What Temperature is Bad for Tomato Plants

Tomato plants are one of the most commonly grown plants in home gardens. They are loved for their delicious and versatile fruit that can be used in many dishes. However, these plants can be quite sensitive to temperature changes. In this article, we will discuss what temperature is bad for tomato plants and how it can affect their growth and yield.

Temperature Range for Tomato Plants

Tomato plants require specific temperatures to grow and produce fruit. They thrive in warm weather and can withstand temperatures as high as 85°F (29°C) during the day and 50°F (10°C) at night. The ideal temperature range for optimum growth of tomato plants is between 65°F (18°C) and 80°F (27°C). If the temperatures fall below or rise above this range, tomato plants can start to show negative effects.

Effects of High Temperatures on Tomato Plants

When temperatures rise above 85°F (29°C), tomato plants can start to experience heat stress. This can cause the plants to wilt and even stop growing. High temperatures can also affect the quality of the fruit, causing it to ripen too quickly and become mealy or bland in taste. In some cases, tomatoes can become sunburned and damaged.

Effects of Low Temperatures on Tomato Plants

Temperatures below 50°F (10°C) can also have a negative effect on tomato plants. When exposed to these low temperatures, tomato plants can stop growing and even die. Cold temperatures can also cause the fruit to turn black or brown and become mushy.

How to Protect Tomatoes from Extreme Temperatures

There are several ways to protect tomato plants from extreme temperatures. One way is to provide shade during hot weather. This can be done by using shade cloth or by planting taller plants nearby that can provide shade. During cold weather, tomato plants can be covered with blankets or plastic to keep them warm. Another way to protect tomato plants is to water them regularly. This can help cool down the plants during hot weather and help prevent frost damage during cold weather.

In Conclusion

Tomato plants require specific temperatures to grow and produce fruit. Temperatures outside of the optimal range can have negative effects on the plants, including wilting, fruit damage, and even death. By understanding what temperature is bad for tomato plants and taking steps to protect them, home gardeners can ensure a healthy, successful crop of delicious tomatoes.
