But let’s move on to what interests us specifically, that is, the problems that can arise in this culture and what should be done to remedy them.


Swiss chard diseases

In any case, chard diseases, as we have said, are not as common as in other crops such as tomatoes, but we can take certain precautions both to prevent pests and to provide additional benefits to this culture.

One of the most important and effective methods is to support culture. To give some examples, given that Swiss chard contributes nitrogen to the soil, the ideal is to combine this crop with others that contribute phosphorus, such as flower and fruit crops, and in turn with those that provide potassium, such as tubers and roots. vegetables.

In this sense, Swiss chard can be planted with tomatoes, peppers, carrots and radishes, which will provide additional nutrients and benefit from the nitrogen contained in Swiss chard. In turn, if we plant it with onions, it will help keep some pests and diseases away. The same happens with aromatics which are a perfect repellent.

However, it is necessary to avoid plant spinachleeks or asparagus accompanied by Swiss chard.

Swiss chard pox

The Swiss chard pox It is a disease that manifests itself in spots on the leaves that reach up to 5 millimeters and cause them to rot. This disease is caused by the fungus Cercospora beticola, and it is recommended to use a natural fungicide and avoid replanting chard for at least 2 years in the affected area of ​​the garden.

Mold. It is not a disease, but rather a group of diseases that generate endoparasitic pseudofungi. Prevention is considered best, and although it is not as common in Swiss chard, it can affect this crop. That is why we leave below an effective product based on tansy flowers.
