In this blog post, I’m going to tell you why cucumbers turn white and how you can stop it happening.

Cucumber Leaves Turning White

Cucumbers are easy to grow from seed. Seeds germinate quickly and produce plants within 2 weeks. Once the cucumber plant reaches maturity, it produces fruit. Fruit production depends on the weather conditions during the growing season. In warm climates, cucumbers tend to mature early and produce more fruits. In cooler climates, cucumbers tend not to mature until later in the summer and produce fewer fruits.

Powdery Mildew

Powdery mildew is caused by fungi fungus that attack the leaves of the plant. It appears as white powdery spots on the leaf surface. This disease is common in cool, moist areas such as greenhouses, nurseries, and gardens. Powdery mildew is spread by airborne spores produced by the fungus. These spores float in the air and land on the leaves of the host plant. The spores infect the leaves and begin to grow into mycelium. Mycelium grows along the veins of the leaf and spreads rapidly. As the mycelium continues to grow, it covers the leaf surface and blocks the normal photosynthesis process. Eventually, the leaves turn yellow and die.

Get Rid of Powdery Mildew

Powdery mildew is a fungal disease that affects many plants. It is caused by fungi called powdery mildews. These fungi infect leaves, stems, flowers, fruits, and seeds. Powdery mildew is very common in humid areas such as greenhouses and nurseries. It is also found outdoors in warm climates during wet seasons. This fungus spreads easily from plant to plant. It grows on the surface of the leaf and produces white spots or patches. Leaves become yellowish and distorted. In severe cases, the whole plant becomes infected.

Using Fungicides

Fungicide sprays are available for controlling powdery mildew. They usually contain copper compounds, sulfur, or other chemicals. Spraying fungicides is not recommended if the weather conditions are dry because the spray does not penetrate well into the soil. Instead, apply fungicides only after the weather turns rainy.

Baking Soda

Baking soda is a natural product that contains sodium bicarbonate. It is used to clean dishes and remove odors from the air. Baking soda is also used to neutralize acids. It is effective against bacteria, mold, and yeast. Baking soda is safe to use around children and pets. Citric Acid


Citric acid is a souring agent that is found naturally in citrus fruits. It is used to preserve foods and give them a tart flavor. It is also used to prevent spoilage of meat and fish. Citric acid is used to make pickles, jams, jellies, marmalades, and sauces. It is also used as a preservative in many processed foods. Sodium Benzoate


Sodium benzoate is a chemical compound that is used as a preservative. It is added to milk products to prevent mold growth. Sodium benzoate is also used in soft drinks and other beverages to prevent the growth of bacteria.

Excessive Moisture

Moisture is the enemy of any product. In the case of milk, excessive moisture leads to spoilage. This is because milk contains protein and fat which are prone to bacterial growth. Bacteria thrive in moist environments. To avoid this problem, manufacturers add sodium benzoate to milk to inhibit the growth of bacteria. However, if the level of sodium benzoate exceeds 0.1%, the flavor of the milk becomes bitter. Therefore, the maximum concentration of sodium benzoate allowed in milk is 0.15%.
