How do I keep my outdoor begonias through the winter when it's frosty?

The begonias are in pots in the garden but the winter frosts will kill them off

How do I keep my outdoor begonias through the winter when it's frosty?
I bring my begonias inside in the fall, I have some in window boxes and some in planters and put them under my kitchen which is a crawl space that does not freeze. But first cut back the green and let the soil dry out thoroughly so they don't mold. In early spring bring them out and they will start to regrow after you give them a good drink and a little fertilizer and set them in a sunny inside location until there is no danger of frost. This way you don't even have to re-pot. If they are tuberous begonias you can also just dig up the tuber and let it dry completely before storing away in the same type location.

Reply:I'VE KEPT MINE FOR THE LAST THREE YEARS BY COVERING THEM WITH GARDEN FLEECE AND PUTTING THE POTS IN A SHELTERED SPOT. SEEMS TO WORK FOR ME.
Reply:BRING THEM IN EARLY.....LIKE LATE AUGUST........INSTEAD OF WAITING TIL L;ATE FALL....THEY WILL ADJUST......ITS USUALLY NOT WORTH THE EFFORT BECAUSE YOU CAN REPLACE THEM THE FOLLOWING YEAR WITH NEW ONES AND NOT HAVE TO TOLERATE THE MESSY CARE THROUGH THE WINTER.....
Reply:Pull the corms up, lie them right way up in trays of peat but do not cover them. Keep them in a shed or greenhouse. They will winter perfectly this way and in spring you will see new growth, just pot them and place them outdoors.

Reply:When finished flowering, take them out of the pot and let the foliage die off naturally. Then put the corm into a box of dry sharp sand, cover them with newspaper and find a dry dark place to overwinter them. Bring them out in the spring and pot them on ready for your next summer showing. Basically treat them like dahlia tubers.
Reply:Put them in the green house/garage/shed/porch - anywhere to give them shelter, that doesn't allow them to get to warm and confussed into flowering early - to prevent them dying off in the frost - not just in the winter
Reply:Bring them inside to a space where they will not freeze. Or take cuttings of them and have them rooting to put into the pots next year.
Reply:bring them into the house...its the only way to save them
