Can Carrots Survive Frost?

Carrots are one of the most popular vegetables in the world, and they’re a hardy crop that can survive even the harshest winter weather. But if you live in a cold climate, you might be wondering: Can carrots survive frost? And how does freezing affect them?

This article will answer all your questions about how to keep your carrots safe and healthy during the winter months.

Can Carrots Survive Frost?

Carrots can survive frost, but they will not grow as well if the ground is frozen. Carrots do best when the soil temperature is between 50 and 55 degrees Fahrenheit (10 to 13 degrees Celsius). If it gets colder than that, the carrot seeds could freeze and die.

If you live in Florida or California where winters are milder. Chances are good that your vegetables will survive a light frost if you have planted the carrots early enough to mature before winter comes along and freezes them out of existence!

On the other hand, if you are growing carrots in an area with a short growing season, such as Colorado or Minnesota, you might want to consider protecting your seedlings somehow from any potential cold snaps.

How Tolerant Are Carrots To Cold Weather

Carrots are naturally hardy plants. They can withstand frost and cold weather quite well, but they do have their limits.

The most important factor in determining how tolerant your carrots are too cold is the variety of carrots you’re growing. Some varieties are more frost-tolerant than others, so if you choose a particular variety that’s known for being less tolerant of cool temperatures, you’ll need to be extra careful about protecting it from freezing weather.

Carrots generally tolerate temperatures down to about 15 degrees F before suffering any damage or dieback (15 degrees C). On average, carrot roots will start freezing at around 20 degrees F (-6 degrees C), but this varies depending on the type of soil in which they’re growing and whether they’ve been covered with mulch or other protection against exposure to colder temperatures.

How To Protect Your Carrots From Frost

To protect carrots from frost, you should:

  • Cover them with mulch. Mulch is an organic material like straw or hay that helps retain moisture when applied to the surface of the soil. Think about it as a blanket for your carrot plants!
  • Use a row cover over the bed after planting your crop but before the first frost date arrives in your area (October 15th). The row cover will prevent moisture from evaporating from under the plastic sheeting, which would otherwise cause damage to young seedlings during colder temperatures and overnight freezes.
  • Alternatively, you can use clear plastic sheeting under blankets or tarps on top of beds as long as there are no holes in these materials through which cold air could penetrate into ground-level plantings during nights with heavy dewfall conditions – this could lead to cold injury symptoms such as wilting away from central stems rather than at tips towards petioles (leaf stalks) where they may be more susceptible due to increased demand upon transpiration rates caused by high temperatures during daytime hours.

What Temperatures Will Kill Carrots?

Carrots can survive cold temperatures, but they won’t last for a long time.

There are several factors that affect the longevity of carrots in the garden: soil temperature, air temperature, and humidity.

Soil temperature is the most important factor for growing carrots. In general, it takes about 10°F (5°C) to kill most of the carrot plant’s root system. So if you’re planning on storing your carrots for a long time and you expect the soil temperature to drop below 10°F (5°C), it’s best to harvest them before that happens.

Air temperature affects how quickly your carrots will freeze, so if you want to keep them for a few months after harvest, make sure that their air temperatures stay above freezing during this time.

Humidity is important because it slows down how fast ice forms on top of your carrot plants’ roots—this is why frost-free areas can grow carrots year-round!

Can I overwinter carrots?

You can overwinter carrots by leaving them in the ground until the first hard frost. To protect your carrot plant from freezing temperatures, consider covering it with a cold frame or greenhouse.

A cold frame is basically a box that sits on top of the ground, while greenhouses are larger structures that provide protection from wind and rain as well as frost.

If you don’t have access to these tools, though—perhaps because you live in an apartment without access to a roof—you can dig up your carrots and store them indoors for use during the winter months. The best way to do this is by storing them in the sand at room temperature (around 65 degrees Fahrenheit) with plenty of ventilation so they don’t rot from moisture buildup inside their root cells!


Carrots can be a delicious addition to your garden, but they are not always easy to grow. If you have found that frost has damaged your carrots, try some of the above tips for protecting them from the cold.
