Product Description

Scientific Name: Brassica oleracea, Botrytis Group

Sowing: For early planting, start seeds indoors with soil temperatures around 60°; plant about 1/4″ in soil; harden off transplants at around 4-5 weeks; transplant when 3-4 true leaves have shown; in cooler climates seeds can be direct-sown after the soil warms to 55°-60°;

Harvest: 65-80 days from transplant if started indoors; 75-100 days if direct sown in cooler climate; remove main head by cutting at 45° angle before, or as, head starts to separate from main stem (sign that broccoli is starting to flower); allow stock to continue to grow and produce “second heads” or side-shoots; Umpqua has particularly good side-shoot production;
