The hanging geraniums (Pelargonium peltatum) with their shoots up to 150 centimeters long are popular balcony flowers that show their blooms all summer long. With good care, your balcony railing becomes a real eye-catcher.
Hanging geraniums need a lot of water
How often should you water hanging geraniums?
Like all geraniums, hanging geraniums also need a lot of water - especially during the warm and dry summer months - but at the same time they cannot tolerate rain and certainly not waterlogging. Rainy weather often causes the flowers to become unsightly.
When and with what should hanging geraniums be fertilized?
Hanging geraniums are real heavy feeders, which are best supplied with a liquid flowering plant or flower fertilizer (€1.95) two to three times a week. Of course, you can also fertilize the plants with a special geranium fertilizer, but this investment of money is actually not necessary. It is best to fertilize when watering and if possible not on dry soil.
Do you have to cut hanging geraniums? If yes, when and how?
Regularly cleaning out faded shoots makes sense with many varieties to encourage the hanging geraniums to form more and more new flowers. In the meantime, however, there are also geranium varieties that are self-cleaning and do not have to be cleaned. Otherwise, hanging geraniums are cut back before hibernation, at best in September or October. A further pruning is finally carried out in early spring.
When is the best time to repot hanging geraniums?
If you overwinter your hanging geraniums, you should repot the plants in fresh substrate every spring. You can combine this measure with the pruning.
Which diseases are common in hanging geraniums?
Various fungal diseases occur in hanging geraniums, mainly caused by damp weather or incorrect care. Mildew, pelargonium rust, gray mold and wilt are the most common. These infections are often due to excessive moisture (e.g. due to damp weather or too frequent or incorrect watering).
Which pests do you have to pay particular attention to hanging geraniums?
Aphids, whiteflies and thrips in particular are often found on hanging geraniums. All pests can be fought quite well with dishwashing liquid. To do this, mix 500 milliliters of water with a few dashes of washing-up liquid and a tablespoon of vegetable oil. Dip the affected plants in the mixture or, if dipping is not possible, wipe the leaves individually.
Are hanging geraniums hardy?
Hanging geraniums are not hardy. You should put the plants in their winter quarters before the first frost and overwinter there in a frost-free, but cool place.

The highly contagious pelargonium rust occurs mainly in damp weather or when watering is incorrect. This can be prevented by installing rain protection in good time. You can also protect the flowers and leaves when watering by only watering the plants from below.
