The following article will tell you what signs to look for and what to do about them.

Pelargonienrost

The geranium or pelargonium rust occurs very frequently in geraniums and is caused by fungi that reach the leaves with rain or rain water. You recognize this disease by brown leaves on the upper side of the leaf, while the underside is infected by brown and yellow pustules. The pelargonium rust is highly contagious, so you should separate affected plants as quickly as possible and remove affected parts of the plant.However, you can prevent the disease by protecting your geraniums from rain and always pour only on the soil, but never on the leaves.

gray mold

The gray mold (often referred to as gray mold or botrytis) is also very common in geraniums. Another common feature is that the gray pillar, like the pelargonium rust, is caused by too much moisture. Affected plants have blackish spots and / or greyish mushroom grass, especially on the leaves. Sometimes, however, the geraniums simply rot. In addition to high humidity, there are other causes for the gray mold:

As with the pelargonium grate, you can also prevent the gray stain by always pouring the geranium directly onto the substrate, but never onto the leaves and protecting the plants well from rain. A treatment is possible above all by the timely removal of infested plant parts.

Welke

Also, the wilt caused by bacteria is highly contagious and requires a separation of infested plants. This disease is mainly due to

caused - as with the two aforementioned diseases. As with these, you can also prevent bacterial wilt by using your geranium

The wilt is characterized by a wilting of affected parts of plants to their blackening and finally the death of the whole plant.

Yellow leaves on geraniums

In contrast to the diseases described above, yellow leaves on your geranium are rarely caused by fungi or bacteria, but mostly by inadequate nutrition. In other words, your geraniums suffer from a nutrient deficiency; where it is mostly the trace element iron, which lacks the plants. You can quickly remedy this deficiency with a special fertilizer.

Tips

If your geraniums want to develop little or no flowers, there is often an insufficient supply of nutrients - but not always. Often you fertilize enough, but with the wrong fertilizer. If this contains too much nitrogen, then especially the leaf growth is stimulated and flowers have no more space.
