What to Cover Tomato Plants with When Frost

Frost is a concern for tomato plants, as they are relatively delicate and prone to damage when exposed to freezing temperatures. To protect your tomato plants from frost, it is important to cover them with the right material. In this article, we will discuss what to cover tomato plants with when frost is a risk.

When to Cover Tomato Plants

The decision to cover your tomato plants should be based on the weather forecast. If overnight temperatures are predicted to drop below 32°F (0°C), it is essential to cover your plants. However, if the forecast temperatures are going to be in the mid to high 30s, you may be able to skip covering your plants. It's important to monitor the forecast carefully to avoid damaging your tomato plants.

What to Cover Tomato Plants With

The material you use to cover your tomato plants should provide insulation and prevent frost from forming on the leaves. Here are some options:

1. Blankets or Sheets

You can use old blankets or sheets to cover your tomato plants. These materials don't provide much insulation, but they do help to prevent frost from forming on the leaves. Make sure the material you use doesn't touch the plant's leaves, as this can cause damage. Use stakes or other supports to hold the blankets or sheets in place.

2. Frost Cloths

Frost cloths are specially designed to protect plants from frost. They are made from lightweight fabrics that provide insulation without weighing down the plant. Frost cloths can be draped over tomato plants and secured with stakes or other supports. They allow air and moisture to circulate while providing protection from frost and wind.

3. Plastic Sheeting

Plastic sheeting can also be used to protect tomato plants from frost. This material is inexpensive and easy to find at most hardware stores. However, it is important to use caution when using plastic sheeting, as it can trap moisture and cause the leaves to freeze. To avoid this, only use plastic sheeting for short durations and remove it as soon as temperatures rise above freezing.

Tips for Covering Tomato Plants

Covering tomato plants is a simple process, but there are a few tips to keep in mind to ensure you protect your plants properly:

Choose the right material for your climate.

Don't let the material touch the plant's leaves.

Secure the fabric with stakes or other supports.

Remove the covering as soon as temperatures rise above freezing.

Final Thoughts

Covering tomato plants with the right material can protect them from frost and ensure a successful harvest. By following these tips and monitoring the weather forecast, you can protect your tomato plants from the damaging effects of freezing temperatures.
