What Temperature will Kill New Tomato Plants

Tomatoes are one of the most popular vegetables grown in home gardens. They are easy to grow and can produce an abundant harvest, provided that they receive the proper care. One of the factors that can significantly affect the growth and development of tomato plants is temperature. In this article, we will discuss what temperature can kill new tomato plants.

The Ideal Temperature for Tomato Plants

Tomato plants thrive in warm temperatures. The ideal temperature range for tomato plants is between 70 and 85 degrees Fahrenheit during the day and around 60 degrees Fahrenheit at night. These temperatures will help the tomato plant grow and produce fruit. However, extreme temperatures can have harmful effects on the health of the plant.

The Effects of Low Temperatures on Tomato Plants

Tomato plants are sensitive to low temperatures. Temperatures below 50 degrees Fahrenheit can slow down the growth of the plant and negatively impact the fruit production. If the temperature drops below 40 degrees Fahrenheit, the tomato plant can experience cold stress, which can lead to significant damage or even death of the plant.

The symptoms of cold stress on tomato plants include yellowing of the foliage, wilting, and stunted growth. Additionally, the fruit of the plant can become discolored and crack, making it inedible.

The Effects of High Temperatures on Tomato Plants

While low temperatures can harm tomato plants, high temperatures can be just as harmful. Tomato plants exposed to temperatures above 90 degrees Fahrenheit can experience heat stress. The symptoms of heat stress in tomato plants include wilting, yellowing of leaves, and fruit drop. If the heat stress continues for a prolonged period, the tomato plant can die.

When tomato plants experience extreme temperatures, they become more vulnerable to pests and diseases, which can lead to further damage of the plant.

Protecting Tomato Plants from Extreme Temperatures

One of the best ways to protect tomato plants from extreme temperatures is to plant them in the right season. Tomato plants should be planted in the spring when temperatures are starting to warm up. Additionally, tomato plants can be protected from low temperatures by covering them with a blanket or a row cover. This will help to trap warm air around the plant and prevent frost damage.

Tomato plants can also be protected from high temperatures by providing them with shade. This can be achieved by using a shade cloth or by planting them near larger plants that can provide natural shade. Additionally, watering tomato plants during the hottest part of the day can help to cool the plant and prevent heat stress.

Conclusion

Tomato plants are sensitive to extreme temperatures. Temperatures below 50 degrees Fahrenheit or above 90 degrees Fahrenheit can harm the plant and even kill it. However, by planting tomato plants in the right season and taking steps to protect them from extreme temperatures, gardeners can ensure that their tomato plants grow and produce an abundant harvest.
