  • secateurs
  • paint brush
  • Fruit crates (small) or similar containers: Amount depends on the number of tubers to be overwintered
  • newsprint
  • fresh substrate for overwintering: dry, poor in nutrients
  • Flower pots for the begonias: the cleaned ones from the previous year are ideal for this
  • fresh substrate for pre-growing: corresponding to the requirements of tuber begonias

Cellars or unheated rooms that do not fluctuate in temperature are best for this. It should also be possible to ventilate when it is frost-free outside. the basement, cellar is particularly well suited because the temperature does not change much there and the tubers can rest undisturbed.

2. Before the first frost, start thoroughly with the upper parts of the tuber begonias secateurs to remove. This is done in the same way with every strain, whether it's hanging or upright. Now shorten this back to about two centimeters above the ground.

3. Check that out plant pulp the stalk. If this looks fresh, you can use the tuber. If even one of the stalks is rotten or dried up, the entire tuber must be discarded. Be particularly careful with this step, because the rotten tubers in particular continue to rot over the winter and can even infect the other tubers.

4. Now solve the as carefully as possible tubers from the earth. The shoot attachments could break off at this step, so extra care must be taken to avoid this happening. These are important for the flowers so that they can develop new shoots in the next year.

If you're lucky, the substrate will be dry, making this step easier. Before the next step, you need to check the tubers for pest or mold infestations and discard any that are affected.

6. put a fruit box with newspaper and fill in the fresh soil there. The bulbous begonias are now placed in the ground with the shoots upwards and, if necessary, provided with signs that indicate the variety or color.

7. Now transport the tubers into the for this designated space, while the blooming beauties can enjoy their well-deserved winter rest.

8. Pour during hibernation No way. Regularly moisten the tubers slightly with a spray bottle so that they do not dry out completely and can be brought forward immediately after overwintering.

9. Finally, dispose of them plant parts and tubers on the compost. Infested tubers, on the other hand, in household waste.

Tip: Avoid using gloves to avoid injuring the extremely delicate tubers. If you must use gloves, you should use gloves that are as thin as possible.

Propulsion Guide

Driving tuberous begonias: instructions

The propulsion or Prefer after hibernation ensures that the bulbous begonias bloom for a longer period of time. The best time to bring them forward is from February, as there is already enough light available from this month.

The propulsion succeeds as follows:

1. Prepare individual pots or a planter for the tubers. The substrate should meet the requirements of the plants and in any case be fresh.

2. Now take it carefully tubers individually from the cellar and place them in the fresh substrate with the dent facing up. Moisten them sufficiently and place the pots in a warm and bright place. Here you can help with plant lights when the sun only shows itself sparingly.
