What Temperature Do You Need to Cover Tomato Plants?

One of the most important factors in growing healthy tomato plants is ensuring that they are protected from temperature extremes. While tomatoes thrive in warm weather, they can easily be damaged or killed by cold temperatures. Covering your tomato plants can be an effective way to protect them, but knowing what temperature you need to cover them is crucial.

When Should You Cover Tomato Plants?

The optimal temperature to cover tomato plants varies depending on a few different factors. In general, tomato plants should be covered when temperatures drop below 50 degrees Fahrenheit. However, this can depend on the stage of growth of your tomato plants.

If your tomato plants are still seedlings or young plants, it's important to cover them when temperatures drop below 60 degrees Fahrenheit. This is because young plants are more sensitive to temperature changes than mature plants. Once your plants have matured and reached a height of about 12-18 inches, they are better able to tolerate colder temperatures and can handle being uncovered at slightly lower temperatures.

What Should You Use to Cover Tomato Plants?

Covering your tomato plants can help trap in heat and protect them from cold temperatures. There are several different materials you can use to cover your plants, including:

Clear plastic tarps

Frost blankets

Cloth sheets

Row covers

Each of these materials has its own pros and cons, so it's important to choose the right one for your specific situation. For example, clear plastic tarps are more effective at trapping in heat, but they can also overheat your plants on sunny days. Frost blankets and cloth sheets are more breathable, but they may not provide as much protection from extreme cold.

How Should You Cover Tomato Plants?

When covering your tomato plants, it's important to do so properly to ensure they receive the protection they need. Here are some tips for covering your plants:

Make sure the cover reaches all the way to the ground to trap in heat

Avoid letting the cover touch the tomato plants directly to prevent damage

Ensure that the cover is secure and won't blow away in the wind

Remove the cover during the day to prevent overheating

By following these tips, you can help your tomato plants survive even the coldest temperatures.

Conclusion

Tomato plants are susceptible to damage from both extreme heat and cold. Covering your plants can be an effective way to protect them from temperature extremes, but it's important to know what temperature you need to cover them and how to do so properly. By following the tips outlined above, you can ensure that your tomato plants stay healthy and productive throughout the growing season.
