Are you noticing white spots on parsley sitting in your herb garden?
Parsley is a wonderful herb to grow at home. The refreshing flavor and aroma of the plant is simply amazing. Although it is a low maintenance and non-fussy plant, sometimes it suffers from certain problems like white and light brown spots on the leaves.
In this article, we will discuss the causes and treatment of white spots on parsley leaves.
White spots on parsley
One of the most common issues with parsley is the white spots on the leaves. There can be a number of reasons behind these leaf spots including the quality of soil, blockage of sunlight, fungal and bacterial infection etc.
Below are the most common reasons behind the white spots on parsley :
1. Poor soil
The first and foremost reason behind the leaf spots in parsley is the low-quality soil. Generally, this plant required nutrient-rich and moist soil with decent drainage ability.
If the soil is dry and of poor quality then the plant will not thrive. When it is combined with high humidity, several fungal diseases start attacking the plant.
2. Lack of sunlight
This is the most common mistake people do which results in white spots on the leaves of parsley. Not just parsley but lack of sunlight can cause white spots on any plant like basil, sage, mint etc.
This is because the plant doesn’t get enough chlorophyll which is the main reason behind the green color of plants.
3. Powdery mildew
Powdery mildew is another common reason behind the white spots on parsley. It is a fungal problem which attacks the plant due to high humidity and lack of moisture.
It mainly attacks the young leaves and is followed by their curling. The infected leaves get generally covered by the white powdery mildew.
4. Bacterial diseases
White spots on parsley may also be due to bacterial problems. Certain bacteria can attach itself to the leaves in different ways. If the white spots in your plant are due to this problem then you may also notice brown and tan spots near the edge of the leaves.
These leaves become dry and weak and also can be plucked by touching. However, older leaves are more likely to be attacked by bacterial problems than the new ones.
While the bacterial diseases are a matter of concern, you can easily treat them using copper fungicide as soon as you notice the symptoms.
Apart from these problems, there are some other major diseases that may cause white spots in parsley. These are as follows :
Spots Septoria – Spots Septoria as the name suggests, is a common leaf disease. This is caused due to an infected seed and keeps affecting the leaves of parsley for long. Symptoms of this disease include small tears and red to brown margins. It can be seen more commonly during the rainy season and in excess of irrigation.
Stemphylium – Stemphylium is another recent fungal disease which has been found to be affecting parsley. It is also commonly seen in onion, garlic, leek and asparagus plants. It is seen as small spots which begin to get large as time passes and also turn dark brown. This disease generally attacks older leaves.
