Siberian kale, a hardy and nutritious leafy green, is a wonderful addition to any home garden. With its high tolerance for cold weather, it’s an excellent choice for those living in cooler climates. But how exactly do you go about planting Siberian kale? What are the best patterns and spacing techniques to ensure a bountiful harvest? Let’s dive in and find out.
Understanding Siberian Kale
Before we delve into the specifics of planting, it’s important to understand what makes Siberian kale unique. This variety of kale, as the name suggests, originates from Siberia and is known for its ability to withstand freezing temperatures. In fact, according to the USDA, Siberian kale can survive in temperatures as low as -10 degrees Fahrenheit.
Siberian kale is also known for its nutritional value. It’s packed with vitamins A, C, and K, as well as a good source of calcium, iron, and fiber. This makes it a great choice for those looking to add more nutrient-dense foods to their diet.
Preparing the Soil
Like most plants, Siberian kale thrives in well-drained soil that’s rich in organic matter. According to the Oregon State University Extension Service, a soil pH between 6.0 and 7.0 is ideal for kale. You can test your soil’s pH using a home test kit or by sending a sample to a soil testing lab.
If your soil is too acidic (below 6.0), you can add lime to raise the pH. If it’s too alkaline (above 7.0), adding sulfur can help lower the pH. Both lime and sulfur are available at most garden centers.
Adding compost or well-rotted manure to your soil can also improve its fertility and drainage. This is especially important if your soil is heavy clay or sandy, as these soil types can benefit from the added organic matter.

When to Plant
Siberian kale is a cool-season crop, which means it grows best in cooler temperatures. According to the National Gardening Association, the best time to plant Siberian kale is in early spring or late summer for a fall harvest.
Keep in mind that Siberian kale can tolerate frost, but it doesn’t do well in hot weather. If you’re planting in the spring, be sure to get your seeds in the ground a few weeks before the last expected frost date. If you’re planting in the summer, aim for about 6-8 weeks before the first expected frost date.
How to Plant
- Start by preparing your garden bed. Remove any weeds or rocks, and rake the soil until it’s smooth.
- Next, make a shallow trench about 1/4 to 1/2 inch deep. You can use the edge of a hoe or a stick to do this.
- Place the kale seeds in the trench, spacing them about 1 to 2 inches apart.
- Cover the seeds with soil and gently pat it down.
- Water the area thoroughly. Keep the soil moist, but not waterlogged, as this can cause the seeds to rot.
- Once the seedlings emerge and have a couple of true leaves, thin them to a final spacing of 12 to 18 inches apart. This gives each plant plenty of room to grow.
Patterns and Spacing
When it comes to planting patterns and spacing for Siberian kale, there are a few different methods you can use. The traditional method is to plant in rows, with each plant spaced 12 to 18 inches apart and each row spaced 18 to 24 inches apart. This allows for easy access for weeding and harvesting.
Another method is square foot gardening, which involves dividing your garden bed into 1-foot squares and planting a certain number of plants in each square. According to the Mel Bartholomew Foundation, the creator of the square foot gardening method, you can plant one kale plant per square foot.
Finally, there’s the hexagonal or “close planting” method. This involves planting in a hexagonal pattern, which allows you to fit more plants in a given area. With this method, you can space your kale plants about 10 inches apart.
Caring for Your Siberian Kale
Once your Siberian kale is planted, it’s important to provide it with the proper care to ensure a healthy harvest. This includes regular watering, fertilizing, and pest control.
Water your kale regularly, keeping the soil consistently moist but not waterlogged. A layer of mulch around the plants can help retain moisture and suppress weeds.
Fertilize your kale about a month after planting, using a balanced vegetable garden fertilizer. Follow the package instructions for application rates.
Keep an eye out for pests like aphids and cabbage worms, which can damage your kale plants. If you notice any pests, you can use an organic insecticidal soap or neem oil to control them.
Harvesting Your Siberian Kale
Harvesting Siberian kale is a simple process. According to the University of Minnesota Extension, you can start harvesting when the leaves are about 8 to 10 inches long. Simply cut the outer leaves at the base of the plant, leaving the center leaves to continue growing. This allows you to harvest from the same plant multiple times throughout the season.
Remember, Siberian kale is a cold-hardy plant, and its flavor actually improves after a frost. So don’t be in a rush to harvest all your kale before the first frost of the season. Instead, leave some leaves on the plant and enjoy the sweet, nutty flavor of frost-kissed kale.
With these tips and techniques, you’ll be well on your way to growing a successful crop of Siberian kale. Happy gardening!
