Kale Lacinato: Seed Specifications, Germination, and Growing Conditions

Plant Characteristics

The Lacinato kale differs from other kales in appearance as well as flavor.

• Lifecycle: Biennial plant (lives for two years), but typically grown as an annual for leaf production.
• Leaf Shape & Color: Long, strap-like leaves with a deeply puckered texture and a dark, bluish-green color.
• Height: Most plants are 18-36 inches (45-90 cm) in height with a central stalk.
• Flavor: Milder than curly kale, with a gentle, earthy flavor that subtly tastes of nuts and benefits from a frost.
• Bloom Season: If overwintered, Kale Dinosaur will produce small yellow flowers in its second year which are also edible.

Uses

Also known as Kale Dinosaur, this plant provides a lot in both edible and ornamental values to any garden and kitchen.

Culinary

• Salads: Young, tender leaves can be eaten raw in salads.
• Cooking: Slightly matured leaves are sautéed with garlic and olive oil, stewed in soups (such as the Italian Ribollita) or added in stir-fries.
• Snacks: Leaves can be baked into crispy kale chips.
• Juicing & Smoothies: Can be found in many green smoothies because of all the vitamins and minerals.

Ornamental: Lacinato kale creates architectural interest in planting beds with its unusual leaf texture and upright growth habit.

Nutritional: Loaded with vitamins, minerals and antioxidants to support bone health immunity and digestion. It is also rich in fiber and good for gut health.

Growing Conditions

Kale Lacinato is a great crop for gardeners with the right growing conditions; and easy to grow as well.

• Soil: Rich, well-drained garden soil with a pH of 6.0–7.5 works best, and adding compost further supports healthy growth.
• Watering: Moisture should be regular but not excessive, ranging from 1-1.5 inches of rain per week. Mulching also keeps the moisture levels at the required level.
• Light: Grow best in full sun (6 to 8 hours a day), but can also bear partial shade.
• Temperature: Best for cool weather in between 55°F–75°F (13°C–24°C). Frost enhances leaf sweetness.
• Spacing: Set plants 12-18 inches apart in rows of 18-24 inches.

Seed Morphology

Lacinato kale seeds are tiny and round, and they look identical to other Brassica seeds.

• Size: About 1–2 mm in diameter.
• Color: Dark brown to black.
• Shape: Smooth and spherical, aiding in even sowing.

Germination Requirements

Like most Brassicas, Kale Lacinato has straightforward germination needs.

• Temperature: Optimum germination temperature is 60°F–70°F (16°C–21°C).
• Watering: Seeds require uniform moisture levels in the soil to sprout well.
• Light: Seeds need to be sown with a light cover of soil so they germinate in the dark.
• Soil pH: Soil pH should be around 6 to 7 (Slightly acidic to neutral soil).
• Timeline: Seeds germinate within 5–10 days.

Seed Viability and Vigor

Good storage can maintain very high, long-term rates of germination.

• Germination Rate: Fresh seeds typically achieve 80–90% germination under ideal conditions.
• Viability Period: Seeds remain viable for 4–5 years when stored properly.

Vigor Testing: Older seed can be given a damp-paper-towel germination test by gardeners before planting.

Propagation and Sowing

Lacinato Kale is usually grown by seed, but can be rooted from cuttings as well. Selecting high-quality vegetable seeds ensures vigorous seedlings and strong growth.

• Indoor Sowing: Sow seeds indoors 4-6 weeks before the last frost. Once see 4–6 true leaves, transplant seedlings outdoors.
• Direct Sowing: May be direct sown outdoors 2–4 weeks before last frost.
• Planting Depth: Seeds should be sown 0.6–1.2 cm (¼–½ inch) deep into the soil
• Thinning: After seedlings have established correctly, thin them to their proper spacing for best development.
• Succession Planting: Keep sowing every 2 — 3 weeks throughout the growing season for best results.

Disease and Pest Resistance

Lacinato Kale is hardy but still susceptible to common Brassica pests and diseases.

• Aphids: Colonies of aphids can be found under leaves sucking the sap out of the plant. It can be controlled with insecticidal soap or ladybugs. 
• Cabbage Worms & Loopers: Green caterpillars that remove large pieces of leaf. Row covers and hand-picking can minimize the damage.
• Flea Beetles: Very small beetles that leave small holes in leaves. Floating row covers work great as prevention.
• Clubroot: A soilborne disease that results in stunted plants with swollen roots. Crop rotation is the best preventive measure.
• Downy Mildew: Prefers a damp wet environment. Increase air circulation and do not water from overhead to prevent the disease.

Using correct insect and disease control solutions helps protect your plants naturally.

Storage and Handling

Harvested Lacinato kale should be handled carefully to preserve freshness.

• Harvesting: Harvest leaves individually as people need them, by picking outer leaves allowing the rest of the plant to continue growing.
• Storage Temperature: Store in a refrigerator at 32°F–40°F (0°C–4°C).
• Humidity: High humidity (95%) helps maintain leaf crispness.
• Shelf Life: Fresh leaves last 5–7 days. For longer storage, blanch and freeze.
• Seed Storage: Seeds should be stored in cool, dark, and dry (around 40°F / 4°C with humidity around only 40%) conditions, where they will remain viable for up to five years.
