How to Grow Dwarf Blue Curled Kale
Brassica oleracea var. acephala 'Dwarf Blue Curled'
Dwarf Blue Curled Kale is a hardy brassica prized for its deep blue-green leaves and compact growth habit. Gardeners grow this easy-care variety to add vibrant color and nutritional value to salads or cooked dishes throughout the cool growing season.
Starting Dwarf Blue Curled Kale: indoors or direct sow?
🌾 Sow directly in the garden — Dwarf Blue Curled Kale is not usually started indoors.
Sow seeds directly in the garden rather than starting indoors, placing them out 2 to 6 weeks before the last frost date.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.5. Sow seeds directly outdoors 2 to 6 weeks before your last spring frost date, as this cool-season crop tolerates light chilling. Press seeds into the soil surface or cover them lightly at a depth of about 1/4 inch. Germination typically occurs within 5 to 10 days under these conditions.
Space plants 8 to 12 inches apart to ensure good air circulation and healthy head formation. While this variety does not require trellising, keep the soil consistently moist with about one inch of water per week. Apply a layer of mulch around the base to retain moisture and suppress weeds, feeding lightly if growth slows.
Monitor for cabbage worms, aphids, flea beetles, and loopers; use row covers or hand-pick pests early. Prevent clubroot, black rot, and downy mildew by ensuring good drainage and avoiding overhead watering. Harvest outer leaves as needed starting at 55 to 75 days after sowing when heads are firm.
