Introducing Waltham Broccoli, the University of Massachusetts' answer to delicious and cold-tolerant broccoli. Released in 1950. This compact and stocky plant grows to 20 inches tall, with dark blue-green heads and large crops of side shoots. Suitable for late summer and fall harvest, Waltham Broccoli can survive dry spells and even the increasing cold of fall maturity. 500 mg ~ 150 seeds

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.
