Will Tomato Plants Survive at 45 Degrees?

Tomatoes are one of the most popular vegetables globally, but they are more sensitive to extreme environmental factors. One of the facts that most gardeners concerned about is whether tomato plants will survive at 45 degrees temperature. Tomato plants need adequate sunlight, moisture, and nutrients to grow healthily. High temperature can reduce proper growth and productivity, which is a significant concern. In this article, we will discuss whether tomato plants can survive at 45 degrees temperature or not.

The Effect of High Temperatures on Tomato Plants

Tomato plants thrive in warm weather, but not all high temperatures are the same. Air temperature above 32 to 35 degrees Celsius can reduce the quality and yield of the tomato fruits. If the temperature is around 45 degrees Celsius, it can cause severe damage to the plants, leading to stunted growth, wilted leaves, and brown leaves' tips. Extreme heat can cause excessive water loss through the leaves, wilting, and even death of the plant. Therefore, a temperature of 45 degrees Celsius can significantly affect tomato plants' growth if it happens for an extended period.

Factors Affecting Tomato Plants' Survival

While high temperatures are an essential aspect to consider, the survival of tomato plants is also dependent on the length of the exposure, the stage of growth, and the genetic makeup of the plant. Mature tomato plants are more resilient to harsh weather than young plants. Young plants have smaller roots and leaves, which leads to low water and nutrient uptake. This, in turn, causes stress to the plant; hence, it becomes vulnerable to any form of harsh weather, including high temperatures. Though mature plants can tolerate high temperatures, a prolonged period of exposure can cause severe damage.

How to Protect Tomato Plants from High Temperatures?

Gardeners can protect tomato plants from high temperatures by using appropriate measures. One of the most effective methods is shading. Tomato plants can be shaded by covering the plants during the hottest part of the day. Another method is through watering the plants frequently to keep the soil evenly moist. Mulching can also help to prevent moisture loss and keep the soil temperature stable. Adequate watering is necessary since high temperatures increase water loss through the leaves. Gardeners can also consider relocating planting in areas where the tomato plants receive partial shade or construct greenhouses with a controlled environment.

Conclusion

Tomato plants are sensitive to high temperatures, and a temperature of 45 degrees Celsius can significantly affect their growth and yield. The effect of high temperatures on tomato plants depends on several factors, including the stage of growth, length of the exposure, and genetic makeup. Gardeners can protect their tomato plants from high temperatures through shading, frequent watering, mulching and constructing greenhouses with a controlled environment. Therefore, protecting tomato plants from high temperatures is crucial for productivity and yield.
