This richly flavored open-pollinated Broccoli variety is popular with home vegetable gardeners! Green Sprouting Calabrese Broccoli seeds grow quickly and produce 4" heads with abundant side shoots, which can be harvested after the main head has been cut. Maturity time is not uniform, resulting in an extended harvest for home vegetable gardens!
Growing Instructions :
Heirloom Calabrese Green Sprouting 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 these Heirloom Calabrese Green Sprouting broccoli seeds 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 the 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 topheavy as they grow, provide a stake for support.
Harvesting: Harvest the main head while it is still tight, and before the tiny buds begin to open; 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 in a dry, cool place for up to five years.
