When the leaves of parsley turn yellow, gardeners refer to it as parsley disease. This is an umbrella term that includes several diseases.
Symptoms not always clearly assignable
The parsley in the garden or in the pot on the balcony cares, does not grow properly, gets yellow leaves and finally dies.
These disease patterns are experienced very often by amateur gardeners. Not always the cause can be clearly identified. However, you can safely assume that a poor location and improper care promote diseases of all kinds.
If the parsley stands in a place where it feels comfortable, diseases almost never occur.
Rotting roots and leaves
Nematodes, maggots and fungi cause parsley to rot. But this can be clarified only by examining the soil. Most often, anyway, incorrect watering is responsible for the death.
To prevent the occurrence of rotting diseases, choose a good location for parsley. It should not be grown on beds where other umbelliferous plants have stood in the last three years.
The soil must be quite loose, so that rainwater and irrigation water does not accumulate. Watering you need to be very careful. Any too little or too much can promote rotting of the plant.
Powdery mildew on parsley
Powdery mildew is caused by a fungus whose spores settle on the leaves, causing a grayish coating.
The cause is usually that the parsley is too dense, providing ideal conditions for the fungus to spread.
Powdery mildew is particularly severe when the leaves are permanently damp. Therefore, water the parsley exclusively from below.
