How to Cover Tomato Plants from Frost

Frost is a major concern for tomato growers as it can damage or even kill the plants. However, there are several ways to protect tomato plants from frost. In this article, we will discuss how to cover tomato plants from frost.

1. Use Blankets or Row Covers

One of the easiest ways to protect your tomato plants from frost is to cover them with blankets or row covers. These materials provide a layer of insulation that can help keep the plants warm. Place the blankets or row covers over the tomato plants before sunset to trap the heat from the soil. Secure the edges of the blankets or row covers with rocks or bricks to prevent them from blowing away. Remove the coverings during the day to allow sunlight and air to reach the plants.

2. Use Plastic Tarps

Another option to protect your tomato plants from frost is to use plastic tarps. These tarps provide a larger layer of protection compared to blankets or row covers. Pull the tarps over the tomato plants before sunset and secure the edges with rocks or bricks. Do not let the plastic touch the leaves or stems of the tomato plants, as it can damage them. Remove the tarps during the day to allow sunlight and air to reach the plants.

3. Use Hot Water Bottles or Christmas Lights

You can also use hot water bottles or Christmas lights to protect your tomato plants from frost. Hot water bottles release heat slowly, which can help keep the plants warm. Place the hot water bottles around the tomato plants before sunset and cover them with blankets or row covers. Christmas lights can also provide heat to the plants. Place the lights around or under the tomato plants before sunset and cover them with blankets or row covers. Do not leave the hot water bottles or Christmas lights on for too long, as they can overheat and damage the plants.

4. Use Mulch

Mulch is another effective way to protect your tomato plants from frost. Mulch acts as a layer of insulation, keeping the soil warm and the roots protected. Apply 2-3 inches of mulch around the base of the tomato plants. Use straw, dried leaves, or grass clippings as mulch. Remember to remove the mulch during the day to allow sunlight and air to reach the plants.

5. Choose Frost-Resistant Varieties

Finally, you can choose frost-resistant varieties of tomato plants to avoid the need for covering them. Frost-resistant varieties can withstand low temperatures without being damaged. Look for varieties labeled as “cold-tolerant” or “early season” that can mature before the first frost. Some popular frost-resistant tomato varieties include ‘Sub-Arctic Plenty,’ ‘Northern Exposure,’ and ‘Stupice.’

In conclusion, protecting your tomato plants from frost is crucial for a successful harvest. Blankets or row covers, plastic tarps, hot water bottles or Christmas lights, mulch, and frost-resistant varieties are all effective ways to cover tomato plants from frost. Choose the method that works best for you and remember to remove the coverings during the day to allow sunlight and air to reach the plants.
