Tomatoes are a perfect garden subject and a very easy subject to growing. So it is no wonder they are a favorite for home gardeners. But the real question is: can tomato plants survive frost? One of the most important factors in growing tomatoes successfully is to avoid frost. Winter brings a long season of cold weather and freezing temperatures. It’s the single worst time of year to plant your tomatoes.

Your tomato seedlings don’t have the protection of soil or warmth to help them grow, and they can be damaged by even the slightest chill. When temperatures drop to freezing, your tomato plants won’t stay alive. To keep your tomatoes from being killed off by the cold, here are a few things you can do in the garden to protect them against frost.

Tomato Plants’ Response To Frost

The best way to protect your plants is to keep them in an area where they will receive plenty of sunshine, such as a greenhouse or patio area. If you live somewhere where temperatures are very cold during the winter months, you should put your plants inside where they will get extra light and heat. If you do this, you can still harvest tomatoes when they are ready to pick.

If you’re unable to do this, you can purchase plant covers, tunnel row covers, or even use blankets or sheets to prevent your tomatoes from being damaged by frost. All of these options can help your tomato plants withstand the colder, winter months.

If your plants have been damaged by frost, you can use a homemade solution to try to heal them. You can use a mix of 1 part ammonia and 2 parts water. You can spray this solution on the leaves to help the plant’s cells open up again and absorb more sunlight. You can also use a mixture of 10 parts water and one part vinegar for a similar effect. You may want to apply the solutions as soon as possible. The sooner you treat them, the more likely the results will be good.

If you are planning to grow tomatoes in a cold climate, you should consider buying some tomato cages. These are helpful because they allow you to keep your plants off the ground. They make it possible for you to harvest your tomatoes while they are still small.
