Begonias - care, plants and fertilizers

Begonia - dragon wing - begonia

It blooms from May to October, provided that it grows partially shady and rich in humus soil. The begonia usually reaches a height of 20 to 40 centimeters.
Begonias grow alternately, the leaves asymmetrical.
The genus includes hundreds of hybrids and species. These have numerous, individual and attractive forms and growth types.

Begonias (Begoniasemperflorens)

The very extensive genus is divided into three groups:
  • Leaf begonias,
  • Tuberous begonias and
  • Begonia with Erdstämmchen (rhizomes).
Not only in the garden, but also in the room begonia are very popular because of their beautiful flowers.


The beautiful red, pink or white flowering begonias tolerate no frost. If, however, they were only sowed after the icy sacs, the begonias would not have enough time to grow and blossom until the summer. In a pre-culture, they are sown in the warm room on the windowsill or in the greenhouse around the end of January and planted outside in May. Previously, the small Begoniensamen had won from their capsule fruits. In this type of propagation, the very tiny seeds should be scattered only on the seedling soil. Please do not cover the seeds with soil.
Begonias can also be propagated with about 10 cm long cuttings. If you have initially removed the first lower leaf, you put it in a peat-sand mixture. Then do not keep these cuttings too moist.
Also, by sharing rhizomes, begonia is easily and reliably increased.
Tuberous begonias can be multiplied well in addition to the propagation of cuttings well over the brood nodules formed in the autumn on the leaf axils.
The brood knots are collected immediately before the death of the Begonientriebe. The tubers are stored at 12 to 14° C during the winter. In spring, put them in slightly damp soil. Please make sure that the nodules are not completely covered with earth.
Hybrids of tuberous begonia can also be propagated by dividing a tuber. Each section must have at least one vegetation point. Each piece comes in a separate cultivation pot, the soil should contain a lot of peat.
But as so often, there is an attractive alternative for individual and self-sufficient cultivation: In May, buy pre-grown plants in the nursery of your choice. So you have fast and uncomplicated healthy, small Begonia plants.

Care and fertilization

Once the begonias in their garden, in the flower box or in the pots have grown up and start to flower, begonias barely work. They then enchant with their opulent flowers.
Only the cleaning you must not forget. Withered plant parts must be cut off every few days. This encourages the plant to constantly form new buds. In addition, it can prevent diseases.
Mildew, aphids and caterpillars certainly appear everywhere in the garden. With one-year-old summer flowers such as the begonias one should, however, think about whether one should do without a costly fight and the use of chemical agents better. Caterpillars can be collected and the aphids help us against aphids. The mildew can be prevented by not planting the begonias too densely.
Please also make sure that the begonias are not constantly irrigated by the lawn sprinkler.
If the flowers remain very small and the leaves are pale, your begonias may suffer from a lack of nutrients. Then you should help them with a dose of fertilizer. First dampen the soil, then work 20 to 30 g on the square meter into the soil.
Last, but not least, weeds should be regularly weeded between the growing begonias. If the begonias are still small, this is especially important so that the still small flowers do not suffocate.

Begonia as a balcony plant

The begonia likes a half-shady location. They can tolerate full sun in spring, but only to a limited extent in summer. As a balcony plant, the begonia is therefore suitable for balconies and terraces with morning or evening sun. Direct midday sun should be avoided. This is also because begonias need a relatively large amount of water. The earth should always be slightly moist. Since the nutrient consumption is high, the soil should be fertilized with liquid fertilizer starting in April. However, care must be taken to ensure that no water gets to the plant, as this can support the fungus formation.

care instructions

The begonia grows fast and needs many nutrients for the numerous flowers. In order to enable a healthy growth, a plant distance of 20-25cm should be kept.


Sowing begonia is not the easiest. Seeds should be sowed in March and kept warm from the beginning. Unfortunately, only few of the seeds germinate. Hobby gardeners say that often less than 50% of the seeds really germinate.
The Begonia neighbors like Tagetes (marigold), Buxus and Chrysanthemums.
