Waltham 29 is a fantastic compact variety that thrives in cold climates producing large, uniform, tasty broccoli heads that are fantastic at regrowing! It has strong side shoots and like other brassicas the entire plant and leaves are edible. This cultivar was developed at the University of Massachusetts in the 1950’s, making it perfectly adapted to colder climates. This is a great option for growing until until maturity or as micro-greens!

Germination/Growing Info:
Broccoli seeds grow best in cool weather, so starting the seeds indoors 5-6 weeks before the last expected frost will ensure a faster crop. Shortly before the last frost and when the seedlings reach about 6″ tall, plant them 1-2′ apart in rows 2-3′ apart. For direct sowing seeds, plant them 1″ deep and 3″ apart in full sun and rich soil, about 2-3 weeks before the last expected spring frost; germination can take place at temperatures as low as 40 degrees F. For fall planting, direct sow Broccoli seeds in late July or August. For companion planting benefits, plant broccoli with herbs, potatoes, or onions; avoid planting it with tomatoes or pole beans.

Growing: Keep the young plants watered and remove weeds. Mulch helps discourage weeds and regulate soil temperature, and several applications of fertilizer or compost may also be needed. If several nights of below freezing temperatures are expected, cover the plants. If they become top heavy as they grow, provide a stake for support.

Harvesting: Harvest the main head while it is still tight, and before the florets begin to turn yellow; cut at least 6″ of the stem. Side shoots will continue to develop along the stem, and can be harvested as well; the plant will keep producing as long as weather conditions are favorable.

Seed Saving: Allowing Broccoli to produce seed will take an entire growing season, and may require digging up the plants for the winter or mulching them well. Broccoli will cross pollinate with other members of the cabbage family such as cauliflower, and isolation of at least 1/4 a mile is recommended to prevent cross breeding. Once the flowers have bloomed and produced seed pods, let them dry and carefully remove them from the plant. Separate the seeds from the pods. Store Broccoli seeds in a dry, cool place for up to five years.
