Moving blackberry rootings in winter

I have a blackberry that is running amok. I lost control of the garden this year, and a bunch of the canes contacted dirt and put out roots. Not anyplace good. I want to dig them, pot them, cut them loose, and leave them outside (the weather is going to be back to winter in two days.)  

Will they survive? I hate to leave them till spring, I guess I will if I have to, but they are REALLY in bad places. They will take a lot of damage and be in the way before it's warm enough to definitely move them safely.

And as far as all this goes, I know blackberries root from cuttings. If I DO pot up the rooted ones, should I make a bunch of 12 inch cuts on those same canes and put them in pots too? I DID buy this plant to propagate off of. And it really is amok. It has immobilized a big rowdy wind spinner, that had to have taken it some serious effort!

There is NO space in the house for more plants. That's not an option at all.

I guess I don't HAVE to cut them loose if I dig them and pot them, could hold them till spring that way, if it would be better. Just need them not where they are growing. Can just move the whole cane and let it end in a pot.

Zone 6, we get snow and ice and below freezing temperatures and high north winds. And all of this is on the north side of the house. I could move the pots to the south side, but that's where the snow piles up deep.


Any advice appreciated!!
:D

If you want a pile of babies to relocate in spring, or give away, I would leave them attached to mom, dig the little roots up as carefully as possible, put them in pots, dig holes that will hold the whole pot, and have them in the ground where you can easily pull the pot up in the spring.

Without seeing them, I can't be sure in your cold climate if the root balls will have enough strength in the spring to put out shoots. I wouldn't lift the pots until I see a few inches of sprout at least. I suspect even 3 true leaves will be enough to cut them from mom, so long as they get a bit of babying during drought periods.

Someone re-worked "STUN" to be STRATEGIC total utter neglect. Dead plants don't get a chance to develop toughness. There are plants in nature that get a certain amount of protection their first year or two, such as strawberry runners, trees that *need* shade while young, etc.

It's a good time to transplant stuff because the water requirement is low.  That said, blackberries don't do great in pots long term.

Is it out of the question to transplant the rooted layered plants into the ground? That would be fine this time of year

Into a pot you have to worry if it's hardy enough for the cold.  My guess is yes it is but you won't know till you try.  Snow won't hurt them because it insulates them from the real cold and photosynthesis isnt really happening anyway this time of year.

If you're set on pots, protect them a little and you'll be fine. As Jay said, bury the pot in the ground.  Pots buried in the ground stay as warm as the ground.

If the roots are small you'll need to prune the top to match

I wouldn't recommend trying to root cuttings this time of year, but it does work for grapes and figs, but i would guess the wood is too old to want to root.  It might work, i don't know

You can definitely transplant though
