Sounds like 30F+ worth of protection! I would imagine that my leaf cages lose a little more as the tops of the needle palms are 30" to the top,still I would guess my needle palms are safe down to -20F(outside temp)hopefully we won't see those kind of temps but anytime we have snow cover like we...

hardyjim

Yea, :lol: or to the plants! I looked at the palms again today by the plastic that pulled down and they are looking good! I 'm glad I kept an eye on them or they would have had a rough go.I think the problem is taken care of now so hopefully thats the last time for that issue,however yesterday some ...

Had a close call Sunday night......On thursday I planted a new C.humilis in the large G/house,I was planning on keeping it from getting to cold right away along with the new cactus that were planted last week and last weekend,so sunday night we had our first really cold arctic front,winds gusting ov...

hardyjim

Looks like they are going to be o.k.maybe it was a brief exposure which is quite different then a prolonged event. I planted my C.humilis in the larger g/house a few days ago and was planing on keeping the temp above 20F for a while,well,sunday the high was 59F and last night it got down to 5F(never...

Thanks Kent,I have learned alot from reading everybody elses post as well as yours,its amazing what can be done when we all put are heads together.It will be interesting to see what your minimum temps are outside and inside(protection) and I agree about keeping moisture off plants,I think if we can ...

hardyjim

I pretty much order everything off e-bay,you can find some great deals.Needle palms are the most cold hardy,some of the sabals are pretty bomb proof too. I like Collector palms and Palms wholesale,they are not the cheapest but always send qaulity. I think mail order natives had 7g needle palms for $...

hardyjim

Definitely a good sign that spear and newest leaf are vital,yea,don't cut any fronds off until they start to turn yellow.If you see any movement out of that spear your in buisness,keep it as warm as you can,hopefully those other leaves will open up but it may be that your palm has cut its loses.If t...

hardyjim

Gary,when you transplant a palm in cold weather(or warm weather for that matter)the roots get damaged,if you then expose it to cold weather and the roots get cold they(the roots) will begin to get mushy and this opens the door to infection,the only chance this palm has is to keep the roots warm,whic...

hardyjim

I can'y think of any blue colored plants that don't handle heat well,this is a feature( the blue coloration) in many cactus too

hardyjim

Thanks DZ,the imbricata seems to be hanging in there too!

hardyjim

I have read(palms won't grow here etc)that to,I have also heard that they usuallyy don't survive below middle teens but I think people sometimes are not aware that there is a big difference between a palm stressed in drought mode(so basically dry) going into cold weather and one that is wet,this is ...

hardyjim

I would really like to see the Mazari make it,I have tried so many of these,as with most plants be tried in colder zones getting one that is a little older is the best bet,this palm is very well rooted and I think some of its color loss from earlier this season is from cold and miosture together.The...

hardyjim

Hey oppalm,I am very happy that you are doing this! I really wanted to put a thermometer in with my(leaf cages) needle palms but I needed to do it before I could get a thermometer.I will be very curious to see how warm it stays under there,I think the ground will stay closer to 40F(at least) actuall...

hardyjim

Ha,"real winter weather" has arrived here! Last winter the lowest soil temp was 40-41F under protective mulch,there is about 3" of (mulch)gravel in the cactus garden,so I don't imagine it would get much less than that .My plan now rather than taking these to single digits, is to not l...

New havardiana and parryi arrived today,here are some pics- <a href="http://s297.photobucket.com/albums/mm220/orbea641/?action=view&current=12-6-08011.jpg" target="_blank"><img src="http://i297.photobucket.com/albums/mm220/orbea641/12-6-08011.jpg" border="0&quo...

Funny you should mention a chair,I guess great minds think alike :wink: Here are some more pics of the rest of the mini g/h's and some inside pics of the larger g/h.I have not had much of a chance to use the chair in the past month but after this week I should be able to enjoy it more often!The pic ...

hardyjim

I had it on for about an hour today,(not while sun was up )the outside temp was 20F and inside it was 50F,it does have some ice and snow on it and that does help to insulate it,however if I turn it on the ice/snow will melt and it will loose some insulation but it was only on for an hour and if I ca...

hardyjim

Here is a pic I took of the west side of the yard at night,I used 8 strands of C-9 lights,I also put 4 lights a piece in the strofoam covers,this adds about 40F+ to the inside temp,I hope the mini g/h's are as warm as they are bright 8) <a href="http://s297.photobucket.com/albums/mm220/orbea641...

hardyjim

Yea, in all the researce I have done on these I have not seen any parryi babies that look like the ones I have,so they are probably something else.I have found some good deals on havardiana and parryi,also a blue form of parryi so I will be replacing the damamged ones with these and digging the dama...

hardyjim

Thanks for sharing,it will be interesting to see what else turns up in there

hardyjim

I will keep a rain shelter over mine if and when I buy one,which I am sure I will! I will buy a larger plant with a foot of trunk as I am realizing that larger plants(protected the first few years at least)are more cold hardy.

hardyjim

Hey D-Z,after going back and looking these up on e-bay,I agree with your original observation,as far as them possibly being some form of americana.I looked at a lot of different varieties of parryi and even when they are young they look like,surprisingly enough,parryi,however these would look a lot ...

hardyjim

To bad its easier to repot your palms than to mail one,I sure would have loved to get one of these.

hardyjim

The one in the first pic is blue "tequila" agave,2nd Parryi(the one with 2 plants) the third was a freebie thrown in on another order,this agave and another small one similar to it have more thorns than my americana(not pictured)-soil moisture is the problem,my other small agave that is no...

hardyjim

Yep,I think in your area all you would need is a mini g/h type set up.In Iowa you may be able some years to go with this set up, if we are talking the most cold hardy of the cold hardy;sabals,trachycarpus,needle palms,etc but heat would need to be provided some years as we almost always(always as fa...

hardyjim

Yea,I do keep records of it all but there are a lot of variables as seen this year in the agaves,I have one that is very small planted in front of the Y.aloifolia,probably same kind as at least one of the other damaged agaves,anyway it was not well rooted thus,a little starved for moisture and is to...

hardyjim

Gary,can you detail a little bit the temp and precip range of wisan and tesan during winter? I think you said tesan is by far the most cold hardy?what extremes of tempeture does tesan see during a cold winter(maximum lows)

hardyjim

Last year I left my Sago out through most of Nov,it was unfazed by 20F weather and some days not much above freezing,I think this is why they were mentioned(along with D.antarctica) as potenial plants for overwintering outside with leaf piles as the piles if done correctly, are not supposed to drop ...

hardyjim

No,nobody around here would sell something like this,I order just about everything off e-bay,they actually do have both of these but I will wait untill spring to order anything.I have read that tree ferns and some cycads can be overwintered with leaf cages but I will wait to see how the ones I have ...

hardyjim

I will just need to wait and see,things are drying out now that they are covered.I have a small one of these and it is fine but only because it was not well rooted and was much drier than the others,so,wet soil was the main problem,I think these will pull out of this as centers look solid,but the te...

hardyjim

Great collection Barb,I am looking to try some tree ferns next year D.antarctica and Mexican tree fern,I have read that a 3'mexican tree fern can grow 15' in a season

hardyjim

Yea,you can sure do a lot of tricks with mulch!not to mention covering plants with it in spring to prevent cold damage,I guess we did kind of cover that.

hardyjim

The 23F-90F does not seem to bother them but I can tell you it is a rare event as I usually can be home in time to open flaps,I would not want this to happen very often,I think twice a month would be the most -In ten years time,I hope I still live here to see them!I am kind of commited now,don't ya ...

hardyjim

Yea,my system is pretty easy really if it is above 25F and sunny,open flaps, if less or not sure of sun or not,better to cold then to hot, last year I think the temp went from 23F-90F the same day,not ideal but it did not seem to bother them much.I try to keep the temp range more like 40F in one day...

hardyjim

Thanks Barb,I have a Sago palm and thats about it,I like them,just don't run across them very often.My Sago put out its first set of leaves in 2 years,really amazing how fast they grow!basically three weeks to put out a new flush!spectacular :!: You asked earlier what outside temp was when temp in m...

hardyjim

Barb,love jade plants have grown them for years and finally have one that is taking on a tree form.Your jade is awesome!!! I would love to see more pics!Here are some pics of mine and the latest project,leaf pile around the needle palms that have not been covered yet and still look great after 18F,s...

hardyjim

I think the comment "palms attain hardiness with age" you could also add that hardiness increases with time in the ground as you can see the trachys that have been through winter in the ground are unfazed.You can see in the pics that there is some moisture on the agaves,this should begin t...

hardyjim

Thanks Knnn. Here are some pics of agaves and palms-First palm is nainital,partial spear pull-second is fortxwag,full spear pull and third pic is fortunei(large) and wagxfort,still growing,planted last Nov of 2007 <a href="http://s297.photobucket.com/albums/mm220/orbea641/?action=view&curre...

Sorry about that,your right PARRYI-Here are some pics of parryi and other agaves.the skinny leaved one is blue tequila agave,not sure of cold hardiness,supposedly 0F- <a href="http://s297.photobucket.com/albums/mm220/orbea641/?action=view&current=G-house11-19-08004.jpg" target="_b...
