Bell peppers need a minimum of 6–8 hours of full sunlight for adequate growth and fruit production. However, depending on the climate, they can require up to 12 hours of sunlight per day.
In full shade, bell peppers don’t produce flowers. Inadequate sunlight can also lead to poor soil aeration and drainage, producing disease and rot within the bell pepper. Good mulching and watering practices can prevent these issues and make it possible to grow bell peppers in indirect sunlight.
Even though they thrive in the heat, bell peppers are also susceptible to sunscald, wilting, and leaf drop if the heat is too intense. Use shade cloths during heat waves to prevent sun damage to bell peppers.

How Many Hours of Sun Do Bell Peppers Need?
Peppers need full sunlight for optimal growth and fruit production. Giving peppers adequate sunlight will enhance fruit production and fruit size. This means 6–8 hours of direct sunlight is the minimum for bell peppers. However, peppers will thrive better in more direct sunlight and can thrive with as much as 12 hours of sunlight per day.
- Bell peppers need 6-12 hours of sunlight per day, depending on the climate.
- Peppers thrive under hot conditions.
- Under extreme temperatures, peppers need adequate protection from sunburn.
Direct sunlight means no shade from other plants or trees. However, both the pepper fruit and plant itself are susceptible to damage from an overdose of sun and extreme heat.
Can Bell Peppers Grow in Indirect Sunlight?
Although your peppers will ideally have access to direct sun, that isn’t always possible. Luckily, peppers can still grow in partial shade. The most significant consequence of indirect sunlight is smaller plants and poor yields.
- Optimal growth for peppers is in direct sun, but peppers can still grow in indirect sunlight.
- The main concern for indirect sunlight is smaller plants and poorer yields.
- Bell peppers need 12-14 hours of indirect sunlight per day to produce larger fruits.
To ensure the production of flowers and growth of fruits, you should expose bell peppers planted in indirect sunlight to 12-14 hours of sunlight per day. In addition, you should prioritize optimal soil conditions and watering schedules. Supplement your indoor plants or garden with artificial light to make sure they produce bell peppers.
Can Bell Peppers Grow in Shade?
Peppers can grow under shade but they may not flower under these conditions. No flowers mean the plant won’t produce any peppers. Thus, it’s always best not to grow bell peppers under full shade. However, there are ways to enhance pepper growth under suboptimal conditions.
- Full shade is not recommended for pepper plants.
- Under full shade, pepper plants may not flower.
- Use this reflective mulching system to enhance pepper growth in full shade.
One of the ways to enhance pepper growth is through a good mulching system. Using either reflective silver plastic mulch or black plastic mulch can retain heat in the soil. This can simulate the hot conditions that cause pepper plants to thrive in full or partial shade.
What Happens if Bell Peppers Don’t Get Enough Sun?
If bell peppers don’t get enough sun, they won’t produce flowers. In addition, peppers are very particular about soil moisture. With inadequate sunlight, poor soil aeration and drainage can develop. Instead of rich, well-drained soil, the soggy soil that develops when sunlight isn’t evaporating excess water can cause the roots of your bell peppers to rot. This can kill your plants.
- Inadequate sunlight can lead to leggy, fruitless pepper plants.
- Poor soil aeration and drainage can develop under inadequate sunlight, making peppers more susceptible to rot and disease.
With poor sunlight, your pepper plants focus on finding the sun for photosynthesis instead of producing fruit. Searching for the sun leads them to become lengthy, “leggy” plants. Even if they produce fruits under this condition, the fruit will be small and vulnerable to pests.
Can Bell Peppers Get Too Much Sun?
As well as being sensitive to inadequate sunlight, bell peppers are sensitive to too much sun. Under harsh sunlight, the leaves and fruit of bell pepper plants can get sunscald, leaving them unharvestable in some cases. Luckily, there are ways to prevent too much sun exposure.
- Too much sun can lead to sunscald, wilting, and leaf drop on bell pepper plants.
- Shade cloths can decrease sun damage up to 40 percent.
Sun damage is caused mainly by the afternoon sun with high irradiance, which usually occurs during early-to-late summer heatwaves. To prevent damage to your bell peppers at this time, place a shade cloth over your bell pepper plants during these times. This shade cloth is optimal for allowing sunlight in but protecting plants from sun damage.
How Much Sun Do Bell Peppers Require?
In most places in the United States, bell peppers require 6-8 hours of sunlight. However, 12 hours of sunlight per day is sometimes better, depending on the climate. Anything less can lead to poor soil aeration, inadequate drainage, and the absence of fruit.
- Bell peppers require 6-12 hours of sunlight per day, depending on the climate.
- Inadequate sunlight affects soil aeration and drainage.
While good watering and mulching practices make it possible to grow bell peppers in the indirect sun, they won’t produce as much as peppers in full sun.
In addition to inadequate sunlight, bell peppers can get too much sun. If the sunlight is harsh, bell peppers are susceptible to sunscald and leaf wilt. You can use shade cloths to prevent sun damage while retaining sunlight exposure.
