Waltham 29 Broccoli (Brassica oleracea var. italica) is a reliable heirloom variety renowned for its robust heads, rich flavor, and high nutritional value. Developed in Waltham, Massachusetts, this cool-season crop produces compact, dark green heads with tightly packed florets. Known for its cold tolerance and ability to produce side shoots after the main head is harvested, Waltham 29 is a favorite among home gardeners and market growers alike. It’s perfect for steaming, roasting, stir-frying, and freezing.

Growing Instructions

Start Waltham 29 Broccoli seeds indoors 6–8 weeks before the last frost date. Sow seeds 1/4 inch deep in seed-starting mix, maintaining a temperature of 60–70°F. Transplant seedlings outdoors when they are 4–6 inches tall and the soil temperature has reached at least 50°F. Space plants 18–24 inches apart in rows 24–36 inches apart. Broccoli thrives in full sun but can tolerate partial shade, especially in warmer climates. Keep soil consistently moist and apply mulch to retain moisture and reduce weeds. Harvest the central head when it reaches 4–6 inches in diameter. Cut the main head with a sharp knife to encourage side shoots for extended harvesting.
