Although you can buy begonias every year for a small price, it is worth hibernating the plants. This involves little effort and saves money.Begonias are very sensitive to frost. When summer comes to an end, it is time for hibernating flowering begonias to hibernate. Begonias can generally remain outdoors until the first frost, but then the rest phase begins. Then you have to prepare your pot and field begonias for hibernation. Container and box plants always overwinter in the container. In the case of field begonias, on the other hand, you have to dig out the tubers and store them cool and dark until the next spring.
Hibernate begonias in a pot
If you keep begonias as balcony or container plants, the plants stay in the pot throughout the winter. An exception is the annual ice begonia, which you unfortunately have to say goodbye to after the summer. Bulbous begonias, on the other hand, survive the rest period well and sprout 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, begonias need very little water in a pot. So the earth can dry out in between. Still, you need to water gently every now and then.
❸ In spring you have to slowly get used to the sun and warm temperatures again. First place the plants on the windowsill or in the winter garden. From May, when there is no more frost, the plants are allowed to go outdoors.
Store bulbous begonias and bring them out again
For outdoor begonias, it is important that you get the bulbs out of the soil before the first frost. The plants are very sensitive to frost.
➜ Proceed as follows:
❶ Dig out the field begonias and cut back the aerial parts as described. You must then let the excavated plants and the tubers dry well for four weeks.
❷ Now remove the excess soil, roots and dead leaves and stems and then the tubers come in a box with peat. Cover the tubers lightly and best place the crate in a cool basement. Darkness, good ventilation and temperatures around ten degrees are ideal conditions. You should keep the peat substrate slightly moist. Under no circumstances should moisture form.
❸ The tubers may already leave the winter quarters from January / February. To do this, place the tubers in pots with fresh soil. The dent that each tuber shows must point upwards. The new shoots then develop from this dent. Then thinly cover the tubers with soil and keep the substrate moderately moist. The first shoots will soon form on the bright window sill.
❹ As soon as the weather forecast is favorable and there is no longer any risk of frost, your begonias can go outside again, either as balcony plants or as bedding plants.
