Best varieties of kale for cold climate growing?

Choosing the Right Kale Variety

When selecting kale varieties for cold climate growing, look for plants that are specifically bred for hardiness and can tolerate frost. These varieties will typically have a more compact growth habit, which makes them less susceptible to wind damage and easier to harvest. ‘Dwarf Blue Curled’ kale, for example, is a popular choice for cold climates due to its ability to withstand temperatures as low as 10°F (-12°C).

Planting and Growing Techniques

To ensure successful growth of kale in cold climates, plant the seeds 2-3 weeks before the last frost date. This will give the seedlings a head start on the season and allow them to mature before the first frost. Plant the seeds 2-3 inches apart and 1/4 inch deep, and water them regularly until they are established. Use row covers or other frost protection techniques to extend the growing season and protect the plants from extreme cold.

Tips for Year-Round Production

To achieve year-round production of kale in cold climates, consider using a cold frame or hoop house to extend the growing season. This will allow you to grow kale in the winter months when the soil is too cold for direct planting. You can also use succession planting techniques to ensure a continuous supply of fresh kale throughout the growing season. By planting small batches of kale every 1-2 weeks, you can have a steady supply of fresh greens from early spring to late fall.
