Planting Tips for Success

• When to Plant: Start indoors 6–8 weeks before last spring frost, or 12–14 weeks before first fall frost for a fall harvest. Transplant outdoors when seedlings are 4–6 inches tall.
• Sunlight: Full sun — at least 6–8 hours of direct sunlight daily for best sprout development.
• Soil: Rich, well-drained, loamy soil with a pH of 6.0–7.5. Amend with compost before planting.
• Planting Depth: Sow seeds ¼–½ inch deep indoors. Transplant seedlings outdoors when 4–6 weeks old.
• Spacing: Space plants 18–24 inches apart in rows 24–36 inches apart to ensure good air circulation.
• Watering: Water deeply and consistently; keep soil evenly moist. Mulch to retain moisture and regulate soil temperature.
• Support: Mound soil around the base of plants as they grow to prevent wind rock on these tall, top-heavy plants.
• Fertilizing: Apply a nitrogen-rich fertilizer at transplant; side-dress with additional nitrogen 4 weeks after transplanting to support heavy sprout production.
• Harvesting: Begin harvesting from the bottom of the stalk upward when sprouts reach 1–1.25 inches. Allow light frosts to sweeten flavor before final harvest. Plants can produce through multiple light frosts in Zones 7–9.
