Introduction

Cherry tomato plants are a favorite among gardeners due to their sweet, juicy flavor and ease of care. However, they are sensitive to sudden changes in temperature, especially when it gets too cold. This leads us to the question, how cold can cherry tomato plants tolerate?

The Ideal Temperature Range for Cherry Tomato Plants

Cherry tomato plants thrive in temperatures above 50°F (10°C). They normally grow best in temperatures between 70°F to 85°F (21°C to 29°C). If the temperature goes below 50°F (10°C), the growth of the plant may slow down, and the leaves may turn yellow, eventually leading to the death of the plant.

Cherry Tomato's Cold Tolerance Methods

If you live in a colder climate and still want to grow cherry tomato plants, there are ways to help them tolerate colder temperatures. One option is to use a cold frame. A cold frame works similar to a small greenhouse, but it is designed to be unheated. It provides insulation and protects the plants from the cold. Another option is to use a row cover, which is a lightweight cover that can be placed over the plants to provide a little extra warmth.

Preparing Cherry Tomato Plants for Winter

When winter approaches, it is important to prepare your cherry tomato plants for the cold. One way to do this is to stop fertilizing the plants six weeks before the first expected frost date. This will discourage new growth, which is more sensitive to the cold. It is also important to remove any dead leaves from the plant and to prune it to reduce its size, making it easier to protect from the cold.

Cherry Tomato Plants' Frost Tolerance

Cherry tomato plants can tolerate a light frost of 29°F to 32°F (-2°C to 0°C) for a short period. However, a hard frost, which is below 28°F (-2°C), will normally kill the plant. If you expect a hard frost, it is essential to protect the plant. The easiest way to do this is to cover the plant with a blanket or tarp. It is also a good idea to water the plant before the frost as the moisture will help to insulate it.

Conclusion

In summary, cherry tomato plants prefer temperatures between 70°F to 85°F (21°C to 29°C). If the temperature drops below 50°F (10°C), the growth of the plant may slow down, and the leaves may turn yellow. Cherry tomato plants can tolerate a light frost of 29°F to 32°F (-2°C to 0°C) for a short period, but a hard frost, which is below 28°F (-2°C), will kill the plant. To avoid this, it is essential to take precautions such as using a cold frame or row cover and pruning the plant to reduce its size. By following these tips, you can ensure your cherry tomato plants will thrive even in colder temperatures.
