What Temperature to Cover Tomato Plants

Tomato plants are a common addition to gardens and farms throughout the world, but they can be sensitive to changes in temperature. One of the most common ways to protect tomato plants from extreme temperatures is to cover them. But what temperature is the best temperature to cover tomato plants?

When to Cover Tomato Plants

Before we get to the temperature at which to cover tomato plants, we need to talk about when to cover them. Tomato plants should be covered when temperatures drop below 50 degrees Fahrenheit or rise above 90 degrees Fahrenheit. Anything below 50 degrees Fahrenheit can damage the plants, while anything above 90 degrees Fahrenheit can cause them to wilt and become dehydrated.

What Temperature to Cover Tomato Plants

The optimal temperature to cover tomato plants is 32 degrees Fahrenheit. At this temperature, the plants are at risk of freezing, which can cause significant damage or even kill them. By covering them, you can protect them from the cold and ensure that they continue to grow and produce healthy fruit.

However, it's important to note that not all coverings are created equal. If you're using blankets or tarps to cover your tomato plants, you'll need to make sure they're secured tightly to prevent them from blowing away or causing damage to the plants. Alternatively, you can use more specialized coverings, such as frost cloths or row covers, which are designed to protect plants from cold temperatures.

Other Factors to Consider

While temperature is a crucial factor to consider when covering tomato plants, there are other factors that can also play a role in their survival. For example, if the soil is too dry or too wet, the plants may be more susceptible to damage from the cold or heat. Additionally, if the plants have already been stressed by pests, diseases, or other factors, they may not be able to withstand extreme temperatures as well as healthy plants.

It's also important to note that covering tomato plants can have some downsides. For example, if the plants are covered for too long, they may become too humid and susceptible to fungal diseases. Additionally, covering can also prevent pollinators from accessing the flowers, which can reduce the yield of the plants.

Conclusion

When it comes to protecting tomato plants from extreme temperatures, covering them can be an effective strategy. The optimal temperature to cover tomato plants is 32 degrees Fahrenheit, but it's important to keep in mind that not all coverings are created equal. Additionally, other factors such as soil moisture, plant health, and pollination can also play a role in the health and survival of tomato plants.
