Brassica oleracea (botrytis group) 2 g packet sows 45 ft. Average varies by cultivar from ~5,000-8,000 seeds/oz.

Culture: Start broccoli indoors March–May for setting out May–July, or direct-seed in May or June for fall crop. Easier as a fall crop because many varieties perform poorly in hot summers. For better stands in dry conditions sow in trenches and keep irrigated. Broccoli dislikes extreme temperature and moisture fluctuations of the kind we have endured in recent seasons. Climate change is making it a challenge to grow even the more heat-tolerant varieties in the summer, while at the same time lengthening and making more temperate our New England falls, broadening growers’ windows of opportunity.

Nutrition and disclaimer: Broccoli contains significant levels of sulforaphane, a substance that helps detoxify carcinogens from the body. Some years back, research indicating that broccoli seed sprouts are higher in sulforaphane than the vegetable itself caused a run on open-pollinated broccoli seeds. The broccoli seed we offer is not food grade and we cannot guarantee that it is fit for human consumption as sprouted seeds. We have no control over the conditions in which it is stored before it reaches us. Please contact your natural foods wholesaler or retailer for sprouting seed.


Culture: Hardy. Require warm temperatures to germinate, but need 60s during seedling stage for optimal growth; higher temperatures make seedlings leggy. Heavy feeders; for best growth, need regular moisture and 2–3' spacing. Have done well for us succeeding onions and garlic in beds. Cauliflower and broccoli are damaged by hard frosts, especially in spring. Days to maturity are from direct seeding. Subtract 20 days from date of transplanting.

Pests & diseases: See below for more details. Based on six years here in Woodchuck Heaven, broccoli and brussels sprouts seedlings are the preferred choice for groundhog gourmets. Young edamame is next, with beans, carrot and parsnip tops and sweet corn a distant third. Kaidog kept me groundhog-free for over a decade in Maine, but did not make the move here. Gene uses Havahart traps.
