Winterbor kale is a hardy, frost-resistant variety of kale that is known for its curled, blue-green leaves and its ability to thrive in cold weather conditions. This nutritious vegetable is a great addition to any home garden, and with the right care and attention, you can enjoy a bountiful harvest even in the coldest months of the year.
Understanding Winterbor Kale
Before we dive into the specifics of planting and spacing, it’s important to understand what makes Winterbor kale unique. This variety of kale, scientifically known as Brassica oleracea, is a member of the cabbage family. It’s known for its high nutritional value, including high levels of vitamins A, C, and K, as well as a good source of calcium and iron.
Winterbor kale is a biennial plant, meaning it completes its life cycle in two years. However, it’s usually grown as an annual for its edible leaves. The plant is cold-hardy and can survive temperatures as low as -10 degrees Fahrenheit, making it an excellent choice for winter gardening.
Characteristics of Winterbor Kale
Winterbor kale is characterized by its tall, upright growth habit, reaching heights of 24 to 36 inches. The leaves are deeply ruffled and have a vibrant blue-green color. The flavor of the leaves is sweet, especially after exposure to frost, which tends to sweeten the leaves.
Winterbor kale is a vigorous grower and can produce leaves for harvesting within 50 to 60 days after planting. The plant continues to produce leaves throughout the winter, providing a continuous supply of fresh greens.
Preparing the Soil for Planting
Like most vegetables, Winterbor kale thrives in well-drained, fertile soil. The soil pH should ideally be between 6.0 and 7.0, which is slightly acidic to neutral. You can test your soil’s pH using a soil test kit, which is available at most garden centers.
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), you can add sulfur to lower the pH. Both lime and sulfur are available at garden centers.
Adding Organic Matter
Adding organic matter to the soil can improve its fertility and drainage. Compost, well-rotted manure, or leaf mold are excellent sources of organic matter. According to the USDA, adding organic matter can also help to improve the soil’s ability to hold onto nutrients and water, which is beneficial for plant growth.
Before planting, work the organic matter into the top 6 to 8 inches of soil. This can be done using a garden fork or a rototiller.
Planting Winterbor Kale
Once your soil is prepared, you’re ready to plant your Winterbor kale. Here’s a step-by-step guide:
- Start by marking out your planting rows. The rows should be spaced 18 to 24 inches apart, which gives the plants plenty of room to grow.
- Within each row, make a hole for each plant. The holes should be spaced 12 to 18 inches apart. This spacing allows for good air circulation, which can help to prevent diseases.
- Place a kale seedling in each hole. The top of the root ball should be level with the soil surface.
- Backfill the hole with soil, firming it gently around the base of the plant.
- Water the plants thoroughly after planting.
According to the University of Minnesota Extension, kale can also be direct-seeded into the garden. To do this, sow the seeds 1/4 to 1/2 inch deep and thin the seedlings to the recommended spacing once they’re large enough to handle.
Caring for Winterbor Kale
With the right care, your Winterbor kale plants can thrive and produce a bountiful harvest. Here are some tips for caring for your kale:
- Watering: Kale needs consistent watering to grow well. Aim for about 1 to 1.5 inches of water per week, including rainfall. If the weather is dry, you may need to water more frequently.
- Fertilizing: Kale is a heavy feeder and may benefit from additional nutrients. A balanced vegetable garden fertilizer can be applied according to the package instructions.
- Weeding: Keep the area around your kale plants free of weeds, which can compete with the kale for nutrients and water.
- Pest control: Watch out for common pests like aphids and cabbage worms. If you notice any, they can be controlled with insecticidal soap or other organic pest control methods.
Harvesting Winterbor Kale
One of the great things about Winterbor kale is that you can start harvesting as soon as the leaves are large enough to eat. Simply cut the outer leaves at the base, leaving the center of the plant to continue growing. According to the Penn State Extension, harvesting in this way can extend the productive life of the plant.
Remember, the flavor of Winterbor kale improves after a frost, so don’t be in a hurry to harvest all of your kale before the cold weather arrives. In fact, you may find that your Winterbor kale is one of the last vegetables standing in your garden, providing fresh greens long after other crops have been harvested.
Conclusion
Planting Winterbor kale is a great way to extend your gardening season and enjoy fresh, nutritious greens throughout the winter. With the right preparation and care, this hardy vegetable can thrive in your garden. So why not give it a try? You might just find that Winterbor kale becomes a staple in your winter garden.
