Hello all,

A break from the rain, so I thought I'd have a look at my seedlings and see what needs transplanting, etc., especially since I see it's going to rain again soon, - here it is, anyway!
Ok, I purchased VITIS amurensis seed from Gardensnorth earlier this year, and thought that it was too late for cold stratification, and with any luck, might find seedlings next spring... well, the seeds surprised me and I now have at least three healthy little seedlings, yes, they are small, but the root system isn't. So, here's the thing, they are in a small pot, and I know they need to be transplanted. Should I pot them up to individual larger pots, or, considering the root system, should I put them directly in the ground. I'm wondering which would give them the best chance of over - wintering.
I know this Vitis isn't an alpine! but I'm quite new at growing shrubs and woody vines, and would appreciate any advice you could give me.

( if all else fails, I'll pot them up in larger pots and put them in a plunge bed for the winter , will also put out more seeds this fall in larger pots! )
