The Story
Ornamental Kale is a cultivar of Brassica oleracea, the same species that includes edible cabbage, broccoli, and cauliflower. Its origins can be traced back to the Mediterranean region, where wild cabbage varieties have been cultivated for centuries. While its edible relatives were selected for their culinary value, Ornamental Kale was specifically bred for its aesthetic appeal.
The plant gained popularity as an ornamental in Europe and Asia before making its way to North America. Its ability to withstand cold temperatures made it a valuable addition to gardens in regions with harsh winters. Today, Ornamental Kale is widely cultivated around the world and is a staple in fall and winter gardens, adding a touch of color when most other plants have gone dormant. It is often associated with autumn festivals and seasonal displays.
Complete Care Guide
Ornamental Kale thrives in cool weather and prefers full sun to partial shade. Plant it in well-draining soil that is rich in organic matter. Water regularly, especially during dry spells, but avoid overwatering, which can lead to root rot. Fertilize every 2-3 weeks with a balanced fertilizer during the growing season to promote vibrant colors. Deadhead any yellowing or damaged leaves to maintain its appearance. Protect from pests such as aphids and cabbage worms. Ensure good air circulation to prevent fungal diseases. Monitor for signs of disease or pest infestation and treat promptly. Provide support if the plant becomes top-heavy. Adjust watering and fertilization based on weather conditions.
Light Requirements
Ornamental Kale needs at least 6 hours of direct sunlight per day to develop its best color. Insufficient light can result in leggy growth and dull foliage. When planting, choose a location that receives full sun, especially during the cooler months. In warmer climates, providing some afternoon shade can prevent the leaves from scorching. For container-grown Ornamental Kale, rotate the pot regularly to ensure even light exposure. If growing indoors, supplement with grow lights to provide adequate illumination. East-facing windows are generally suitable, but south-facing windows may require shading during the hottest part of the day.
Seasonal Care
Spring
Fertilize regularly to encourage growth. Monitor for pests and diseases. Provide adequate sunlight and water. Transplant seedlings outdoors after the last frost.
Summer
Provide shade during the hottest part of the day. Water regularly to prevent drying out. Monitor for pests and diseases. Deadhead any yellowing leaves.
Fall
Plant Ornamental Kale in the fall for winter color. Provide adequate sunlight and water. Fertilize regularly to encourage growth. Protect from frost if necessary.
Winter
Protect from extreme cold and snow. Reduce watering as the plant's growth slows down. Monitor for pests and diseases. Enjoy the vibrant colors in the winter landscape.
The Life of Your Ornamental Kale
Seedling / Juvenile
Begin with nutrient-rich soil and ample sunlight. Water gently to avoid disturbing the seedlings. Provide adequate spacing to ensure proper air circulation. Monitor for any signs of pests or diseases. Harden off seedlings before transplanting outdoors.
Adolescent
Continue regular watering and fertilizing with a balanced fertilizer. Provide support if the plant becomes top-heavy. Monitor for pests and diseases and treat promptly. Ensure adequate sunlight for optimal color development.
Mature
Maintain consistent watering and fertilization. Deadhead any yellowing or damaged leaves. Protect from extreme weather conditions. Enjoy the vibrant colors and unique texture of the mature plant.
Established
Reduce watering and fertilization as the plant begins to fade. Remove any spent flower stalks. Consider transplanting to a larger container if necessary. Monitor for pests and diseases and treat promptly.
Propagation Guide
Ornamental Kale is typically grown from seed, but it can also be propagated through stem cuttings, although this is less common. To propagate from stem cuttings, take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide indirect light until roots develop.
Division is not a practical method for Ornamental Kale. Keiki production is not applicable to Ornamental Kale as it does not produce keikis.
Expert Knowledge
To maximize the color intensity of Ornamental Kale, expose it to cooler temperatures. The vibrant hues deepen as the weather gets colder. Avoid over-fertilizing, as this can lead to excessive green growth and reduce the intensity of the colored leaves. Ornamental Kale is relatively deer-resistant, making it a good choice for gardens prone to deer browsing. Consider planting Ornamental Kale in mass plantings for a dramatic visual impact.
Troubleshooting
Yellow leaves
Yellow leaves may indicate overwatering, nutrient deficiency, or pest infestation. Adjust watering habits and fertilize with a balanced fertilizer. Inspect for pests and treat accordingly.
Brown leaf edges
Brown edges can be caused by dry air, inconsistent watering, or fertilizer burn. Increase humidity, adjust watering habits, and reduce fertilizer concentration.
Drooping leaves
Drooping leaves may indicate underwatering, root rot, or extreme heat. Adjust watering habits, check for root rot, and provide shade during hot weather.
Root rot
Root rot is caused by overwatering and poor drainage. Improve drainage by using well-draining soil and avoiding overwatering. Treat with a fungicide if necessary.
Pests
Common pests include aphids, cabbage worms, and slugs. Inspect regularly and treat with insecticidal soap, neem oil, or handpick pests.
