Kale Dwarf Blue Curled

Brassica oleracea 

Characteristics

Dwarf Blue Curled Kale is a compact, hardy variety of kale known for its deeply curled blue-green leaves. It’s an excellent choice for smaller gardens, containers, and cold climates, and is often grown for its ornamental appeal as well as its nutritional benefits. Like other types of kale, it thrives in cool weather, producing sweet, tender leaves that are packed with nutrients.  Kale is a heavy feeder. Apply a balanced fertilizer or compost before planting and again as the plants start to grow. This helps support healthy leaf development.  Mulch around the base of the Dwarf Blue Curled Kale plants to retain moisture, suppress weeds, and keep the soil temperature consistent. Keep the area around the plants weed-free to reduce competition for nutrients and water.

Culture

• Height: 12-18”  Width: 8-12″
• Sun Light: Full sun but can tolerate partial shade, especially in hotter climates. Aim for at least 4-6 hours of sunlight per day
• Soil: It grows best in well-drained, fertile soil with a pH of 6.0-7.5. Adding compost or well-rotted manure before planting helps improve soil fertility.
• Watering: Keep the soil consistently moist. Kale requires regular watering, particularly in dry periods, to keep the leaves tender and flavorful.
• Temperature: Dwarf Blue Curled Kale thrives in cooler temperatures. It can tolerate light frosts and even some cold weather, which can enhance its flavor.

Pest & Disease Management

• Cabbage Worms: These pests can chew holes in kale leaves. Use row covers to protect young plants or apply Bt (Bacillus thuringiensis) to control infestations.
• Aphids: Kale can attract aphids, especially in hot weather. Use insecticidal soap or a strong stream of water to remove them.
• Flea Beetles: These small beetles create tiny holes in the leaves. Floating row covers can help prevent infestations.
• Downy Mildew: Ensure good air circulation around the plants and avoid overhead watering to prevent fungal diseases.

Tips for Growth / Harvest

• Frost Sweetening: Let the plants experience light frosts to improve flavor and sweetness.
• Shade in Summer: If growing kale in warmer weather, provide some shade to prevent the leaves from becoming tough and bitter.
• Continuous Harvest: Harvest outer leaves regularly to keep the plant producing new growth.
• Dwarf Blue Curled Kale is extremely cold-hardy and can tolerate temperatures as low as 20°F (-6°C) or lower. It is one of the best vegetables for fall and winter gardening, and the leaves become sweeter after a frost.
• In some regions, it can overwinter and produce new growth in early spring.
