What Temperature Do You Cover Tomato Plants?

Tomatoes are one of the most beloved and commonly grown plants in home gardens all over the world. As such, it's important to take good care of them by protecting them from harsh weather conditions. One way to do this is by using covers. But what temperature should you cover your tomato plants?

Understanding Tomato Plants

Before we dive into the ideal temperature for covering tomato plants, it's essential to understand a few things about the plants first. Tomatoes are warm-season plants that thrive in warm temperatures, with the optimum temperature range for growth being between 70-85°F (21-29°C). Anything below 50°F (10°C) may cause chilling injury, while temperatures above 95°F (35°C) can inhibit pollination and fruit set.

When Should You Cover Tomato Plants?

Now that we understand what temperatures are ideal for tomato plants, it's easier to determine when to cover them. The primary reason for covering tomato plants is to protect them from extreme weather conditions. If temperatures are expected to drop below 50°F (10°C), covering your tomato plants with a frost cloth or blanket becomes a necessity, as prolonged exposure to such temperatures can damage both the foliage and fruit. However, if the temperatures are only expected to dip slightly below this range, covering isn't entirely necessary. In fact, it's best to avoid overheating the plants and limiting their access to light.

What Temperature Should You Cover Tomato Plants?

As a general rule, tomato plants should be covered if the temperature is expected to drop below 50°F (10°C). Most frost cloths or blankets are designed to provide a few degrees of insulation, which is usually enough to keep your tomato plants safe from prolonged exposure to chilly temperatures. However, if the weather becomes exceptionally cold, even with the covers, it's best to bring your tomato plants indoors or to a warmer location.

Other Tips for Protecting Tomato Plants

Aside from covering your tomato plants, there are other things you can do to protect them from harsh weather conditions. For instance, always make sure to incorporate compost and other organic matter into the soil before planting your tomato plants. This helps to improve the soil's ability to retain moisture, which is essential for healthy plant growth. Additionally, make sure to keep your tomato plants well-watered, especially during hot and dry weather. Avoid over-watering, though, as this can lead to root rot.

Finally, make sure to keep an eye on your tomato plants for signs of stress or disease. If you notice any wilting, yellowing, or browning of the leaves, it may be a sign of a problem that needs to be addressed. In such cases, consult with a gardening expert or seek advice online on the best ways to address the issue.

In Conclusion

To sum it up, covering your tomato plants is an excellent way to protect them from harsh weather conditions, especially if temperatures are expected to dip below 50°F (10°C). However, if the temperatures are only expected to drop slightly below this range, covering may not be necessary. Always make sure to keep an eye on your tomato plants and take proper care of them to keep them healthy and thriving.
