Pepper Plant Flowers Turning Brown (Causes & Solutions)

If you find your pepper plants flower brown in colour, you need to understand that there have something wrong. However, I am going to discuss 7 core reasons and solutions so that you can save the flowers as well as the plants.

1. Extreme Hot Temperature

First of all, the pepper plant doesn’t tolerate excess temperature. The plants need moderate temperatures for proper growth. Hot temperatures reduce the viability of the pollen that causes the brown colour flower of your pepper plant.

The pepper plant climate should be between 70 to 85 degrees F temperature. If the temperature becomes extremely hot, the leaves or other parts of the plants fall down.


To protect the pepper plant from hot temperatures, you can take some steps. Check out the following tips and applied them to protect the pepper plant from the excess hot temperature.

  • First of all, you need to provide enough water from time to time
  • Try to make a shade on the top of the pepper plant to reduce heat
  • Keep watering the oil at least two times a day

2. Poor Pollination

Pollination is always an important factor for plants. The pepper plant is not self-pollinated and it needs other things to complete the pollination. When the plants get lack pollination, they don’t get enough nutrition and other elements which makes the flowers brown and others.


To solve the pollination problem, you can open the space near the plant so that bees and other insects come out and complete the pollination. If possible, plant another pepper near your pepper tree.

3. Insects & Pests

Insects and pests created infections in the flowers and damaged the flowers. Some of the insects and pests created toxic elements on the flower which makes the flowers brown color and finally damaged the flowers.


You may not avoid insects and pests from your pepper plant. They naturally come out on your plant and love to eat the flowers. However, you can use pest and insect controllers or also use chemicals to avoid insects or pests.

4. Overfertilizing

Undoubtedly, fertiliser is essential for the pepper plant to grow properly and faster. But, overfertilizing is bad enough for the plant. Overfertilization means an increased PH of the soil and also damaged the ecosystem of the pepper plant.


You should avoid overfertilizing first from your pepper plant. If you already added extra fertilizer to the plant, you need to provide enough water and use other things to make a proper balance of fertilizer.

5. Mosaic Virus

Another common problem which attacks the pepper plants and their flower. They created infections in the flowers and make the flowers brown colour. They also damaged the flowers so that the plants don’t produce fruits.


To solve the problem, you can spray neem oil on the affected areas of the plant. It is a natural process and works much better to avoid brown colour issues and killed the Mosaic virus. You will also use another chemical which you will get from both online and offline markets.

6. Excessive Nitrogen

Excessive nitrogen means the pepper plant flowers become yellow in colour. But, sometimes I found brown colour. To know about the nitrogen amount, you can purchase a nitrogen measurement matter and check the plants.


In this situation, you can add fertilizer to solve the nitrogen problem. On the other hand, you can check out the PH level of the soil. If the soil comes with acidity, apply some phosphorus. Similarly, you can also add calcium based on the soil condition of your pepper plant.

7. Humidity Too High Or Low

Pepper plant needs 35% to 70% of humidity for proper growth and to keep them healthy. When the humidity becomes too low, the pollination created problems and the flower’s colour becomes brown. Moreover, too low or too high humidity drops the blossom also.


Pepper plant grows at an ideal temperature. You need to ensure that the humidity is enough and it is not too high or low. You can create shade or other things to avoid extreme or lower humidity.
