Is the location right?
For example, geraniums often do not bloom or bloom only a little because they are too shady. The plants need full sun - the more, the better. If you can rule out other reasons, an unsuitable location is often to blame for the missing flowers. By the way, suitable protection against continuous rain is also part of the right planting location - in persistent rainy weather, leaves and flowers suffer and ultimately look ugly.

Don't water geraniums too often
In general, too much moisture is fatal for geraniums. The plants should be slightly damp, but in no case wet - waterlogging is poorly tolerated by the desert plants. Water your geraniums regularly, but only directly on the ground. Leaves and flowers should not be wetted if possible. Let the substrate dry well in between (finger test!) And only then water again - geraniums tolerate short periods of drought very well. If the humidity is too high or even waterlogged, geraniums often let the buds dry out and fall off.
Dampness causes many diseases
Too much moisture, regardless of whether it is caused by frequent watering or rain, quickly leads to various diseases in geraniums, induced by fungi or bacteria. Pelargonium rust, gray rot or wilt are common - with all infections, ultimately the only thing that helps is to cut off infected parts of the plant as quickly as possible and, if necessary, to separate the plant.
Don't forget to fertilize - but do it right!
Another common cause of geraniums failing to flower is incorrect fertilization. Geraniums are heavy consumers and therefore have to be regularly supplied with a special fertilizer for flowering plants. You do not necessarily have to use expensive geranium fertilizers, cheaper flowering plant fertilizers or correctly dosed blue grain also serve this purpose. It is only important that the fertilizer does not contain too much nitrogen, because this only stimulates leaf growth. However, flowering plants mainly need phosphorus, potash and magnesium.
Tips
If you cannot determine any specific causes for the lack of flowering, check the geraniums again very carefully for pests such as aphids or thrips. These leaf sap suckers rob the plant of strength, which it can then no longer invest in flowering.
