Why Are My Pepper Plants Turning Yellow?

Why are my pepper plants turning yellow? You are about to find out why pepper plants turn yellow and what to do about it, so let’s begin.

Discoloration of the leaves is one of the most frequent problems with pepper cultivation. Numerous factors can cause pepper leaves to become yellow. Let’s examine some potential causes of your pepper plant’s yellow leaves.

A lack of nutrients is one common reason why pepper plants turn yellow. Nitrogen, phosphorus, and potassium are the nutrients your pepper plant needs most. Magnesium, calcium, and other trace elements are also necessary, though these issues are less frequent.

Inconsistent watering is another potential reason why pepper plants turn yellow. Your pepper plants may become stressed from over-watering, resulting in yellowing foliage, reduced growth, and decreased pepper yield.

Finally, pepper leaves may turn yellow and die due to extremely high temperatures. When the temperature drops below 50°F, this happens frequently.

How do you fix yellow pepper plants?

Here are some solutions for fixing your yellow pepper plants.

Right Soil and Watering

Think about repotting the pepper in a container. By poking holes in the soil with a garden fork or adding compost, you can loosen up compacted soil in a garden.

Pepper plant containers and the soil both need to be able to drain water. Choose a container with adequate holes, and plant your pepper plants on soil that drains effectively.

Allowing the soil to somewhat dry up before providing pepper plants with additional water is another way to prevent overwatering. When watering pepper plants, the soil surface in the container or surrounding the plant in the ground should be dry.

Prevention of Diseases

Plant diseases that damage peppers are frequently incurable. You will need to remove the sick pepper plants from your garden if they can’t be treated. Additionally, it is advised to wait a year before planting other nightshades in the same spot for fear that they may contract the same disease. 

Preventing the disease in the first place is the best strategy to control bacterial leaf spots. Try to avoid often wetting the leaves of your pepper plant. Instead of watering the leaves, concentrate on the plant’s base.

Keep Away from Pests

The ideal one would be organic and kill the pests without harming people or helpful insects. Neem oil, which suffocates bugs or interferes with their capacity to feed, is one of your possibilities. Another risk-free option is insecticidal soap, which kills insects by washing away the coating from their bodies.

Adequate nutrients

You can treat nutrient deficiencies by adding the necessary minerals to a balanced fertilizer. Alternatively, you may add Epsom salt to the soil to enhance it with magnesium and eggshells to the ground to boost calcium.

Right temperature

It is common knowledge that pepper plants dislike temperatures below 60 degrees Fahrenheit and that at around 40 degrees, plants might begin shedding leaves. However, they can perish in temperatures as low as 30.

Consider covering pepper plants at night in low-temperature areas to keep them warm. Even if temperatures never get close to freezing, keeping them warm may help prevent leaves from turning yellow.

Wash out chlorine

You can try washing out the chlorine salts from the soil using solely chlorine-free water if too much chlorine is what’s creating the yellow foliage. You can obtain chlorine-free water by collecting rainwater or allowing tap water to sit for a few days until it dechlorinates.

Why are my pepper plants turning yellow and dying?

Growing your own pepper plants may be fun and economical, whether you cultivate bell peppers, other sweet peppers, or chili peppers. However, it might be baffling for gardeners when the leaves of pepper plants turn yellow because of the following reasons:

Water stress

Inconsistent watering causes water stress, which leads to yellow foliage, decreased pepper yield, and stunted growth. Being constant with your watering is the best course of action because overwatering or underwatering stresses the plants out.

Nutrient deficiency

One of the essential nutrients needed for plant growth is nitrogen. In the absence of nitrogen, your plant will transfer the remaining nutrients to the fresher leaves at the top of the plant, causing the older leaves to become yellow. Eventually, your plant’s leaves will entirely fall off.

Your plants’ growth and development depend heavily on calcium, particularly the formation of their cellular walls. Therefore, your plant will have trouble bearing fruit and absorbing more nutrients if your soil is deficient in calcium.


Your pepper plants may have yellow leaves for another cause, such as a disease that has affected them. The following illnesses can result in yellowing leaves:

  • Phytophthora blight
  • Wilt
  • Bacterial leaf spot


Your plants’ leaves may be yellow if you have an insect infestation. You can tell if bugs are the issue by carefully inspecting your leaves.

Several pests, such as these, could result in yellowing leaves:

What do Overwatered bell pepper plants look like?

Wilted leaves, which may appear to indicate that the plant needs water when it is actually receiving too much of it, are a sign of an overwatered bell pepper plant. Overwatering is one of the primary causes of occasionally slow or stunted plant growth. Another typical indication that your plants are being overwatered is if you find that the leaves of your pepper plants are beginning to curl.

Why are my pepper plants turning light green?

The oldest leaves of a pepper plant will become yellow when there is insufficient nitrogen, while the remaining leaves may turn light green. Pepper leaves may also become lighter or yellower if they have insufficient amounts of iron, manganese, molybdenum, or zinc.
