The best thing is to cover your trees in Snow. Put the trees on the gorund, make groups of the trees and wait for the snow. Snow is the best insulation ever. It protects from the freeze, it protects from dryout and it protects from the wind. The problem is, that you have to live in area with snow😆. Where there is no snow during winter(more common these years in the middle of Europe) I just simply water groups of my trees once a week, specialy when the temeratures goes below zero in celsius. The water makes icy crust and insulate roots too.
Good thing you specified zones. I'm in 4B, and wintering over started roughly two months ago already.
Haha, that's right! I'm in zone 6 and I started at the same time as you, just in case! Granted, mine was pretty simple... just making sure the roots were well insulated. All of my winter hearty guys that I leave outside are safe to zone 3 anyways and on a covered, unheated set up... cheers!
Have seen no one else give degree-by-degree advice, and sensible reassurances as well. Really has helped here.
I have stored my bonsai in an unheated space (covered porch with lots of windows) for the past 15 years in S Jersey. They have all done well, even when the temps warm slightly during the late day, esp when getting close to spring. Just moved and lost that space so I am looking into storing them outdoors in my garden (buried into soil, cover root mass/pots with burlap) then cover ground with plenty of natural insulation (leaves/mulch).
Hi Ben, sounds like a good plan - the covered porch was excellent though, you'll miss it! :)
@@bonsaiempire thanks for the reply! Yeah, the old porch was perfect for my bonsai and helped me justify growing more trees.
Do you have a basement cold cellar ?
Last year I put my red maples in an attic space that would get cold but not freeze. This year I am going to do the garage more than likely.
Thank you Master Neil! Very good information. Please expound on ground heat and other methods.
If you have a comppost pile, you can use it for warmth!
Ok, temperatures above 14F/-10C can't damage the roots, but frost has one more property - it freezes water in a pot. Moreover, the ice continues to evaporate (in case that you haven't snow), which means the substrate will dry out and the tree will die during the winter. Right? It seems to me that it would be worthwhile to reveal this problem in more detail
thanks for this information ⚘⚘⚘
Certainly interesting video, pity its coming bit too late on the end of december.
Removed my trees from pots, burried them in the soil and covered with leaves. Temperatures here goes as low as -30C sometimes. Luckily this winter seems to be quite mild so far🤞
SUPERB, timely advice! THANKS!
Great videos!
Any tips for areas that experience temperature swings of -10C to -40C?
Here in Ontario we get Winters with ice storms and thaws one day and -20C with snow the next.
With that kind of temperatures, you'd need some serious protection and likely a coldframe or an unheated greenhouse.
So I live in zone 5. Iowa with polar blasts that can last for a week or so. Not sure if a garage or window egress is better than being heeled outside. Newby in bonsai. Conifers junipers only.
Well if there are a few moments in the year with extreme drops/conditions - you can consider providing extra shelter for only those moments. Feel free to use our forum for some more advice from the community; www.bonsaiempire.com/forum
Great information. Thank you.
Thank you for this info.
Would storing rhem in my basement storage cellar work ?
Always something to chew on I always worry at this time of year and if my trees will survive and come out of dormancy in spring
Great video! I just got a juniper bonsai as Christmas gift. I am in zone 7a and I live in an apartment building. I do not have a yard or a garage so I keep my bonsai on my balcony. My balcony is wooden. How should I protect it when the temperature drops below 28 F? Thank you in advance!
Is it warm enough to keep your bonsai in an unheated greeenhouse at -10 celsius without covering the pot with blankets ? How about watering the bonsai in winter, is that recommended ?
I put my trees in ma's green house. One night it got 7 below zero and during the day it was a whopping 125 degrees in there! I was shocked but they seem to doing alright..
Oeh yeah, you have to be very very careful with sunlight heating a closed greenhouse!
@@bonsaiempire Thanks, it's about mid winter. I guess I'll move them to a cold room and hope they come back. The one Cherry Tree was so vigorous I was astonished...thanks for responding..
Nice, i like thanks for sharing master.
Juniper chinensis is rated to zon 4a. Is it really essential to protect it at -2°C? Or even -5°C? I have my olive trees outside at -8°C and they are fine. Shouldnt since Junipers and other like pines or spruces are much more cold resistent have no problem with those temps? A lot of tropical palms and trees could survive -2°C for a short time
Junipers can definitely take those temperatures without any coldframe or greenhouse - I'd place them on the ground though. Some more info: www.bonsaiempire.com/basics/bonsai-care/overwintering
wowww nice bonsai👍 indonesia present🙏
I was given a small Gardenia bonsai this year and its done very well through the summer, but now its getting down to the low 30's and high 20's, at night. I have a cold frame that I keep my Tridents and other trees in over winter, but Gardenias are tropical. It really doesnt like being indoors and looks rather weak. Some have said they leave them in a coldframe. Any body have any insight?
Ryan
so would you use continue using that same method all the way down to below 0? The temperature where I live gets down to about -7 - 0 in the dead of winter at nights.
The video uses Fahrenheit, not Celcius btw
@@arnie0199 I know... It's cold where I live.
@@yitcon2704 -7 F? That is cold!
ugh that yatsubusa elm @2:35 is probably one of my most favorite trees ever. what a fucking monster A+++
zone 6 to 9? Does that even count as winter?
Super
My question is does this apply to ficus as well? We experience 40 degree nights here. Thanks for the info!
Ficus is a (sub)tropical plant, for more info check: www.bonsaiempire.com/tree-species/ficus
@@bonsaiempire only issue is I keep my trees out door all year long. So I’m wondering if there are measures I can take for those colder nights.
Hey David. The link I send you is a page about the Ficus, where we mention it can be kept outside as long as temperatures are above 60°F (15°C). So with 40 degrees you will need a greenhouse - or keep it indoors.
@@bonsaiempire @David Arden I usually bring my Ficus in at around 10C to 15C here in Ontario which is a task because of the size I allowed it to get to. 😄 A couple years ago I waited a little longer (around 5C) and it was fine. My wife made sure I was on time this year LOL.
How about -45 for 6 months? I’m in northern Manitoba
OK I should’ve watched the video first. I’ll bring it inside for the winter we get long, cold winters here.
Depends on the tree species - but you'll need some serious protection
What about zone 4?
What about deciduous trees? Do they survive up to -10°C?
Wind protection and mulch around pot. I keep mine in a garage as long as the yemps ate lower then 40 IN the garage.
Thanks for using Fahrenheit.
sooooo what about -20 F cuz in the middle of the US it just be like that in the winter
You'll need a coldframe, greenhouse or garage - www.bonsaiempire.com/basics/bonsai-care/overwintering
@@bonsaiempire on a serious note I’m building a greenhouse this summer and have already been buying up nursery stock and hunting in the wilderness for bonsai material. Knowing that the plants I’ll be collecting are hardy here as long as they are in a cold frame do you see any need to keep above a specific temp in the deep winter if I’m keeping the bases somewhat mulched? Thank you for the reply 🙏
I grew up in greenhouses and am in the nursery and hard scape end of things so Ik enough to get into trouble but finding info on over wintering in cold cold is hard to find info on. UA-cam is the only introduction to bonsai I have in the middle of nowhere USA haha
I am in 3b... noone thinks about us poor bonsai people in Canada lol
I hear you. I'm in central Alberta. So minus -40c is pretty standard lol
@@allduhcheese6762 right?! Although this year has been pretty mild here in central AB
@@cherylandrews3195 ill agree with that. But we haven't hit the cold months of January and February yet
@@allduhcheese6762 wow... so mean to remind me haha, but you are so right, we have lots of cold coming :(
@@cherylandrews3195 I never anticipated the extreme cold last year and lost all 15 trees, very sad spring. Had to completely start over with all new seedling. But thats ok still learned alot 👍
Gunnison Colorado. Let em get buried by snow.
