Kale, specifically Red Ursa Kale, is a nutrient-dense, hearty, and versatile vegetable that can be grown in a variety of climates. It’s a favorite among gardeners for its beautiful, frilly leaves and its ability to withstand cooler temperatures. But how exactly do you plant Red Ursa Kale, and what are the best patterns and spacing techniques to ensure a bountiful harvest? Let’s delve into the details.
Understanding Red Ursa Kale
Before we get into the planting process, it’s important to understand what makes Red Ursa Kale unique. This variety of kale, known scientifically as Brassica oleracea, is a hybrid that combines the best traits of Russian and Siberian kales. It’s known for its beautiful, frilly leaves that are green with red veins, and its robust flavor that is both sweet and slightly spicy.
Red Ursa Kale is also known for its hardiness. According to the USDA, it can withstand temperatures as low as 20 degrees Fahrenheit, making it an excellent choice for fall and winter gardens. Plus, it’s packed with nutrients, including vitamins A, C, and K, as well as iron and calcium.
Preparing the Soil
Like all plants, Red Ursa Kale thrives in well-prepared soil. The Oregon State University Extension Service recommends a soil pH between 6.0 and 7.0 for optimal kale growth. You can test your soil’s pH with a home testing kit, or send a sample to a lab for more accurate results.
If your soil’s pH is too low (acidic), you can add lime to raise it. If it’s too high (alkaline), you can add sulfur to lower it. The amount you’ll need to add will depend on your soil’s current pH and texture.
Adding Organic Matter
Red Ursa Kale also benefits from rich, organic matter in the soil. This can come from compost, well-rotted manure, or a slow-release organic fertilizer. The University of Minnesota Extension suggests adding 2 to 3 inches of organic matter to the top 6 to 8 inches of soil.
This not only provides nutrients for the kale plants, but also improves soil structure, water retention, and beneficial microbial activity. Just be sure any manure is well-rotted to avoid burning the plants or introducing harmful pathogens.
Planting Red Ursa Kale
Now that your soil is prepared, it’s time to plant your Red Ursa Kale. This process involves several steps, which we’ll outline below.
- Choose the right time. Red Ursa Kale can be planted in the spring as soon as the soil can be worked, or in the late summer for a fall harvest. Keep in mind that kale tastes sweeter after a frost.
- Decide whether to start seeds indoors or direct sow in the garden. Starting seeds indoors 4 to 6 weeks before the last expected spring frost can give you a head start on the growing season. However, kale is also easy to direct sow.
- Plant the seeds. Whether you’re starting indoors or direct sowing, plant the seeds 1/2 inch deep. If you’re starting indoors, use a seed starting mix and keep the soil moist until the seeds germinate.
- Thin the seedlings. Once the seedlings have two sets of true leaves, thin them so they’re 12 to 18 inches apart. This gives each plant enough room to grow.
- Transplant seedlings. If you started your seeds indoors, transplant them to the garden after the last expected frost, spacing them 12 to 18 inches apart.
Patterns and Spacing
Proper spacing is crucial for healthy, productive Red Ursa Kale plants. As mentioned above, plants should be spaced 12 to 18 inches apart. This gives each plant enough room to grow and ensures good air circulation, which can help prevent disease.
As for patterns, there are several options. Some gardeners prefer traditional row planting, while others opt for square foot gardening or raised beds. The best pattern for you will depend on your garden’s size, your personal preference, and your gardening goals.
Row Planting
In a traditional row planting, Red Ursa Kale plants are spaced in straight lines, with 12 to 18 inches between each plant and 18 to 24 inches between each row. This pattern is easy to set up and makes weeding and harvesting straightforward.
Square Foot Gardening
In a square foot garden, the garden is divided into 1-foot squares, and each square is planted with a certain number of plants, depending on their size. For Red Ursa Kale, plant one plant per square foot. This pattern maximizes space and can result in a higher yield per square foot.
Raised Beds
Raised beds can be planted in rows or using the square foot method. The advantage of raised beds is that they provide good drainage, can be easier on the back, and can be filled with high-quality soil. Plus, they can be a good solution for gardens with poor soil or limited space.
Caring for Red Ursa Kale
Once your Red Ursa Kale is planted, it’s important to care for it properly to ensure a good harvest. This includes watering, fertilizing, and protecting the plants from pests and disease.
Red Ursa Kale prefers consistent moisture, so water regularly, especially during dry spells. A layer of mulch can help retain moisture and suppress weeds. As for fertilizing, a balanced organic fertilizer applied according to package instructions should provide all the nutrients your kale needs.
Common pests that affect kale include aphids, cabbage worms, and flea beetles. Handpicking, using row covers, and encouraging beneficial insects can help control these pests. If necessary, organic pesticides can be used. Diseases to watch out for include black rot, clubroot, and white rust. Practicing good sanitation, crop rotation, and proper spacing can help prevent these diseases.
Harvesting and Storing Red Ursa Kale
Red Ursa Kale can be harvested as soon as the leaves are large enough to eat, usually when they’re about the size of your hand. To harvest, simply cut the outer leaves, leaving the center of the plant to continue growing. This allows for a continuous harvest throughout the growing season.
After harvesting, Red Ursa Kale can be stored in the refrigerator for up to a week. For longer storage, it can be blanched and frozen, or even dehydrated. And of course, it can be used fresh in a variety of delicious recipes, from salads to stir-fries to smoothies.
With proper planning, preparation, and care, growing Red Ursa Kale can be a rewarding experience. Not only will you have a beautiful, productive plant in your garden, but you’ll also have a nutritious, delicious vegetable to enjoy in your meals. Happy gardening!
