Are Radishes Cold Hardy? Let's take a look, and see.

Radishes are a cool weather crop and can tolerate temperatures as low as 32 degrees Fahrenheit.

In general, radishes prefer a slightly acidic soil with a pH between 6.0 and 6.8.

How Cold Can Kale Tolerate

Kale is a highly nutritious leafy green vegetable that belongs to the cabbage family. It is one of the most popular vegetables in the world and is grown in many countries. Kale can be eaten raw or cooked, and its nutritional value remains high even when it is cooked.

Kale is a cool weather crop and can tolerate frost. In fact, kale actually becomes sweeter after a frost. For this reason, kale can be planted in early spring or late fall in most areas of the country.

However, if you live in an area with very cold winters, you may need to start your kale indoors so that it has a chance to grow before the frost hits. When growing kale outdoors, make sure to plant it in an area that gets full sun and has well-drained soil. Kale plants should be spaced about 18 inches apart, and they will need to be watered regularly during the growing season.

After about 2 months, your kale should be ready to harvest!

Do Radishes Need to Be Covered for Frost?

It’s that time of year again when gardeners start to think about protecting their plants from frost. One common question is whether or not radishes need to be covered for frost. The answer is yes, radishes do need to be covered for frost.

This is because radishes are a cool weather crop and can be damaged by even a light frost. If you live in an area with mild winters, you can probably get away with covering your radishes on nights when the temperature is expected to dip below freezing. However, if you live in an area with colder winters, you’ll need to take extra precautions and cover your radishes every night until the last danger of frost has passed.

There are a variety of ways that you can cover your radishes for protection from frost. One option is to use a floating row cover, which is a lightweight fabric that allows sunlight and water through but protects against frosts and pests. Another option is to place a layer of straw or mulch over the top of your plants.

Whatever method you choose, make sure that the material used extends all the way to the ground so that it forms a barrier against the cold air. With just a little bit of effort, you can keep your radishes safe from Frost damage and enjoy them all season long!

What Temp Kills Radishes?

If you’re looking to kill radishes, the best bet is to aim for a temperature of around -10°F. This will ensure that the radishes are killed outright, rather than simply damaged. Of course, temperatures this low can be difficult to achieve and maintain, so it’s important to plan ahead if you’re hoping to use this method.

Can I Grow Radishes in the Winter?

Radishes are a root vegetable that can be grown in the winter. They are a cool weather crop and can tolerate frost. Radishes grow best in full sun but will also do well in partial shade.

The soil should be loose and well-drained with a pH of 6.0 to 7.0. Radishes can be direct seeded or started indoors and then transplanted outdoors.

What Temperature Can Radish Seedlings Tolerate?

Radish seedlings are pretty hardy and can tolerate a wide range of temperatures, from hot to cold. They’ll do best in temperatures between 60-70 degrees Fahrenheit, but can also survive in colder or hotter temps for short periods of time.

Just be sure to transplant them outdoors before it gets too hot or cold!


Radishes are a hardy vegetable that can withstand cold temperatures. They can be planted in the spring as soon as the ground can be worked, and they will continue to produce through the fall. In fact, radishes actually get sweeter after a few light frosts.

If you live in an area with very cold winters, you can still enjoy fresh radishes by planting them in the fall and storing them in a root cellar over winter.
