Waltham 29, developed in Massachusetts in the 1950s, earns its keep with stout plants, tight domed central heads, and a steady flush of side shoots for weeks of picking. Flavor leans nutty-sweet—especially after a light frost—and you’re packing in vitamins C and K plus glucosinolates with every bowl. Start early for summer harvests or sow for fall to let the cold sweeten it; transplant into rich, well-drained soil and keep moisture even. Reliable, productive, tasty—this is the backyard standard for a reason.

How to Grow

Start broccoli seed indoors 5-7 weeks before your anticipated planting date. Optimum soil temperature for seed germination is 50-85 degrees. Harden off plants by exposing them to an increasing number of hours outdoors each day 1-2 weeks prior to transplanting time. Set transplants in the garden 2-4 weeks before average last spring frost. Direct seeding is only recommended for areas with a long, cool spring season that will allow full maturity before summer heat sets in. For a fall harvest, plant transplants about 70 days before average first frost. Broccoli can be successfully direct seeded for a fall harvest 90-100 days before average first frost date. Broccoli is vert frost tolerant.
