How Cold is Too Cold for Pepper Plants at Night?

It is generally recommended that pepper plants not be exposed to temperatures below 50°F (10°C). However, some varieties can tolerate temperatures as low as 40°F (4.5°C), so it really depends on the plant. If the temperature is expected to dip below 50°F, it’s best to take precautions such as covering the plants or bringing them indoors.

Temperatures below 40°F can damage or kill pepper plants, so those should be avoided if possible.

Can Peppers Survive 40 Degree Weather?

Yes, peppers can survive 40 degree weather. Peppers are a warm-weather crop, so they can tolerate temperatures as low as 40 degrees Fahrenheit. However, they will not thrive in temperatures that are below 50 degrees Fahrenheit.

If the temperature dips below 40 degrees Fahrenheit for an extended period of time, the peppers will start to experience damage. The leaves will turn yellow and the plants will stop growing. If the temperature remains at or below freezing for more than a few days, the plants will die.

Can Pepper Plants Survive 35 Degrees?

Yes, pepper plants can survive 35 degrees. In fact, they can thrive in temperatures as low as 30 degrees. Peppers are a warm weather crop and do best when the temperature is between 70-80 degrees during the day and 60-70 degrees at night.

They will start to experience stress when the temperature gets below 60 degrees. When the temperature drops below 50 degrees, their growth will stop completely. Peppers can tolerate short periods of time in temperatures as low as 35 degrees, but if the temperature remains cold for more than a few days, they will begin to die.

When Should I Bring My Pepper Plants Inside?

When the average daytime temperatures start to drop below 55°F, it’s time to start thinking about bringing your pepper plants inside for the winter. Peppers are tropical plants and cannot tolerate frost, so if you live in an area that experiences any freezes during the winter, it’s best to err on the side of caution and bring them indoors. Before you bring your pepper plants inside, give them a good cleaning.

Rinse off all the dirt and debris from their leaves and stems with a hose or a gentle stream of water from the sink. Once they’re clean, inspect them for any signs of pests or diseases. If you see anything concerning, treat the plant accordingly before moving it indoors.

Once your plants are clean and healthy, find a sunny spot for them inside. A south-facing window is ideal, but anywhere that gets 6-8 hours of sunlight per day will work. If you don’t have any windows that get that much sun, you can supplement with grow lights.

Just be sure to position the lights so they’re about 6 inches above the tops of the plants. Water your pepper plants as needed to keep the soil moist but not soggy. You may need to water more frequently than usual when they first come indoors since indoor air tends to be drier than outdoor air.

Also, keep an eye out for signs of stress like wilting leaves or yellowing foliage – this could be an indication that they’re not getting enough light or too much/too little water.

Don't Underestimate The Cold Hardiness of Peppers!

Pepper Plants Nighttime Temperatures

Pepper plants are very sensitive to temperature changes and need a warm environment to thrive. During the day, they can tolerate temperatures in the mid-80s Fahrenheit, but at night, they prefer it to be 10 degrees warmer.

To keep your pepper plants happy, make sure they have a spot in your home that gets plenty of sunlight during the day and is protected from drafts at night. A south-facing window is ideal. You can also use grow lights to supplement natural sunlight if necessary.

How Cold Can Bell Pepper Plants Tolerate

Bell peppers are a warm weather crop, and can’t tolerate temperatures below 50°F. They’re usually one of the last vegetables to be planted in the spring, after all danger of frost has passed. However, there are some varieties of bell peppers that are more cold tolerant than others.

If you’re interested in growing bell peppers in cooler weather, look for varieties like ‘Early Bell’, ‘Tasty Green’, or ‘Green Belle’. These varieties can handle temperatures as low as 40°F. To give your plants the best chance of surviving a cold snap, make sure to plant them in well-drained soil.

Is 40 Degrees Too Cold for Pepper Plants

40 degrees is the temperature at which pepper plants start to experience stress. If the temperature drops any lower, the plants will begin to die. Therefore, if you live in an area where the temperature regularly dips below 40 degrees, it is best to grow your pepper plants indoors.

What Temperature Kills Pepper Plants

If you’re thinking of growing peppers, you might be wondering what temperature kills pepper plants. The answer is that it depends on the type of pepper plant. Some peppers can tolerate colder temperatures than others.

For example, bell peppers are more cold-sensitive than jalapeños. When night temperatures dip below 55°F (12.8°C), bell peppers will start to experience damage. Their leaves will turn black and they may drop flowers and fruit.

Jalapeños, on the other hand, can handle temperatures as low as 40°F (4.4°C). So if you’re in a climate with cool nights, you might want to consider growing jalapeños instead of bell peppers. Of course, both types of pepper plants will be damaged if exposed to freezing temperatures for an extended period of time.

So if you live in an area where frost is a possibility, it’s best to grow your peppers under cover or bring them indoors when the temperature starts to drop at night.


Most pepper plants can tolerate cold temperatures as long as they are not exposed to freezing temperatures for an extended period of time. However, there are some varieties of peppers that are more sensitive to cold and can only tolerate brief exposure to low temperatures. If you are growing a variety of pepper that is sensitive to cold, it is important to take steps to protect your plants from the frost.
