Bullet Points:

• Thick, Sweet & Juicy Stalks: The defining feature of Gai Lan is its fleshy, tender stalks. They are naturally sweet and incredibly crisp, offering a wonderful bite in stir-fries.
  
• Authentic Asian Culinary Gem: A staple of Cantonese cuisine! Classic dishes include "Gai Lan with Oyster Sauce" and quick garlic stir-fries. It's a gourmet vegetable that shines in the kitchen.
  
• Continuous Harvest (Cut & Come Again): Harvest the main central stalk, and the plant will quickly push out multiple new side shoots (lateral stems), giving you 3 to 4 harvests from a single planting!
  
• Fast-Growing & Cold-Hardy: Thrives in the cool temperatures of spring and fall. It tolerates light frosts exceptionally well, extending your gardening season.
  
• Nutrient-Dense Superfood: Packed with vitamins A, C, K, calcium, and iron. A delicious and healthy way to incorporate leafy greens into your family's diet.
  
• Versatile for Various Gardens: Its upright growth habit makes it perfect for dense garden rows, raised vegetable beds, and even large containers on a sunny patio.
  

Product Details:

• Genus: Brassica
• Species: Brassica oleracea (Alboglabra Group)
  
• Hardiness Zone: USDA Zones 4 – 11 (Hardy to frost, survives down to 25°F).
  
• Days to Maturity: 50 - 60 days (For main central stalks).
  
• Days to Germination: 5 to 8 days (Optimal soil temp: 60°F - 75°F).
  
• Seeding Depth: ¼ to ½ inch (0.6 - 1.2 cm).
• Row Spacing: 12 - 18 inches (30 - 45 cm).
  
• Plant Height: 16 – 24 inches (40 - 60 cm) upright before harvest.
  
• Growth Habit: Upright, leafy stalk. Features thick, succulent pale-green stems, broad leaves, and small, tight green flower buds at the apex. Produces continuous side shoots after the main central harvest.
  
• Soil Preference: Loose, fertile, well-draining loam rich in organic matter. pH 6.0 – 7.5.
  
• Temperature Preference:  Cool weather. Best performance at 55°F - 70°F (12°C - 21°C). Will bolt quickly in temperatures over 80°F.
  
• Light Preference: Full Sun (minimum 6 hours) to Partial Shade.

How to Plant & Grow:

• Site Preparation: Gai Lan thrives in full sun to partial shade. Prepare a garden bed with deep, loose, and fertile soil. Work 3 inches of aged compost into the top 6-8 inches of soil to ensure rapid growth and thick stems.
  
• Sowing: Direct sow seeds outdoors in early spring (4-6 weeks before the last frost) or in late summer for a fall crop. Plant seeds ¼ to ½ inch (0.6 - 1.2 cm) deep and cover lightly with fine soil. Keep the bed consistently moist until germination (5-8 days).
• For Large Central Heads: Space seedlings 6 to 8 inches (15-20 cm) apart in rows spaced 12 to 18 inches (30-45 cm) apart.
• For Continuous Side-Shoot Harvest : Space plants 5 inches (12 cm) apart in rows spaced 12 inches (30 cm) apart.
• Square Foot Gardening: Plant 4 plants per 1-square-foot area for dense, multiple shoot harvests.
• Watering: Consistent moisture is essential for keeping the stalks tender. Provide about 1 inch (2.5 cm) of water per week. Dry soil will cause the stems to become woody and fibrous.

Harvesting: 

• Main Stem: When the central stalk reaches 8-10 inches tall and the flower buds are tight and green (before they open into white flowers), use a sharp knife or scissors to cut the main stem about 2 inches (5 cm) above the soil line.
• Side Shoots: Leave the lower leaves intact. The plant will rapidly produce new shoots from the side nodes. Keep cutting these smaller shoots as they appear for a continuous supply!
• Gardener's Tip: Gai Lan is a cool-weather champion. In hot summer weather (above 80°F), it will quickly bolt (open flowers and become slightly bitter). For the sweetest harvest, plant it in early spring or late summer for a fall harvest.

Planting Calendar:

• Early Spring Crop:
  Direct Sow: March to Early April (as soon as soil reaches 45°F+). 
  Harvest: May to June.
  
• Fall Crop (Highly Recommended for best sweetness):
  Direct Sow: Mid-August to Mid-September
  Harvest: October to November.
• Mild Winter Zones (USDA 9-11):
  Direct Sow: Can be sown from October to December for winter harvests. (Tolerates light frost down to 28°F).
