Tomato plants are a staple in most UK gardens, but they are also delicate and need protection from harsh weather conditions, especially at night. Covering tomato plants at night is crucial for their continued growth and to ensure maximum yield when it is finally time to harvest. In this article, we will discuss when to cover tomato plants at night in the UK and how to do it effectively.

Why Cover Tomato Plants at Night in the UK?

Tomato plants, like most vegetables, grow best in warm temperatures. However, the UK weather can be unpredictable, and temperatures can drop significantly at night. This sudden drop in temperature can be harmful to the plant, causing it to wilt, and even die. Covering tomato plants at night helps to keep the plant warm and protect it from cold weather conditions, ensuring that it continues to grow and produce healthy fruits.

When to Cover Tomato Plants at Night in the UK?

The best time to cover tomato plants at night is when the temperature drops below 10°C. At this temperature, the plant may start to show signs of stress, such as wilting or yellowing leaves. It is essential to cover the plant before this happens, so the plant is protected from the cold weather. However, covering the plant too early can also have adverse effects, such as overheating the plant, causing more harm than good.

How to Cover Tomato Plants at Night in the UK?

There are several ways to cover tomato plants at night in the UK, including using frost blankets, cloths, and even polythene covers. Frost blankets are the most popular and effective method to protect tomato plants from cold nights. These blankets are made from breathable materials that allow air to circulate while keeping the plant warm. They also protect the plant from pests and harsh weather conditions. In contrast, cloths and polythene covers can suffocate the plant, causing it to overheat or even die.

To use a frost blanket, drape it over the plant, making sure to secure it tightly with pegs or clips. You can also use a tomato cage to support the blanket and prevent it from touching the plant. Make sure to remove the blanket in the morning when the weather warms up to prevent the plant from overheating or attracting pests.
