Decorative kale, also known as ornamental kale or cabbage, has become a beloved addition to many gardens not just for its cold hardiness, but for its striking aesthetic appeal. With its vibrant, frilly leaves that come in an array of hues from deep purples to bright pinks and greens, this plant offers more than just winter interest; it provides year-round beauty if you know when to plant it.
Understanding the Growth Cycle of Decorative Kale
Before we dive into the optimal planting times, it’s crucial to understand the growth cycle of decorative kale:
- Early Growth: The plant starts with vibrant green foliage, setting the stage for its later transformation.
- Color Transformation: As the weather cools, the kale begins to showcase its true colors. This is when the foliage turns from green to a spectrum of purples, pinks, reds, and whites.
- Maturity: Decorative kale is typically ready for full display and harvest 70-95 days after planting, though this can vary by variety and growing conditions.
Optimal Planting Times
For Fall and Winter Color
The primary allure of planting decorative kale for many is to bring color to their gardens during the fall and winter months:
- Zone 7 and Above: Plant in late summer to early fall. A good rule of thumb is about 6-8 weeks before the first expected frost, allowing the kale to mature before temperatures drop significantly.
- Zone 6 and Below: Here, you can push this timeline slightly earlier to late summer. Kale planted at this time will benefit from the cooler nights, which enhance the foliage’s color development.
🌿 Note: Frost can enhance the kale's color but can also damage the outer leaves. Mulching around the plants can protect them from harsh winter conditions.
For Continuous Color
If you desire continuous color in your garden:
- Succession Planting: Start with a fall planting as mentioned above, then follow up with a late spring planting. This ensures a continuous display from late spring through winter.
- Direct Sowing: Alternatively, some gardeners opt to sow seeds directly into the garden in late spring or early summer. This approach allows the kale to reach maturity in time for fall color displays.
Steps to Planting Decorative Kale
Planting decorative kale effectively involves a few key steps:
- Choose the Right Variety: Varieties like ‘Redbor’, ‘Osaka’, or ‘Coral Queen’ offer different color transitions and frill patterns.
- Prepare the Soil: Decorative kale prefers well-draining, loamy soil. Enrich the soil with compost or a balanced fertilizer to provide necessary nutrients.
- Planting Time: Follow the guidelines based on your planting zone:
- Plant Spacing: Space plants about 12-18 inches apart to give them room to expand and showcase their beauty.
- Watering and Care: Water well after planting, keep soil moist but not waterlogged. Once established, reduce watering frequency but maintain consistent soil moisture.
| Planting Zone | Recommended Planting Time |
|---|---|
| Zone 7 and Above | Late Summer to Early Fall |
| Zone 6 and Below | Late Summer |
🌱 Note: Direct sunlight encourages the best color development in decorative kale, so ensure your planting location gets at least 6 hours of direct sunlight daily.
Integrating decorative kale into your garden not only adds visual interest but also serves as an educational experience, teaching you about the nuances of plant growth cycles and seasonal gardening. This plant can transform a garden from mere greenery into a kaleidoscope of color, especially when the weather turns cold.
In summary, decorative kale should be planted with consideration of the region's climate, the growth cycle of the plant, and the gardener's desire for continuous color or just for fall and winter displays. Whether you're seeking a temporary splash of color or a year-round addition to your garden, understanding when to plant decorative kale can lead to stunning garden displays that captivate all who see them. By following the steps outlined here, from selecting the right variety to understanding the optimal planting times, you can ensure that your decorative kale thrives and adds unparalleled beauty to your garden landscape.
