Planting Tips for Success

• Sunlight: Full sun — at least 6 hours per day for best sprout development.
• Soil: Rich, well-drained, loamy soil with a pH of 6.0–7.5. Amend with compost before planting.
• Planting: 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.
• 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.
• Fertilizing: Apply a balanced nitrogen-rich fertilizer at transplant; side-dress with additional nitrogen 4 weeks after transplanting to support heavy sprout production.
• Support: Mound soil around the base of plants as they grow to prevent wind rock on these tall, top-heavy plants.
• 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.
