Actually, parsley is a fairly robust herb that requires little care. However, parsley is also a real diva among herbs. It only thrives if you plant it in a favorable location. Then illnesses can do little to harm her.

The most common parsley diseases
- root rot
- stem rot
- parsley wilt
- mildew
When the leaves of parsley turn yellow, the gardener speaks of the parsley disease. This is an umbrella term that includes various diseases.
Symptoms cannot always be clearly assigned
The parsley in the garden or in the pot on the balcony takes care of itself, does not grow properly, develops yellow leaves and eventually dies.
Hobby gardeners experience these symptoms very often. The cause cannot always be clearly identified. However, you can be sure that a bad location and incorrect care promote diseases of all kinds.
If the parsley is in a place where it feels comfortable, diseases almost never occur.
Rotting roots and leaves
Nematodes, maggots, and fungi rot parsley. However, this can only be clarified by examining the soil. Incorrect watering is usually responsible for the death anyway.
Choose a good spot for the parsley to prevent blight from developing. It must not be grown in beds where other umbellifers have stood in the last three years.
The soil must be very loose so that rainwater and irrigation water do not accumulate. You have to pour very carefully. Any too little or too much can encourage the plant to rot.
Powdery mildew on parsley
Powdery mildew is caused by a fungus whose spores settle on the leaves and cause a greyish coating there.
The cause is usually that the parsley is too dense and thus offers ideal conditions for the spread of the fungus.
Powdery mildew is particularly severe when the leaves are permanently damp. Therefore, only water the parsley from below.
tips and tricks
If the parsley in the garden or on the balcony is affected by a disease, it usually makes sense to uproot the plant and dispose of it in the household waste. Reseeding and planting in a suitable spot are the best measures against parsley diseases.
