Successfully overwintering begonias

The overwintering of begonia differs a little from species to species. Begonias that can also be planted outdoors like to have it a little cooler over the winter. Ice begonias ( Begonia semperflorens ), for example, are extremely happy with a bright staircase at around 16 ° C. You can also cut back the plants in autumn and overwinter in a frost-free cellar or garage with very little watering. From March, however, you should bring the pots out into the light and slowly start watering again.

The large group of tuberous begonias ( Begonia x tuberhybrida ) overwinters similar to dahlias. It forms underground tubers into which it retreats after the first frost. In autumn, cut the above-ground parts of the plant back to a few centimeters and dig out the tubers. You can now overwinter these in the dark at around 10 ° C. So that the tubers do not dry out over the winter, you should put them in a cloth bag or something similar. It is also possible to overwinter them in the almost dry earth. Watering is then not necessary and will only be necessary again when you can already see new shoots in spring. If you have overwintered the tubers, you can plant them directly in the garden after the ice saints in May. The hollow in the tuber should definitely lookup.

Only very few species of begonia can be overwintered outside, and only to a limited extent. In order for them to actually sprout again in the following spring, they need thick frost protection made of brushwood, leaves, or mulch. Even then, overwintering is not guaranteed. Especially in regions with a harsh climate and low winter temperatures, so-called hardy begonias should also be brought into the house after the first light frost.

Hibernate begonias indoors

The heat-loving elatior begonias ( Begonia x hiemalis ) are often kept as indoor plants all year round and for this reason, do not have to be overwintered. The same applies to other pure room begonias such as the trout begonia ( Begonia maculata ) or the eyelash begonia ( Begonia bowerae ).

Both species come from mountainous regions in Asia but are only partially hardy. You can find out more about hardy begonias here in our special article on the subject.
