Growing Instructions

• When to Plant: Sow directly in early spring, about 3 weeks before the last frost; a fall sowing works well in temperate climates.
• Soil: Fertile soil with a pH around 6.0–7.5 and plenty of organic matter.
• Sunlight: Full sun for the strongest color and growth.
• Watering: Water evenly and regularly; fast, well-watered growth keeps the flavor milder and avoids bitterness.
• Spacing: Sow 1/4 inch deep and thin seedlings to about 12 inches apart for full-sized plants.
• Germination: Seedlings emerge in 4–10 days at 68–75°F.
• Harvest: Cut individual outer leaves at any stage, taking no more than a third of the plant at a time for a continued harvest; leaves turn tough and overly pungent after flowering.
• Tips: Sow every two weeks for a steady supply; pinch off flower stalks early to prolong leaf production.
