Japanese Larch cold hardiness

[DaveV]

I recently acquired two japanese larch (bonsai stock) in wooden grow boxes. Can JL stay out all winter in Nebraska? With the new zoning, we are now zone 5b (previously 5a).

Thank you

DaveV.

They were shipped bare rooted and were put in wooden grow boxes last spring. They grew quite well this past year. This is a representative from the same stock.

Depending on your source, Larix kaempferi is hardy to either USDA zone 4 or 5. I think they would do fine in your zone with minimal winter protection like mulching the pot and keeping out of the wind and sun.

I was in 5b, now 6... I have always kept mine in the cold greenhouse, mostly because of the spring fluctuating temps. If you have a warm spell that puts the buds into motion, then have a cold snap, you could have problems. At least in the cold greenhouse, I can keep it more consistent, and if it breaks bud, then I can keep it warm enough to be ok. Repotting these and then having a cold spell can be fatal. But you can't repot these too late either, so for me giving them space in the house has solved all these issues.
Nice (wee) tree BTW.

Thanks Judy and Dave4. My question is, can Japanese Larch stay out in the cold (below zero) - tonight its suppose to be in the single digits. They are protected outside. (out of the wind and sun). I'm more concerned about the cold. Can the root balls tolerate single digits at night? Yes, they are from wee tree and very nice trees.

Thanks

DaveV.

If you have to ask, it's probably best to bring them in--a garage would be best, but a cold corner in the basement would work too for a single night. Single digits on recently-barerooted tree isn't a good thing.

agreed, better to be on the safe side. Unless a tree needs to have very cold temps to thrive, I don't think it ever hurts to give them more protection from cold temps if you have it available.

Since they are from WeeTree I can tell you that most likely they have never seen single digit temps in their lives... might as well bring em in ....

with the warm winter we have been having here I actually need to take trees out.... gets too hot in the garage .... lol weird weather... great trees... good job...


now that everyone is buying material from my sources I am finding it hard to actually get to the good material in time.....
