This is how bulbous begonias can be overwintered with little care

Tuberous begonias come from the tropics of South America. As their name suggests, they form tubers as outlasting organs. Because they freeze to death from 0 degrees (32F) and die off, tuberous begonias have to hibernate frost-free. Or you keep buying new ones.

If you want to overwinter tuberous begonias or begonias, water more sparingly from the end of September so that the leaves slowly wither and the plants dry off. This pulls the energy reserves from the leaves into the tubers. If bulbous begonias bloom for too long, they lose vigor and grow weaker the following year.

Overwinter bulbous begonias in the basement to save space.

  • Take the tubers out of the ground before the first frost
  • cut backhand high
  • Check for rot or pest infestation
  • Remove infested plants or parts of plants
  • leave to rest in the dry plant substrate, sand, or newspaper
  • store dry and frost-free at about 8°C (46.5F)

Overwinter bulbous begonias in a pot or window box

If you want to overwinter your tuberous begonias in a pot or flower box, you should note the following. Cut off above-ground plant parts to about 2 cm (0.78 inches).

The most important thing during the winter dormant phase: keep tuberous begonias dry! Do not water, just moisten. Otherwise, the tubers will rot. Store the pot or planter in an airy, dark room at around 8°C (46.5F). Ventilate regularly in frost-free weather.

With or without a pot – for tuber begonias, overwintering means a vegetative resting phase with a significantly lower need for water and nutrients. If you remove the soil, you still have to make sure that it doesn’t dry out! Because they have no protective scale leaves. Therefore, moisten the tubers slightly from time to time. Don’t water!

Farewell to winter – prepare the site and plant tuberous begonias

Depending on the variety, tuberous begonias grow bushy, upright, or overhanging and are wonderful, colorful flowers, especially for shady places where hardly any plants thrive. They are therefore worth saving over the winter.

Like all begonia varieties, they prefer shady to half-shady places and well-drained humus soil. They are sensitive to drought, blazing sun, and waterlogging.

Anyone who prefers the overwintered bulbous begonias from February extends the flowering period. To do this, put the tubers in the substrate with the dent facing up and water them. Then put it in a warm, bright place in the house.

When the first leaves sprout, you can fertilize again. Put the newly grown tuberous begonias outdoors after the ice saints at the earliest. The first colorful flowers delight our senses from April.


It is worth wintering tuberous begonias. Mainly because it is simple and takes up little space. In addition, you get larger and more lush begonia plants for the balcony and garden year after year.
