85-90 days. Waltham 29 Broccoli Seeds. Brassica oleracea var. italica. Annual. Non-GMO. Developed at the University of Massachusetts Amherst's historic research farm, Waltham Field Station, heirloom Waltham 29 broccoli garden seeds have been cultivated to deliver higher yields, grow more uniform vegetable crops, with more repeat harvests. Native to the brisk New England chill, non-GMO Waltham 29 seeds grow a compact, cold-hardy and open-pollinated American staple for home gardens and Farmers" Markets. ~9,000 seeds/oz.
Broccoli is a cool weather full-sun crop able to be sown directly but, for earliest starts, begin indoors 6-8 weeks prior to final spring frost or in mid-summer about 3 months from autumn frost. Plant 2-3 seeds 1/2" deep per cell or 4-6" apart in the garden in organic, fertile, and well-drained soil with a pH of 6.0-7.0.
Seeds germinate in 3-14 days, thinning out best starts every 12-18" in the garden once true leaves establish. Broccoli heads grow fullest with full sun but, for warmer regions, plants will benefit from midsummer shade. For warmer grow zones, try a cultivar with a quicker harvest and maturity date to best accommodate for a shortened cool spring season.
Waltham 29 Broccoli in the Vegetable Garden
Broccoli is a timeless annual staple of the home garden found just as often growing in the garden bed as on the kitchen counter. Broccoli has always been a tolerant frost hardy favorite, but is currently in its renaissance as a vitamin-rich crop popularly used in indoor gardening such as microgreens, sprouts, and hydroponics. Like other annual Brassicas such as cabbage, kale, and cauliflower, broccoli requires very similar growing conditions with similar harvest windows.
Harvesting Waltham 29 Broccoli
Most varieties of broccoli are ready to harvest in about 85 days from sowing. Using a small knife, remove the main head above the smaller florets once reaching a diameter of about 5-6", allowing secondary side shoots to continue maturing for harvest. Heads will taste bitter if no longer compact and have begun to flower. Like other Brassicas, the entire broccoli plant is harvestable and edible and even considered to taste best after a few light autumn frosts.
