What Temperature will Hurt Tomato Plants

Tomato plants are a staple in many gardens, and they are fairly easy to grow with the right conditions. However, one thing that can be detrimental to tomato plants is extreme temperatures. So, what temperature will hurt tomato plants? Let's take a closer look.

Optimal Temperature for Tomato Plants

The optimal temperature range for tomato plants is between 65°F and 85°F, with 75°F being the ideal temperature. This temperature range allows for optimal growth and fruit set. When temperatures exceed or fall below this range, tomato plants can struggle to grow and produce fruit.

Temperature Extremes

Temperatures that go beyond the optimal range can harm tomato plants. When temperatures exceed 90°F, tomato plants can experience heat stress. At this temperature, tomato plants have difficulty taking up water, which can lead to wilting, leaf drop, and blossom drop. High temperatures can also inhibit pollination and lead to reduced fruit set.

On the other end of the spectrum, temperatures that fall below 55°F can cause cold stress in tomato plants. At this temperature, tomato plants can experience stunted growth, leaf discoloration, and even death. Additionally, cold temperatures can inhibit pollination and lead to reduced fruit set.

Protecting Tomato Plants from Extreme Temperatures

There are several steps you can take to protect your tomato plants from extreme temperatures. One way is to provide shade during hot weather. This can be done by using shade cloth or planting in a location with afternoon shade. Additionally, you can water your plants more frequently during hot weather to help them take up more water.

To protect your tomato plants from cold weather, you can use protective coverings such as row covers or blankets. These coverings can help trap heat around your plants and protect them from cold temperatures. Additionally, you can plant your tomatoes in a location with good drainage to prevent water from pooling around the roots and potentially freezing.

Conclusion

Overall, it is important to be mindful of the temperature conditions that your tomato plants are exposed to. Extreme temperatures can harm tomato plants and inhibit their growth and fruit production. By providing the right conditions and taking necessary precautions, you can help your tomato plants thrive and produce a bountiful harvest.
