Waltham 29 broccoli seeds were specifically developed to withstand the colder temperatures of the Pacific Northwest and East Coast. These broccoli plants grow to a height of about 20 inches and form blue-green, medium to large heads on long stalks, a rarity amongst modern hybrids.
Start seeds indoors 5 to 6 weeks before the last frost in your area. When the seedlings are about 6 inches in height, harden them off for a week by gradually introducing them to outdoor temps and light. Transplant them an inch or two apart in rows that are 2-3 feet apart. Broccoli seeds may germinate with temperatures as low as 40 F. If you wish to direct sow, plant seeds an inch deep and 3 inches apart in rich, well-draining soil, 2-3 weeks prior to the last frost for your area.
Direct sow Waltham 29 broccoli seeds in late summer for a fall crop.
Waltham 29 broccoli will be ready to harvest 50-60 days from transplanting when the heads are dark green and compact. Cut the main head off along with 6 inches (15 cm.) of the stem. This will encourage the plant to produce side shoots that can be harvested at a later time.
