Do I have to dig begonia up every fall and replant every spring?
I live in Maine, Zone 4. I received the Begonia tubers to plant in the garden after the snow is gone. Do I have to dig them up every fall and replant every spring? I would like to mulch them well and leave them in the ground until spring, since I don't have a place to store them. The ground does freeze here, but I planted an Easter lily here 2 years ago and it returns every year some with new growth. When I looked them up in my Simon and Schuster'S planting guide book, it said it was hardy in zone 5. I would appreciate any information on tuberous bulbs and replanting or not.The tuberous Begonias were good for zone 3.
