Introduction

Tomato plants are an important crop for farmers and gardeners alike. They are relatively easy to grow and provide a delicious fruit that is used in a variety of dishes. However, tomato plants are sensitive to temperature and can easily be damaged or killed if exposed to extreme weather conditions. The question that many growers ask is, will 38 degrees kill tomato plants? In this article, we will explore this question and provide some tips for protecting your tomato plants from extreme heat.

The Impact of Temperature on Tomato Plants

Tomato plants are sensitive to temperature and can be affected by both high and low temperatures. Extreme heat, in particular, can cause significant damage to these plants. When temperatures rise above 85 degrees Fahrenheit, tomato plants will begin to experience stress. This stress can lead to a number of problems, including reduced yields, poor fruit quality, and even death.

One of the main ways that heat affects tomato plants is by inhibiting their ability to produce fruit. When temperatures rise above 95 degrees Fahrenheit, tomato plants may stop producing fruit altogether. This is because the high heat causes the plant to focus on survival rather than reproduction. Additionally, extreme heat can cause the fruit to ripen prematurely or develop sunscald, which can make the fruit inedible.

Will 38 Degrees Kill Tomato Plants?

The short answer is no, 38 degrees Fahrenheit will not kill your tomato plants. In fact, most tomato plants are able to tolerate temperatures as low as 40 degrees Fahrenheit without any issues. However, it is important to note that temperatures below 50 degrees Fahrenheit can slow down the plant's growth and development. This means that if you want to get the most out of your tomato plants, it is best to keep them in temperatures between 50 and 85 degrees Fahrenheit.

On the other hand, temperatures above 95 degrees Fahrenheit can be deadly for tomato plants. This is because the high heat causes the plant to experience stress, which can lead to a number of problems. If temperatures reach 100 degrees Fahrenheit or higher, your tomato plants may die within hours. Therefore, it is important to take steps to protect your plants from extreme heat.

Tips for Protecting Your Tomato Plants

If you live in an area where temperatures regularly exceed 85 degrees Fahrenheit, there are several steps you can take to protect your tomato plants. Here are some tips:

Provide shade: Tomato plants need plenty of sunlight to grow and produce fruit, but too much sunlight can be damaging. Providing shade to your plants during the hottest parts of the day can help to keep them cool and reduce the risk of sunscald.

Mulch: Adding a layer of mulch around your tomato plants can help to keep the soil cool and retain moisture. This can help to reduce stress on the plant and improve its ability to produce fruit.

Water regularly: Tomato plants need plenty of water to thrive, especially during periods of extreme heat. Be sure to water your plants regularly to help them stay hydrated.

Use a fan: Setting up a fan near your tomato plants can help to circulate air and reduce heat stress. This is especially important if you are growing tomatoes in a greenhouse or other enclosed space.

Conclusion

Tomato plants are a valuable crop that can be damaged or killed by extreme heat. While temperatures as low as 38 degrees Fahrenheit are unlikely to harm your plants, it is important to be aware of the impact that heat can have on your crop. By taking steps to protect your tomato plants from extreme temperatures, you can help to ensure a healthy and bountiful harvest.
