Will 32 Degrees with Snow Kill Tomato Plants?

As a gardener, you may be wondering if your tomato plants will survive a cold snap, especially if it involves snow. In short, the answer is yes, 32 degrees Fahrenheit with snow can kill tomato plants. But there are ways to protect them from the freezing temperatures.

Understanding Cold Tolerance in Tomato Plants

Tomato plants are considered warm-season plants that thrive in temperatures between 70 to 80 degrees Fahrenheit. While they can tolerate temperatures as low as 50 degrees Fahrenheit, anything below that can cause damage to the plant's leaves, stems, and fruit.

It's important to note that not all tomato varieties have the same cold tolerance. Some are more resistant to cold than others. For instance, Siberian, Glacier, and Stupice are some of the hardiest tomato varieties that can tolerate frost and light freezes. Other varieties, such as Beefsteak and Brandywine, are not as cold-tolerant and may suffer more damage from low temperatures.

Protecting Tomato Plants from Low Temperatures

The good news is that there are several ways to protect your tomato plants from the cold weather. Here are some helpful tips:

1. Cover Tomato Plants

One of the most effective ways to protect tomato plants from cold is to cover them with a blanket or an old bedsheet. Make sure to secure the edges of the cover with rocks, bricks, or other heavy objects to prevent it from flying away in case of wind. You can also use commercial frost blankets or row covers that are specifically designed for plant protection.

2. Water Your Plants

Believe it or not, watering your plants can actually help protect them from frost damage. Water releases heat as it freezes, which can help increase the temperature around the plants. However, make sure to water your plants before the temperatures drop, so the water has time to soak into the soil and not freeze around the roots.

3. Use Mulch

Mulch is great for regulating soil temperature and protecting plants' roots. A layer of organic mulch, such as straw, pine needles, or leaves, can help insulate the soil and keep it from freezing. Just be sure not to pile it too high around the stem of the plant, as this can lead to stem rot.

Final Thoughts

In conclusion, 32 degrees with snow can indeed kill tomato plants, but with some extra care, you can protect them from low temperatures. Covering them with blankets, watering before the freeze, and using mulch can all help shield your plants from the cold. Remember to choose cold-tolerant varieties if you live in an area with frequent frosts, and always pay attention to weather reports to prepare your plants accordingly.
