Introduction:

Tomato plants are one of the most widely grown vegetables in gardens around the world. As a relatively easy and rewarding plant to grow, they can produce a bountiful harvest of juicy, delicious tomatoes. However, these plants are susceptible to a variety of temperature-related problems that can severely impact their growth and yield. This article will explore the question of what temperature tomato plants should be covered to protect them from cold weather.

Factors Affecting Tomato Plant Growth:

Tomato plants require specific temperature ranges to grow and produce fruit. The ideal temperature range for tomato plant growth is between 70-85°F during the day and 60-70°F at night. Temperatures below or above these ranges can negatively impact plant growth, flowering, pollination, and fruit set. When temperatures fall below 55°F for an extended period, tomato plants can become stunted, experience slow growth, and their leaves may turn yellow. In severe cases, frost or freezing temperatures can cause leaves, stems, and fruit to become damaged or die.

Protecting Tomato Plants:

When temperatures drop below the recommended ranges, tomato plants require protection to ensure their survival and continued growth. One way to protect tomato plants is to cover them with plastic or fabric that can provide insulation against cold temperatures. Plastic covers are ideal as they trap heat and create a mini greenhouse environment around the plants. This helps to keep the temperature around the plants warmer than the surrounding air temperatures.

The Optimal Time to Cover Tomato Plants:

The best time to cover tomato plants with a protective covering is in the late afternoon or early evening when temperatures begin to drop. This will allow the plants to retain the heat stored in the soil during the day to keep them warm during the night. The cover should be removed in the morning once temperatures start to rise, allowing sunlight to reach the plants and promote healthy growth.

Choosing the Right Cover:

Choosing the right cover material is crucial to protect tomato plants from cold temperatures. Plastic covers are the most effective at trapping heat and creating a mini greenhouse environment around the plants. Fabric covers are also effective, but not as efficient as plastic covers. The type of cover chosen should depend on the severity of the weather conditions and the amount of protection needed.

Conclusion:

Knowing what temperature tomato plants should be covered is essential to ensure the plants remain healthy and continue to produce a fruitful harvest. Covering tomato plants with plastic or fabric in the late afternoon or early evening when temperatures begin to drop can help to provide insulation against cold temperatures. Choosing the right cover material can also help in protecting the plants from temperature fluctuations effectively. Protecting tomato plants through proper coverings is a necessary step for every gardener who wants to ensure that their tomato plants reach their full potential.
