Why are the leaves of your pepper plant falling off? In this article I explain some possible causes of the fall of the pepper leaf.

But beware, many causes are easy to remove! In most cases, your plants fully recover and can be in perfect health, even if some leaves are soft.

It’s only natural that a few leaves fall off your plants here and there, but this article should help you discover the cause. In case of more serious problems, correcting plant care can save your peppers in the long run.

Natural leaf fall

I’ll start with the most likely and least threatening cause of the pepper leaf fall. As the pepper plants age, some leaves age and die naturally.


  • The lower leaves die at random
  • Yellow on different leaves

If most of your plant’s leaves look healthy, natural leaf death is likely to be the cause. Nothing to worry about! As long as the amount of falling leaves is relatively small, there is no cause for concern.

This occurs mainly because of the age of the pepper plants. New leaves take precedence over old ones. It is also possible that some leaves are damaged, causing leaf death.

Nutrient deficiencies

The most common nutrient deficiency is nitrogen. If the plants lack the necessary nitrogen, the leaves turn yellow and eventually fall off.

Nitrogen is a mobile nutrient, which means that the plant can move it to the parts of the plant that need it most. This results in yellowed paprika leaves at the base of the nitrogen-poor plant, which eventually migrate upwards.

Other possible shortages include calcium, magnesium, phosphorus, potassium and sulphur. If you grow in pots, it’s more likely.

Harmful organisms

Some sweet peppers suck the juice from the leaves of the sweet pepper plant. Others just chew holes in the leaves. In any case, parasites can certainly cause a leaf fall.

  • curl sheets
  • Brown spots on leaves or stems
  • Visible pests (especially under the leaves)

If you suspect the presence of parasites, you must first find and identify them. Check the underside of the leaves, especially new leaves. Some pests also gather around new flower buds.

Some pests are easier to control than others. Aphids can be sprayed with a hose, while snails and caterpillars have to be removed by hand. Prevention is the key, so try to plant certain crops next to peppers to attract the right insects.

Leaf drops on peppers can also be a natural reaction to environmental factors. Peppers are leafy, just like trees drop their leaves in autumn.

Incorrect corrections

Excessive watering is the best way to avoid the cultivation of peppers. The peppers even need water, but too much can be disastrous. Without proper drainage, the root system essentially drowns.


  • curl sheets
  • yellow leaves
  • Root rot

If you plant in pots, make sure there are holes in the bottom of the pot for proper drainage. Terrestrial plants should be planted on mounds to let the rain run off the roots.

Diving is best tolerated by paprika plants, but should be avoided if possible. In serious cases, this can cause the leaves of the peppers to fall off.

When it is very hot, peppers drink a lot more water, especially when they are ripe. Feel the first inch of the ground for moisture before watering.

Make sure you add some organic material to the soil each year at the beginning of the season.

The dosage of organic matter in the soil helps to maintain a uniform moisture level.

Solar shock

When peppers are moved outside in direct sunlight, the paving must be removed. It is a process of gradual adaptation of plants to increasing amounts of direct sunlight.

  • White or brown on the leaves
  • Dried and dehydrated leaves (crispy texture)

No matter how strong your illumination is, the sun shines brighter. Although sweet peppers grow best in full sun, delicate seedlings should never be moved outdoors without a transitional period.

To harden the peppers, start with 15-20 minutes of direct sunlight and then place the plants in the shade. After a few days, increase exposure to the sun to 30-45 minutes and so on. After 3-4 weeks, your plants should be able to endure the full sun all day long.

Cooling temperature

In many climates, early autumn brings a nocturnal chill. Peppers come from warm, almost tropical climates, which means that the cold weather is bad.

Paprika’s dead from cold pepper after freezing.


  • Leaves that fall randomly all over the plant.
  • General dilution of plants

In response to cooler temperatures, sweet pepper plants can lower some of their leaves to reduce exposure and perspiration. She can help them get through a cold night. However, at temperatures below freezing most varieties of paprika simply die.

While waiting for a cold night (less than 50°F), use a garden towel or plastic foil to protect the pepper plants from the cold.


The last possible cause of leaf drop in peppers is disease. There are a number of diseases that can infect your plants and cause the leaves to fall.

  • Round spots on leaves
  • Fuzzy fungus on leaves

If there are spots on the leaves that seem to repeat themselves or have a pattern, your plant may be infected. The best way to prevent many diseases is to keep the lower leaves out of the ground.

Another method of prevention is to keep the plants as healthy as possible. Just like humans, a healthy body is better able to fight diseases and viruses. Keep the floor healthy!
