One of the common diseases of geranium plant is the appearance of white spots on its leaves. This problem can have different causes. But why do geranium leaves turn white? The first and most common reason is powdery mildew. In addition, low light also causes geranium leaves to turn white. In this article, we will discuss what causes geranium leaves to turn white and what you can do to prevent it.
The reasons for the whiteness of geranium leaves
Powdery mildew is one of the most common diseases of ornamental plants. Many nursery, flower and woody plants are sensitive. This disease is easily recognizable as a white to gray powdery growth on leaves and sometimes stems and flowers. Powdery mildew may have little effect on plant health other than detracting from the beauty of geraniums, or it may cause warping, discoloration, wilting, and premature death of infected leaves. Most powdery mildews have evolved to avoid killing their host; Because they can only survive in plant tissue.
Their symptoms and severity depend on the variety or species of the host plant, powdery mildew species, environmental conditions and the age of the plant tissue at the time of infection. Apples, geraniums, cucumbers and zucchini are generally damaged by it.
Although powdery mildew causes little damage, it can cause geranium leaves to turn white. Powdery mildew can be treated with chemical fungicides; Because it mostly affects the surface of the plant. Spray edible plants with a natural and organic fungicide based on the size of your plants. Also, powdery mildew thrives in humid environments with temperatures between 60 and 80 degrees Fahrenheit; Therefore, control the humidity of the leaves.
Lack of light is one of the causes of geranium leaves turning white
One of the reasons for the white geranium leaves is undoubtedly the lack of light. Low-light plants have long, leggy growth and fragile stems. Leaves such as geranium leaves are affected in this way. In addition, stems and leaves turn pale yellow or white. The dark colored plant turns white due to the lack of chlorophyll. Chlorophyll pigment is responsible for the green color of leaves. Chlorosis is a condition in which the amount of chlorophyll produced by the leaves is insufficient, causing geranium leaves to turn white.
To solve this problem, choose a place where your plants will receive enough light. This is the first thing you should do. Additionally, use soil that is not too alkaline in pH. A pH between 6 and 7 is good for this plant. Also, cutting the leaves should be done regularly and correctly. Pruning ensures that as much sunlight as possible penetrates all surfaces of the plant. For pruning, be sure to use quality pruning shears so that your plant is not damaged.
Pests are the causes of geranium leaf whitening
Pests can also be to blame for the white leaves on your geranium plant. Start by checking the leaves for small bugs or eggs. If found, you can remove them by hand or use an insecticide. Once you’ve gotten rid of the pests, it’s important to treat the plant with a pesticide to prevent them from returning. Various pesticides are available in the market; So be sure to read the labels carefully and choose one that is effective against your type of pest. Neem oil is an all-natural pesticide that works on a wide variety of pests and plants.
Deficiency of geranium plant nutrients
Plants need different nutrients to stay healthy, and if they are lacking in any of these nutrients, it can cause the leaves to turn white. The most common nutrient deficiency that causes white leaves is iron deficiency. To treat nutrient deficiencies, you need to fertilize your plant. Choose a fertilizer that is rich in nutrients that your geranium lacks. Be sure to follow the instructions on the fertilizer label; Because over fertilization can be just as harmful. Be careful not to get fertilizer on the leaves. Then, water the plant well and within a few weeks you will see the difference in the color of the leaves.
