  • 🥦 Classic Garden Broccoli Variety: Waltham 29 Broccoli is a trusted cool-season vegetable known for producing large central heads followed by numerous tender side shoots that extend the harvest. The sturdy plants grow vigorously in garden beds and raised beds, giving home gardeners reliable broccoli production for fresh kitchen use throughout the growing season.
  • 🌞 Sun Requirements: Waltham 29 Broccoli thrives in full sun, producing the strongest plants and most consistent head development when grown in a bright garden location with at least 6–8 hours of direct sunlight each day.
  • 💧 Watering Needs: Maintain evenly moist soil for best growth. Broccoli prefers steady watering throughout the growing season to support strong plant development and full, dense heads. Consistent moisture helps encourage continued side shoot production after the main head is harvested.
  • 🌱 Germination & Planting: Start seeds indoors 6–8 weeks before the last expected frost or sow directly outdoors in early spring. Plant seeds about ¼ inch deep in well-drained soil and keep soil evenly moist during germination. Seedlings typically emerge within 5–10 days and can be transplanted once established.
