Direct Sowing: For direct sowing, plant ‘Waltham 29’ broccoli seeds outdoors in early spring, about 2-4 weeks before the last expected frost. Sow seeds ½ inch deep and 2-4 inches apart in rows spaced 24 inches apart. Germination usually occurs within 7-14 days. Broccoli thrives in well-drained, fertile soil rich in organic matter, so it’s crucial to keep the soil consistently moist through regular watering. Thin seedlings to about 12-18 inches apart once they are a few inches tall to allow for adequate growth. Expect to harvest in about 70-90 days.

Early Sowing for Seedlings: For an earlier harvest, sow ‘Waltham 29’ seeds indoors 6-8 weeks before the last expected frost. Plant seeds ½ inch deep in seed trays filled with quality potting mix, maintaining a temperature of 70°F – 75°F for optimal germination. Once seedlings develop a few true leaves and the risk of frost has passed, transplant them outdoors, spacing them 12-18 inches apart in rows. Water the transplants well after planting to ensure strong root establishment.

Harvesting: ‘Waltham 29’ broccoli is ready to harvest when the central head is tight and firm, typically around 70-90 days after sowing. Cut the main head with a sharp knife, taking care not to damage the surrounding leaves. After the main head is harvested, the plant will produce numerous side shoots, allowing for multiple harvests over several weeks. For the best flavor, harvest side shoots when they are young and tender.
