What Temperature Is Too Hot for Tomato Plants?

Tomato plants can survive and thrive in a wide range of temperatures, but there is a point where the heat becomes too much for them to handle. When the temperature rises above 95 degrees Fahrenheit, tomato plants may start to wilt, and their leaves may turn yellow or brown. If the heat continues, the plants may stop producing fruit altogether.

When Should You Cover Your Tomato Plants?

It is best to cover your tomato plants when the temperature is forecasted to be above 95 degrees Fahrenheit for an extended period of time. This could be a few days or a week or more. By providing shade to your tomato plants, you can help to keep them cooler and prevent them from wilting or dying. Covering can also protect the plants from other extreme weather conditions like hail and heavy rain.

What Should You Use to Cover Your Tomato Plants?

There are a variety of materials you can use to cover your tomato plants, including shade cloth, old sheets, towels, or burlap. It is important to make sure that the material you choose allows for adequate air circulation, as tomato plants need good air flow to thrive. You also want to make sure that the material is not touching the leaves of your plants, as this can cause damage or introduce disease.

How Should You Cover Your Tomato Plants?

When covering your tomato plants, you want to make sure that the material is securely fastened and not at risk of blowing away. You can use clothespins, stakes, or string to secure the material in place. It is also a good idea to cover your tomato plants during the hottest part of the day, which is typically between 11am and 4pm.
