Celtis sinensis - chinese hackberry questions

[defra]

Hi there nutters!
Coming week i will pick up a nice tapered celtis sinensis stump
nebari 22 cm (8,6 inch)
Height 30 cm (11 inch)

But heres the thing
I am gathering info on the species since i dont know much about them and some info confuses me regarding the hardines.

Main thing i like to know is how cold hardy is the sinensis cultivar?
im in the netherlands zone 8b and i like to know what action i have to take regarding the winter protection

Does anyone has good links with info on this species ?

Defra,

it grows down here and no need for refrigeration.
Takes a rest and then awakens.

Does that means i should keep it indoors over the winter?

How long does it need to go into dormancy(rest)?

Ive read that they need protection from -5°c it sometimes gets alittle colder here

 

[Anthony]

Defra,

dormancy on our side might be induced by shorter days.
Then our lowest low is 18 deg.C at night for about 12 hours.

So I guess, for a tropical - the lowest safe low is 13 deg.C

You should be able to go safely to 13 deg,c.

Also check the zone map for China.

Do cuttings when you can, makes you less anxious. Also allows you
to test outdoor conditions.

* Can you not ask the person you bought it from ?

I will ask the person im buying it from but id like to know a few things before i buy something also ulmus parvifolia is able to adept to our climate and even drops leaves in fall so i wonder if its the same with this species

 

[Anthony]

Hee hee Defra,

Ulmus parvifolia from South China, does the same in our climate, and they have been here since 1980.
Seems as though they need short daylight for dormancy.
We have had many, many successful rooted cuttings.

Above 32 in the cold greenhouse.

Maybe @Dorian Fourie .

Just keep it how it been kept.

Above 32 in the cold greenhouse.

This^
Sometimes it gets below 32 in there, but not for any long period of time, and roots generally don't freeze solid as the heat mats keep the pots from freezing.

I have one in the unheated shed. It will experience some nights in the 25F area but never more then two in a row(rare in there). During the coldest days it sometimes goes down to 30F in there but again never for extended days. No heat mats in there, I just water when it is not frozen and drying up a bit. They are one of the first plants here to drop leaf in early Fall.

Thnx all!
So i think be keeping it in my shed too i am going to install a electrical heater with the thermostat around 0°c to max 5°c
Depending on how the seller threated it!
Ill pick it up on tuesday ill post a thread when i get it home to show it

Indoors isnt realy an option i think with our central heating system and my wife always saying its cold lol

 

[JudyB]

You'll have to show us when you get it, the species is one of my favorites. I just posted some leafless photos of my two.

Hi Defra

My chinese hackberry has survived a few nights when the temp dropped to -3 celcius. I think the one thing you need to be careful for is the temperature drop if there are developing buds on the new branches. Also here is South Africa we do get frost so if that is a possibility for you, look at getting some frost netting.

If you keep it in your shed, it should be fine as it will be out of the wind and severe cold.

All the ones I've had which are outdoors have died, except for one which is in a garden bed.

Did you give them any protection in winter ?

 

[dirk hoorelbeke]

Stay away from what is not totally hardy. Don't know how strong celtis is.

 

[jeremy_norbury]

On occasions, not and that's when they died. 2 years ago there was a very cold patch very late in early spring and it killed ALL of them.

The seller kept it outside untill -5 only then inside the shed so ill be trying to keep it outside as long as posible but id rather be safe then sorry by keeping it frost free tough

Thnx for all the info provided here
Will post up a thread soon!

 

[dirk hoorelbeke]

If the seller can keep it outside with -5 it must work for you too.
