Even if the fiery chili prefers it warm, it can survive our domestic winters. We show how to successfully overwinter chillies.
In their original home in Central and South America, chillies (Capsicum) are spoiled by the sun and warmth. There is no winter there. With us, however, already - and very cold and frosty. Since the plant is not used to it, a few things have to be considered so that chillies survive the winter well here too. In our article you will find out when the chili gets too cold and how you can overwinter chillies in the garden and in the pot.
Because of their sensitivity to frost, chilies are usually only grown once a year. But that doesn't have to be the case, because unlike tomatoes, for example (Solanum lycopersicum), chillies are perennial plants. In the right place, the chilli can even bear fruit all year round.
Chilis belong to the nightshade family (Solanaceae) and to the genus Capsicum . There are an incredible number of chili varieties worldwide, which are essentially assigned to five Capsicum species. So that you don't have to do without fresh chillies in winter, we'll give you a few tips and tricks on how to properly overwinter chillies.
When does the chilli get too cold?
Chilis love warmth and die even in a light frost. If the temperatures fall below 14 °C at night, most chillies grow much more slowly. From temperatures permanently below 10 °C, most types of chili lose their leaves and look sickly and unhe althy. The chili species Capsicum chinense is very sensitive to cold and does not tolerate temperatures below 13 °C. Tree chillies, on the other hand, are a little less sensitive. Chilies of the species Capsicum pubescens, which also includes the tree chili, can even withstand night-time temperatures of up to 8 °C.
Wintering the chilli outside
Because the temperatures are well below 10 °C even in autumncan fall, overwintering chillies outside is almost impossible. The only way to overwinter chillies in the garden is in a heated greenhouse. Here you can regulate the temperature and ensure that your chillies never get too cold, even in winter.
Wintering the chilli in the pot
Overwintering chillies in a pot is much safer. Here you can make sure that your chillies are warm enough. Nevertheless, leave the chillies outside in a sheltered place for as long as possible. If the temperatures then drop permanently, it is time for the chili to move. Now you have two options for overwintering your chillies: in a warm, sunny place or in a cooler place. Ideally, you overwinter your chillies in a cool, bright room. Temperatures between 10 and 15 °C are optimal. However, it should never get colder than 10 °C.
If the chili is wintered cold, it will not bear any fruit during this time. But he can gather strength for the new season during the hibernation. Alternatively, you can overwinter your chillies in a warm, sunny place, for example in a bright conservatory, in a heated greenhouse or in a warm place on a sunny windowsill. The temperatures here should also be a maximum of 20 °C. You should keep the light and temperature conditions as constant as possible throughout the winter. Then there is the possibility that the plant will also produce flowers and bear fruit over the winter. Too little light causes the plant to wither. Please also note that the chili is much more susceptible to pests, especially spider mites, if it is overwintered warm.
Overview of wintering of chili:
- Cool and bright is best
- Temperatures between 10 - 15 °C
- Never frost or temperatures below 10 °C
- Alternatively overwinter at max. 20 °C

Caring for chillies in winter
Proper care during the winter also plays an important role. When you bring the chili plant indoors, the soil in thepot should be as dry as possible. If the soil is too wet, the roots can quickly become moldy. Less care is required if the plant is kept cool over the winter: you should only make sure that the soil in the pot is never wet, but rather dry to slightly damp. However, the pot should not dry out completely. The fertilization is completely stopped in winter. If the chili stays warm throughout the winter, you have to do a little more to ensure that your plant is doing really well. Water them regularly and also spray them with water. Chilies prefer a humidity of over 50%. If the humidity is lower, they can dry out too easily. On the other hand, if the humidity is too high, this can promote mold and pest infestation. Chillies don't like dry heating air either. Dry or dead plant parts should be removed regularly. It is also advisable to regularly check your chili for pests. Aphids and spider mites in particular bother the chilli in winter.
Summary of caring for chillies in winter:
- Never keep the soil too moist, but also don't let it dry out
- Set fertilization
- Spray regularly with water
- Humidity over 50%
- Check the plant regularly for pests
Once the winter is over, you can slowly prepare the chillies for summer again. From mid-February to early March, the plants are then placed a little warmer and watered more regularly. In addition, the chili is cut back and repotted in spring.
If the chillies have been overwintered successfully, a new summer and a new chilli harvest are imminent. You can read five tips to make chillies really hot here.
