Introduction

Tomatoes are a popular garden crop that requires proper care in order to thrive and produce a healthy yield. One of the most important factors to consider when growing tomatoes is heat tolerance. In this article, we will explore how much heat tomato plants can tolerate.

The Optimal Temperature Range for Tomatoes

The optimal temperature range for tomato plants is between 70-80 degrees Fahrenheit during the day and 60-70 degrees Fahrenheit at night. When temperatures are within this range, tomato plants are able to photosynthesize and develop properly. Temperatures outside of this range can result in stunted growth, poor fruit production, and other issues.

Heat Stress in Tomato Plants

When temperatures rise above the optimal range, tomato plants can experience heat stress. Symptoms of heat stress include wilting, leaf curling, and browning of leaves. In severe cases, heat stress can cause blossom drop and fruit deformities.

How Much Heat Can Tomato Plants Tolerate?

Tomato plants can typically tolerate temperatures up to 95 degrees Fahrenheit during the day and 85 degrees Fahrenheit at night. However, this tolerance can vary depending on a variety of factors such as humidity and other environmental conditions. High temperatures combined with high humidity can be especially stressful for tomato plants and result in rapid wilting and other symptoms of heat stress.

Protecting Tomato Plants from Heat Stress

Fortunately, there are several measures that gardeners can take to protect their tomato plants from heat stress. One of the easiest ways to prevent heat stress is to provide shade for tomato plants during the hottest part of the day. Gardeners can use shade cloth or strategically plant taller crops to provide shade for tomato plants. Additionally, watering tomato plants deeply and frequently can help to cool the soil and provide much needed moisture for the plants during hot weather.

Conclusion

Tomato plants are sensitive to heat and can quickly suffer from heat stress when temperatures rise above their optimal range. By understanding how much heat tomato plants can tolerate and taking steps to protect them from heat stress, gardeners can ensure a healthy and productive crop of tomatoes.
