Cucumber Plant Turning Yellow, White, Brown, Black

It consists of low calories and high amounts of water. They grow quickly and beautifully but need proper care. Here are some reasons that you should know and take preventive measures to fix this issue.

Reasons for All Colors

1. Nitrogen Deficiency

The first and common reason is the over-watering of the cucumber plant, which turns its leaves yellow, white, brown, and black. When the cucumber plant leaves start to discolor then it is not a healthy sign. Over-watering damages its roots as too much water is submerged in the soil. Excess water causes the growth of molds at the sides of the roots, which damages the root part and stunts its growth. When the roots of the cucumber plants are damaged, it stops taking in nutrients, which leads to chlorosis.

Treatment

To overcome this problem you need to water the plant suitably. To fix the problem of chlorosis you need to use nitrogen fertilizer, which will properly dilute the soil and prevent root damage. Nitrogen fertilizers are used to overcome the nitrogen deficiency and treat the plant, which is turning yellow, brown, white, and black.

2. Potassium Deficiency

Potassium deficiency is another cause for the cucumber plant, which turns its color to yellow, white, brown, and black. When the nitrogen deficiency increases and leads to the inner parts of the roots then it causes potassium deficiency because at this level the plant needs more potassium to survive. Potassium plays a vital role in plant growth and its deficiency leads to stunted growth of the plant. The cucumber that grows with potassium deficiency consists of many diseases.

Treatment

Potassium fertilizer is available, which corrects the ratio of potassium that plants need. Once the potassium fertilizers fulfill the plant requirement then the cucumber plant grows normally and quickly. The soluble potassium fertilizer is penetrated into the soil so that they reach the root level and fix the potassium deficiency.

3. Magnesium Deficiency

Well, magnesium deficiency is another cause of cucumber plant discoloration (yellow, black, white. and brown). Magnesium deficiency is basically caused by excessive potassium, calcium, and ammonium. When the cucumber plant leaves turn into a yellow color it means that the plant is suffering from magnesium deficiency.

Treatment

For treating magnesium deficiency you need magnesium-rich minerals for the soil of the cucumber plant. You can also spray it on the soil, which will make the leaves greenish again and fix the magnesium deficiency. Magnesium will lead to photosynthesis and reproduction of the cucumber plant.
