Provide geraniums with liquid fertilizer
Geraniums, as the pelargoniums should be called at this point for the sake of simplicity, are real heavy eaters and therefore regularly need good “feed” in the right proportion. The fertilizers used should focus more on magnesium and potash than on nitrogen - a lot of nitrogen stimulates leaf growth, but not flowering. For this reason, specially formulated liquid fertilizers for flowering plants are also ideal for geraniums - or you can use geranium fertilizers straight away.

It is better to fertilize geraniums weaker and more often
When fertilizing geraniums, the rule of thumb is that it is better to fertilize the plants more often - and in a weaker concentration - than less often (and then immediately in higher doses). The more frequent fertilization supplies the plant with nutrients and at the same time prevents the sensitive roots from being burned by fertilizers that are too strong (because they are corrosive).
Insider tip for geraniums: fertilize with blue grain
Blue corn is a real insider tip for geraniums and other flowering plants. In fact, this tried and tested fertilizer is an excellent geranium fertilizer - provided you use it correctly. Blue grain is very strong and can therefore burn the roots if overdosed and cause the plants to die off so quickly. The following dosage has proven itself:
- Dissolve a tablespoon of blue grain in 10 liters of water
- and use it to water your plants once a week.
- Don't overdo it with watering,
- but really only water as much as the plants really need.
Grandmother's home remedies: coffee grounds & Co.
But before you go to the garden market and buy fertilizer, it is better to keep the coffee grounds from your breakfast coffee - these are ideal as a natural fertilizer for geraniums and many other balcony plants. Coffee grounds contain exactly the right composition of nitrogen, potassium and phosphorus and can be administered once a week together with the irrigation water - or simply distributed like compost in the root area of the plants.
Tips
Be careful not to wet the leaves or flowers when watering and fertilizing the plants.
