Overwintering begonias - this is how pot and field begonias manage well through the winter

The Content Of The Article:

Although you can buy begonia every year for a small price, it is worthwhile to overwinter the plants. This is associated with little effort and saves money.

Begonias are very sensitive to frost

When the summer comes to an end, it is time for hibernating begonia to hibernate. Begonias can basically stay outdoors until the first frost, but then the resting phase begins. Then you have to prepare your pot and field begonias for hibernation. Bucket and chest plants always overwinter in the vessel. For outdoor begonias, on the other hand, you must dig up the tubers and store in cool and dark until the next spring.

Winterize begonias in the pot

If you keep begonias as balcony or tub plants, the plants remain in the pot over the winter. An exception is the one-year Eisbegonien, of which you must say goodbye to the summer, unfortunately. Tuber begonias, on the other hand, survive the rest period well and drive out again in the next season.

➜ Proceed as follows:

❶ Remove dead plant parts and dead leaves and then shorten the shoots to about eight to ten centimeters. The best place to spend the winter is in a cool, well ventilated place.

Beg During hibernation begonia in the pot needs very little water. The earth is allowed to dry out in between. Nevertheless, you must pour carefully every now and then.

❸ In the spring, you have to slowly get used to the sun and the warm temperatures. To do this, place the plants first on the windowsill or in the conservatory. From May, when no more frost occurs, the plants may then go outdoors.

Store tuberous begonias and bring them to drift again

For outdoor begonias, it is important to get the tubers out of the ground before the first frost. The plants are sensitive to frost.

➜ Proceed as follows:

❶ Dig out the field begonias and cut back the above-ground parts as described. The excavated plants must be allowed to dry well together with the tubers for four weeks.

❷ Now remove the excess soil, roots and dead leaves and stems and then put the tubers in a box of peat. Lightly cover the tubers and place the box in a cool cellar. Dark, good ventilation and temperatures around ten degrees are ideal conditions. The peat substrate should keep slightly moist. It must not form moisture in any case.

Die Already from January / February the tubers are allowed to leave the winter quarter. Put the tubers in pots with fresh soil. The dent, which has every tuber, must point upwards. From this dent the new shoots develop. Then cover the tubers thinly with soil and keep the substrate moderately moist. The first shoots soon form on the bright windowsill.

❹ As soon as the weather forecast is favorable and no frost threatens, your begonias can return to the open air, either as balcony plants or as bedding plants.


  • Cut back the potted plants and keep them in the pot
  • choose a bright, cool and well ventilated location
  • Excavate tuber begonias, cut back and allow to dry for four weeks
  • store in peat, preferably in a cool and dark cellar
  • Put tubers in soil in spring and wait for the new release
  • put into the open only after the frost period
