Waltham 29, bred in Massachusetts in the 1950s, makes sturdy plants with big central heads and loads of side shoots for extended harvests. Flavor is nutty‑sweet, especially after light frost. Broccoli brings vitamins C and K plus glucosinolates. Start early, transplant with rich soil and steady water, and keep cutting to encourage new shoots. It’s the backyard standard for a reason—reliable, productive, and tasty.

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.
