🌸How to store begonia tubers It’s bed time for begonias. Tubers can reused every year, but they won’t tolerate freezing temperatures. The tubers should be lifted out of soil, stems removed, given a good few days to dry and then stored in a cool, dry place for winter. We add sawdust for extra insulation and to help prevent them from drying out too much in storage. Doing this has freed up some more pots for spring bulbs to plant now! If have pots spare, fill them with bulbs like tulips, hyacinths
