Your grape
plants will probably survive the winter in the pots provided they are large enough and are well protected for the winter. Pile up the snow over the pots. This will help to insulate the roots. The
plants should be in a well protected area out of the open spaces and protected from the wind. Keep the pots well covered into
spring to help reduce the danger of repeated freezing and thawing on the roots.
plant them once the ground has warmed and new growth is seen on the vines.
Good luck
