What are geraniums good for?

Our tip: geraniums as house plants

If you don't own a balcony or terrace, you don't necessarily have to do without colorful geraniums - because some varieties can also be grown as indoor plants. You can find out here which varieties are particularly suitable as indoor plants and how you can best care for your "indoor geraniums".

Geraniums, which botanically correct are actually called pelargoniums (Pelargonium), come from the cranesbill family (Geraniaceae) and were originally only native to South Africa, especially in the area around Cape Town. In the meantime, however, they have started a worldwide triumph and are rarely missing on a balcony or terrace in summer. What very few people know: Geraniums can also be grown on the windowsill.

Noble geraniums (Pelargonium x grandiflorum) are particularly suitable as indoor plants. This is not surprising, as they were originally grown as indoor plants. The upright and compact growing geranium hybrids have particularly attractive and large flowers in many different colors. Leaves with a serrated edge are typical of noble geraniums.

Butterfly geraniums or fragrant geraniums are also very attractive indoor plants - they also give off a pleasant scent. The variety ranges from ‘Chocolate Peppermint’ (chocolate mint aroma) to ‘Purple Unique’ (wine gum aroma): There is a suitable geranium for every taste.

Hanging geraniums (Pelargonium peltatum) are best shown to their best advantage in a hanging basket, even when grown in rooms. However, they become very large and require sufficient space in the house.

Proper care of "room geraniums"

The good news first: Both indoors and outdoors, geraniums are absolutely easy to care for. However, good drainage in the pot or planter is essential for indoor culture. Because geraniums are very thirsty and need plenty of water - but do not tolerate waterlogging at all. You can easily avoid this by adding a layer of stones or expanded clay to the bottom of the pot. You can also mix the substrate with a little sand. The earth itself should be rich in nutrients and humus. If it has already been fertilized, you do not need to start fertilizing your geraniums until after about three to four weeks, but then at regular intervals. So you can enjoy the colorful flowers all summer long.

When choosing the right planter, it is best to play it safe right away and choose a pot size larger. Geraniums need space to develop. Also keep in mind that upright cultivars can grow up to 40 centimeters high and hanging geraniums develop stems that are more than 150 centimeters long. This must be taken into account when choosing a location. In addition, geraniums also prefer a sunny to partially shaded place in indoor cultivation. The more light they get, the more flowers they show. If you also clean the flowers regularly, the flower formation stimulates further top performance.

But be careful: geraniums are poisonous! Although completely harmless to humans, geraniums represent a source of danger for pets such as guinea pigs or hamsters. They should therefore be placed out of the reach of animals.
