Will 39 Degree Weather Hurt Tomato Plants?

Tomatoes are a warm-season crop that requires consistent warm temperatures to thrive. When temperatures are too low or too high, it can negatively impact the growth and health of tomato plants. With temperatures rising, many gardeners may be concerned about how high temperatures will affect their tomato plants. Specifically, gardeners may be wondering if 39-degree weather will hurt tomato plants. In this article, we will explore the potential effects of 39-degree weather on tomato plants.

Effects of Cold Weather on Tomato Plants

Although tomatoes are generally considered a warm-season crop, they can tolerate cooler temperatures to a certain extent. However, when temperatures drop below 50 degrees Fahrenheit, tomato plants may experience stunted growth and reduced fruit production. Additionally, prolonged exposure to cold temperatures can make tomato plants more susceptible to pests and diseases.

39-Degree Weather and Tomato Plants

When temperatures hit 39 degrees Fahrenheit, tomato plants are at risk for damage. At this temperature, the plant's cells can be damaged, leading to leaf and flower drop. If the temperature drops even further, the plant may experience frost damage, which can kill the plant entirely. However, if the temperature only drops to 39 degrees for a short period of time, the plant may be able to recover with little damage.

Protection from 39-Degree Weather

To protect tomato plants from 39-degree weather, gardeners can take several measures. Covering the plants with frost blankets or cloths can help to insulate the plants and retain warmth. Additionally, planting tomato plants in raised garden beds can help to prevent frost damage by allowing cold air to drain away from the plants. Finally, gardeners can consider planting cold-tolerant tomato varieties, such as Siberian or Stupice tomatoes, which are better able to withstand cooler temperatures.

Conclusion

In conclusion, 39-degree weather can potentially hurt tomato plants, as the plants may experience cell damage, leaf and flower drop, and, in severe cases, frost damage. However, with proper protection, such as using frost blankets or cloths and planting in raised beds, gardeners can help to mitigate the effects of cold weather on tomato plants. Additionally, planting cold-tolerant tomato varieties can help to ensure that tomato plants continue to thrive, even in cooler temperatures.
