Begonias are the ideal houseplants: they bloom even in winter - if not to say, all year round - and require little light. We have summarized here which types are particularly well suited for the home and how best to go about planting, maintaining and propagating.

There are more than 1, 000 different species and varieties of the begonias, some of which have been bred specifically for in-house culture. If you want to keep begonias as houseplants, you should make the right plant selection. Particularly recommended are the so-called Elatior begonias, which are not colloquially called "room begonias" for nothing.

Begonias for the home

The houseplants among the begonias are at least as colorful and versatile as their colleagues in the garden or on the balcony. They reach heights of between 20 and 40 centimeters, have simple or double flowers and a color spectrum that covers almost all rainbow colors. In terms of growth, they are sometimes bushy, sometimes upright, sometimes hanging and can therefore be planted both in the pot and in the hanging basket. In addition to the florets, it is worth taking a closer look at the leaves of the begonia. Botanists assign the begonia to the family of the slant family and the name actually says it all: their leaves are divided into two different halves by a central rib - so clearly crooked.

Begonia: winter flowering houseplant?

The begonia is considered the winter flowering houseplant par excellence. However, this reputation does not live up to it: if properly cared for, indoor begonias bloom for almost a whole year. After flowering, they have to be disposed of because the plants are so exhausted during their extensive and abundant flowering that further cultivation is no longer useful.

Begonias for dark locations

Begonias are houseplants that get by with little light and are therefore ideally suited to beautify the somewhat darker corners in the house. In addition, they make no particular demands on the air humidity or the ambient temperature: they thrive at a normal room temperature.

Which soil do begonias need?

Apart from the right care, the lifespan of begonias that are kept as houseplants depends heavily on the substrate. You can plant your begonias in conventional potting soil, but you should definitely rely on quality soil from specialist dealers. It is fresh, loose and rich in humus and nutrients to provide the plants with a good foundation during their long flowering period. In order not to let jamming moisture appear in the bottom of the pot, it is advisable to fill in a layer of expanded clay or gravel.

Proper watering and fertilizing for a long flowering period

Indoor begonias are very thirsty, which is why the substrate should always be slightly damp. Waterlogging or too wet earth, however, let their roots rot. It is better to check from time to time whether water has collected in the pot and your begonia is in the wet. When watering, it has proven useful to use room-warm and low-lime water for the begonias. Begonias are fertilized all the time, preferably every two weeks with a liquid flower fertilizer. The long flowering period can only be guaranteed with an adequate and regular supply of nutrients.

Begonia care

The effort that one has with begonias as houseplants is limited, especially since the plants can only be cultivated for one season anyway. In addition to watering and fertilizing, it is very beneficial for the flowering and health of begonias if you cut off withered and dead plant parts such as stems and leaves. This prevents fungal diseases for which the begonia is unfortunately susceptible. Aphids can also occur very rarely.

Gardener's tip: Begonias are potted plants, but often the size of the pot is not enough. Therefore, plant your begonia in a new pot after purchase. As a rule, the houseplants are sold in pots that are much too small, and the soil is usually not high enough to serve the begonias as a permanent home.

Fortunately, the short life span of the begonias in the house can be counteracted simply by increasing the plants themselves - this also saves you from having to buy new begonias every year. To do this, cut off shoot tips (head cuttings) or leaves (leaf cuttings) in April or May and put them in special potting soil or potting soil that has been mixed with a lot of sand. Keep the substrate permanently moist and cover everything with a film or transparent hood: this increases the humidity. The only tricky thing about propagating begonias is that the cuttings need a relatively high level of soil heat in order to develop their own roots. The recommended 20 degrees Celsius is best achieved with a heated propagation bed or by placing a floor heating mat.

Alternative: leafy leaf begonias

Leaf begonias are a great alternative to flowering begonias. The so-called Begonia Rex hybrids were also bred specifically as houseplants and are by no means "only" green plants for the home. They impress with wonderful foliage in different shapes and colors, from silvery green to red to deep violet. The top of the leaves are additionally patterned and present themselves with striking marbling, dots, speckles or stripes. The culture and care is the same as that of Elatior begonias.
