Plant 2-3 Waltham 29 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.\u003c\/p\u003e\n\u003cp\u003eOrganic broccoli 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.\u003c\/p\u003e\n\u003ch3\u003eOrganic Waltham 29 Broccoli in the Vegetable Garden\u003c\/h3\u003e\n\u003cp\u003eBroccoli 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.\u003c\/p\u003e\n\u003ch3\u003eHarvesting Organic Waltham 29 Broccoli\u003c\/h3\u003e\n\u003cp\u003eMost 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.\u003c\/p\u003e\n\u003ch3\u003eAbout Organic Waltham 29 Broccoli Garden Seeds\u003c\/h3\u003e\n\u003cp\u003eBred by the University of Massachusetts, Waltham Field Station, Waltham, MA around 1950.Waltham 29 broccoli produces uniform high yields, good color, cold resistance, dwarf compact plant, and big side shoots.\u003c\/p\u003e\n\u003cp\u003ePopular at Farmers Markets.
