6 Best Types of Kale for Cold Climates

Kale is a typical green. It thrives in cool temps, and usually stops producing its best flavors once the weather turns hot.

Many kale types thrive in cold weather. We share our favorites: https://gardenerspath.com/plants/vegetables/best-kale-cold-climates/

Gardeners who want the largest possible greens harvest know that a spring and fall planting can optimize the best climate and create delicious, mild-tasting leaves without the plant bolting.

But what about when it turns bitter cold?

Certain varieties were meant to flourish when the first cold snap hits in the fall.

Developed for regions of the world where the growing seasons are shorter and more extreme, these cold-weather kales offer the best outcome for northern growing zones.

They give home growers a few more weeks to harvest fresh leaves, and get more greens into their fall and winter diets. As home growers, this is something that all of us can get behind!

6 Best Cold Weather Breeds

1. Lacinato (Dinosaur)

This bumpy, rough, and dark green cultivar is a champion of cold-weather varieties. Its leaves become sweeter and more pleasant after the first hard frost.

The Best Time to Plant

While winter kales do best in cold weather, they are appropriate to enjoy at any time.

Spring gardeners favor their flavor and are certain to use up most of their crops before the scorching sunny days in July and August. But most winter seeds are planted in the fall.

Once the final squash has been picked from the garden, many kale aficionados start work on their new rows.

They plant them where previous plants were grown, or start a “winter only” plot that can be protected more easily from extreme freezes.

Proper Care for Winter Gardens

Just because a kale is categorized as “wintry weather resistant” doesn’t mean you can just let them languish during the freeze. Extra steps should be taken to keep them protected against the harshest elements.

All kale types can benefit from these additional winter care steps:

1. Keep Warm

Once the first light frost of the season is forecast, cover the plants completely with straw.

If you prefer a more permanent structure, row covers or a small hoop house made from PVC and plastic sheeting will work as well.

A Note on Overheating

Any hoop or greenhouse has the potential to overheat the plants. Keep an eye on plants to prevent them from cooking underneath the plastic!

A good design will allow you to roll back the sheeting when needed, to allow proper ventilation.

2. Track Temps

Kale can be kept in the ground until soil temperatures reach 20°F. Continue to harvest as needed to encourage the plant to produce.

3. Fertilize, Feed, or Compost

When the ground freezes, you can choose to keep the plant in the ground to become nutritious matter for next year, or pull it up to feed to livestock or place in compost.

Enjoy Leafy Greens Through Colder Seasons

Winter weather growing is only possible in winter weather. Makes sense, right?

States with seasons that are extremely hot may find that they have fewer spring and summer weeks to grow their kales.

By planting in late fall for a winter harvest, however, any of these hearty cold-weather breeds will offer a second chance!
