping for better times but it grows real slow.

tank Posted January 14, 2008 Report Share Posted January 14, 2008 Rob, It seems this advective freeze was a bit harsher on my marginal stuff. I have Agave augustifolias that usually only show damage in the upper teens (F) showing some damage. The damage on my agaves didn't show up until two weeks later. I should note that this A. micrantha has seen temps down to 22F in a radiational freeze and showed no damage. Now the spear is looking a bit "odd" but one leaf still is looking more or less alive. The spear actually looks like it started growing again during the warm weather we had this past week. Jason Gainesville, Florida Link to comment Share on other sites More sharing options...

mppalms Posted August 4, 2008 Report Share Posted August 4, 2008 Congrats, Jason. This certainly isn't a palm to lose. I don't have a good freeze story for this one, but I can say that it is weed-whacker-resistant. One of the guys who trims our hedges decided that palm = hedge and turned this one into a stump. Why? I have no clue. But, it is throwing a new leaf after looking pretty dead for a couple of months. Jason My A. micrantha survived and has put out its first new leaf since the freeze.

mnorell Posted January 28, 2009 Report Share Posted January 28, 2009 Very small (6" tall) specimen, planted in a slightly wind-protected area. The worst so far this year being an advective, 14.5-hour event bottoming out at 24.1F. 100% leaf damage, dessication showed up about 4-5 days after the freeze. It had been fine through a similar 27F event. I assume a good spear will push as it was mulched above the crown. A community pot of seedlings placed near the output of the heating unit was untouched. Damage to the in-ground specimen was worse than on my most exposed A. engleri/Taiwan form, and was located somewhat near two other similar engleri that are spotless. For comparison: a tiny x Wodveitchia (arecina) growing in a somewhat more protected spot five feet away was untouched. I think this Himalayan "cold-loving" palm is not as hardy as we all might like to believe.

tank Posted February 17, 2009 Report Share Posted February 17, 2009 ~20F, possibly a little lower torched the one "good" leaf produced last summer on my A. micrantha. Spear appears to be fine. Nursery down the street was selling 35 gallon A. engleri's, big full plants about 10 ft OA in the pot for $200. A friend of mine picked one up one of these on one of the 80F days we had right before the worst freeze of the year. His A. engleri was under canopy and not touched. will not plant any more A. micranthas out up here. Jason Gainesville, Florida Link to comment Share on other sites More sharing options...
PalmGuyWC Posted February 18, 2009 Report Share Posted February 18, 2009 I have written off A. micrantha for my climate. Not only are they not that cold hardy, but I had one with a nice spear about to open last summer, and we had a heat wave and the spear was cooked, and that in part shade too. It had taken a year to grow the damn spear. I think they like warmer nights and higher humidity than I have. Dick Richard Douglas Link to comment Share on other sites More sharing options...
tank Posted April 23, 2010 Report Share Posted April 23, 2010 Low of 14F. 14 days straight of below freezing temps. 80% overhead protection. ~30 Plants in pots (1gal to 3gal). Left these in the cold to fend for themselves. 25 appear to be toast. Most lost all of their leaves but a few are pushing out new spears. Gonna see if more return from the dead.

Austinpalm Posted June 3, 2010 Report Share Posted June 3, 2010 Two 3-gallon sized plants in the ground under live oak canopy. Ultimate low of 16F with multiple nights in upper 20's and lower 30's. Both plants were fried but one has just put out a new spear. Nothing from the second plant as of yet. Clay South Padre Island, Zone 10a Link to comment Share on other sites More sharing options...

It had taken a year to grow the damn spear. I think they like warmer nights and higher humidity than I have. Dick Arenga micrantha at the San Francisco Botanical Garden is slow but very successful. They are planted in shady spots, have flawless dark green leaves, and appear undaunted by the light frosts experienced (probably have seen 28F minimum). They put out 2 leaves per growing point per year. Much better than A. engleri, which sits unmoving all year until it finally collapses. I think this plant tolerates cool humid nights very well, whatever its other tolerances may be. Hot and dry sounds lethal.

daxin Posted December 22, 2010 Report Share Posted December 22, 2010 My first palm planted was a 5g Arenga micrantha in Mar. 08 in my previous garden. It is facing east and backs against a two-story house. Since then it has been growing very well and is beginning to put out suckers this year. However, it is not seriously tested in terms of hard freezes. I think Dick's plant might be in too much shade and having lots of root competition. Here are two photos of my dearly missed Arenga micrantha from 2008 and last month.

Caryota_gigas Posted December 15, 2011 Report Share Posted December 15, 2011 I find this a very hardy palm in Auckland, NZ. Mine has been down to around -2.5°C many times and sits in full sun and has never been damaged by anything. Possibly the toughest palm I grow.

Sutter Bob Posted June 1, 2012 Report Share Posted June 1, 2012 Update. Had a low of 20F in January. Lost one below Italian Cypress far from house. One close to south side of house looks good, pushing new spear. Link to comment Share on other sites More sharing options...
