Yes, this is a great forum to talk about strawberries. The Container Gardening people might have more ideas about growing them in containers though.

My thoughts about overwintering your strawberries is that they need to be repotted probably once a year anyway, so I'd be tempted to move them into temporary plastic pots, buried up to the rim in the ground, for winter. Maybe someone here has experience with overwintering the strawberry pots.

Let the plants die back, then bring them in to a place that won't get cold enough for it to shatter, but will allow the plants to be dormant. An unheated garage or shed would work perfectly.

Whether such a place would exist would depend on the climate and situation.
