What Temperature Should Tomato Plants Be Covered?

Tomatoes are one of the most popular and beloved fruits around the world, known for their versatile uses in salads, sandwiches, salsas, and sauces. Growing your own tomato plants can be a fun and rewarding experience, but it can also be a bit challenging if you're not familiar with the ideal temperatures for tomato growth. In this article, we'll be discussing what temperature tomato plants should be covered at to ensure their health and productivity.

Why Should You Cover Tomato Plants?

Tomato plants are known to be sensitive to temperature changes, especially when they're young and still developing. If the temperature drops too low, it can cause the plant's growth to slow down or even stop entirely, which can lead to stunted growth or death. On the other hand, if the temperature gets too high, it can cause the plant to dry out and wilt, which can be equally damaging. Covering tomato plants can provide protection against these extreme temperature fluctuations and help them thrive properly.

What Temperature Should Tomato Plants Be Covered?

The ideal temperature range for tomato growth is between 60°F (15.5°C) and 75°F (24°C), making them a warm-season crop. However, covering tomato plants can help them withstand temperatures a bit outside of this range, depending on the type of cover you use.

One of the most common types of covers is plastic sheeting, which creates a mini-greenhouse effect around the plants. This can be especially helpful if you live in a cooler climate, as it will retain more heat and prevent frost from settling on the plants. However, plastic sheeting should only be used in temperatures that range between 65°F (18°C) and 85°F (29.5°C), as it can create a sauna-like environment if the temperature gets too high, which can lead to diseases or death.

If you're looking for a more natural cover option, using row covers made of lightweight fabric can be a good choice. These covers allow air and moisture to pass through while still protecting the plants from cold or hot temperatures. Row covers are ideal for temperatures between 50°F (10°C) and 85°F (29.5°C).

When To Cover Tomato Plants?

Timing is crucial when it comes to covering tomato plants. If you cover them too early, it can lead to overheating, while covering them too late can leave them exposed to frost or cold damage. The best time to cover tomato plants is during the late afternoon or early evening when the temperature starts to drop. This will allow the cover to trap the heat that has been stored up during the day and keep the plants warm through the night.

Conclusion

Tomato plants are a great addition to any garden, but they do require a bit of attention and care to thrive. Covering them can be a simple and effective way to protect them from harsh temperature changes and help them reach their full potential. Remember to choose the right type of cover for your climate and to cover them at the right time to ensure their health and productivity.
