Brown Spots On Peppers – What To Do

Peppers can be one of the best crops to grow at home. Pepper plants (Capsicum spp.) are delicate annual crops available in sweet, mild, and hot variants. Peppers grow best in the USDA plant hardiness zones 9 and 10 in April, May, and June.

Peppers demand full sun, warm temperatures, and continuously moist soil with sufficient drainage, regardless of type. When you plant peppers, many things can appear to be fine until you see irregularly shaped spots appearing on your mature fruit.

It’s distressing to see a sign of bacterial leaf spot lesions ruin your crops, and infected plants can no longer deliver developing fruit to eat. In our guide, you can learn what are the brown spots on bell peppers, and if it affects the rest of the fruit, leaves, and stems.

Can You Eat Peppers With Bacterial Spot?

Most pepper diseases manifest themselves primarily on the leaves and stems. Bacterial spots and blossom-end rot are two problems that can cause spots on fruit to develop.

Bacterial spot is a term used to describe a bacterial infection.

Bacterial spot affects peppers and tomatoes, causing small brown lesions to appear on the fruits. Because the disease overwinters in plant debris, remove and destroy afflicted plants and rotate tomatoes and peppers to a new section of the garden next season to avoid reinfection.

Blossom End Rot

Blossom-end rot is a disease that causes dark, leathery patches on the ends of fruits on peppers, tomatoes, and other garden crops.

Secondary fungal infection is a possibility with these, drought-induced-induced calcium deficiency causes blossom-end rot, therefore giving enough water treatments and preventing the disease.

Most pepper diseases manifest themselves primarily on the leaves and stems. Bacterial spot and blossom-end rot are two problems that can cause spots on fruit to develop.

Examine the rest of the plant for lesions to distinguish between the two diseases. Bacterial spot affects all portions of the plant above ground, including leaves and stems. Only one section of the fruit is affected by blossom-end rot. (Read Philodendron Goeldii Care Guide)

Pepper Leaves Have Irregular Brown Spots?

Leaf spot is a bacterial disease that affects pepper and tomato plants in the garden and causes uneven dark spots on the leaves.

As a result, the irregular brown spots shape of bacterial leaf spot lesions is uneven.

A severely infected plant with bacterial leaf spot may have irregular dark spots that appear moist or waxy.

Because this disease attacks the pepper plant itself, a heavily affected plant suffers from many problems, including defoliation and fruit loss.

This makes your fruits inedible and results in un significant crop loss. If the irregular brown spots have spread throughout the plant or your fruits, have become infected, remove the entire plant to prevent contamination of your other pepper plants.

Because bacterial leaf spot diseases can also affect tomato plants, it’s important to practice crop rotation and avoid planting a pepper plant or tomatoes in the same spot in your garden for two years in a row.

Examine the rest of the pepper plant for lesions to distinguish between the two diseases.

If the spots have spread throughout the pepper plant or your fruits, have become infected, remove the entire plant to prevent contamination of your other pepper plants.

Always clean any garden tools when you have leaf spot disease.

Are Brown Peppers OK To Eat?

Here is more about growing peppers and the fungal diseases you can find in the pepper plant’s leaves and fruits.

While you can get some pepper varieties that can avoid infection of specific bacterial leaf spot pathogens, it is better to understand pepper plant suffering and some preventative measures to fix issues.

Signs of Blossom End Rot

Sun scalding is frequently confused with this bacterial leaf spot disease. Brown circular lesions at the bottom of bell pepper fruits show brown end rot, which starts as bright green/yellowish spots on the skin.

Large end rot spots can eventually become infected with fungus, and a variety of reasons causes blossom end rot:

  • The most common cause is a lack of calcium in the soil. Bell pepper skin requires calcium to form, and if there isn’t enough calcium, the skin degrades into small soft brown spots.
  • This can be caused by inconsistent watering. Water them just enough, but regularly.
  • You can cause blossom end rot from over-watering, so ensure your whole plant receives 2-4 inches of water every week.
  • Use too much fertilizer on your bell pepper to get more fruit. Will instead damage them. Calcium absorption by plants can be hampered by nitrogen and potassium and caused by an excess of sodium and ammonium.

Treating pepper blossom end rot

Unfortunately, the fruits damaged cannot be revived. So all you have to do now is make your conditions for the following season.

  • Adding eggshells to the afflicted soil is the best way to improve the soil. You can also improve soil condition by adding bone meal.
  • Additions can include Epsom salt, or your plants might benefit from side dressing to help them stay healthy. You can use fertilizers that may be labeled as tomato fertilizer but also work well on bell peppers to produce vigorous foliage and growth.
  • Water your bell peppers regularly and with the desired amounts. Bell peppers require 2-4 inches of water per week to thrive.
  • Apply a thick layer of mulch on the soil to help it keep moisture, especially in the heat, rather than add more water.
  • Instead of ammonia, use nitrate-nitrogen as a fertilizer.
  • Restricted root growth leads to BER on pepper plants as the whole plant takes up less water than it needs.
  • You can provide water to your pepper plants every other day, but only give your pepper plants 2-4 inches of water weekly. Garden irrigation with soaker hoses is an ideal solution as these limit symptoms of leaf damage yet allow the soil to keep enough moisture.

You can eat your pepper with blossom end rot if you want to eat your pepper with blossom end rot. First, cut off the affected area and use it as usual. This fruit rot lacks calcium, not a disease; just check there are no brown spots inside bell pepper before using. (Read Aloe Plant Turning Brown)


A common reason for multiple problems is a fungal pathogen. It creates brown, circular lesions on nearly every part of the plant, but if the fruits are harmed, it is the most common reason for losing the fruit and heavy crop loss.

  • It appears on the sides of fruits, and symptoms start like water-soaked lesions and gradually turn brown to black on the affected part.
  • Because the sick plant and all of its residues can harm nearby plants, remove it from the garden. It can also be found in other types of peppers.
  • Ensure your peppers are free of any fungal illnesses before planting another batch. Seeds can spread the infection.
  • With bell pepper, there are no resistant varieties. However, Anthracnose can be avoided by planting varieties with a shorter ripening period.
  • Insects and other pests should be kept at bay, as wounds increase the chance of Anthracnose infection. To successfully control the infection, several fungicides can be used.

Sun Scald

The skin of developing bell pepper fruits is sensitive, and many varieties of bell peppers become browned because of the high temperatures from the hot sun. Heat affects the skin, and the sun aggravates the condition.

  • Sun scorching symptoms are white to dark lesions on the plant’s fragile portions. In addition, bacteria and fungus may exacerbate the damage.
  • Replace the plant with a strong foliage variety, and the leaves will handle any excess heat or sunlight. If you want to keep your fruits in the shade, you can use some straw or a screen.
  • Take care of your leaves; wilted or damaged leaves can’t protect fruits from the sun. Plant your bell peppers in a location where they will receive just enough sunlight, but not the same area the following year to avoid infection.
