Are Tomato Plants OK at 50 Degrees?

Tomato plants are known to be heat-loving plants. They thrive in warm temperatures and grow best in conditions where the temperature ranges from 70 to 80 degrees Fahrenheit. However, there are times when the temperature drops, and gardeners would begin to wonder whether their tomato plants would still be able to survive at 50 degrees Fahrenheit.

What Happens to Tomato Plants at 50 Degrees?

When the temperature drops to 50 degrees Fahrenheit, tomato plants may experience stunted growth. This is because the cooler temperature slows down the activity of enzymes in the plant, causing a decrease in the rate of photosynthesis. As a result, the tomato plant may not be able to produce as much energy as it requires, and its growth will suffer.

Furthermore, the cooler temperature may cause the tomato plant to become more susceptible to diseases and infections. This is because the cooler temperature prevents the plant from producing certain compounds that help combat pathogens, leaving it more vulnerable to attack.

Can Tomato Plants Survive at 50 Degrees?

Although tomato plants may experience stunted growth and increased susceptibility to diseases and infections when subjected to cooler temperatures, they are still able to survive at 50 degrees Fahrenheit. However, it is best to prevent the temperature from dropping below 55 degrees Fahrenheit if possible, to avoid any potential harm to the plant.

One way to protect tomato plants from cooler temperatures is to cover them with a blanket or row cover. This will help trap heat and maintain a warmer temperature around the plant.

Tips for Growing Tomato Plants in Cooler Temperatures

Here are a few tips to help you grow tomato plants in cooler temperatures:

Plant tomato plants in a sheltered location or near a warm wall that can reflect heat back onto the plant.

Cover the plants with a blanket or row cover to retain heat.

Water tomato plants in the morning so that the foliage has time to dry before the temperature drops in the evening. Wet foliage can lead to frost damage when the temperature drops.

Choose tomato varieties that are known to be more tolerant of cooler temperatures, such as 'Celebrity' and 'Early Girl'.

Conclusion

Although tomato plants prefer warmer temperatures, they are still capable of surviving at 50 degrees Fahrenheit. However, it is best to prevent the temperature from dropping below 55 degrees Fahrenheit if possible, to avoid any potential harm to the plant. By following the tips outlined above, you can successfully grow tomato plants in cooler temperatures and enjoy a bountiful harvest.
