Hi Shortie,
I've just lifted some Strawberries which were in flower and they seem fine.
This year i'm growing mine in growbags on one of those Wilko 4 tier mini greenhouses (without the cover). About 10 in each bag.
I've put funnels into the bags so I can water more easily when the foliage takes over.
According to the Ken Muir fruit book with the table top method you just lift the bags off and put somewhere out of the way over winter.
I'm going to sit mine on bricks in a corner out of the way!
