Di Cicco Broccoli is an old Italian Heirloom broccoli that dates back to 1890. It grows to an average height of 61-91 cm, (24-36") with a spread that is 30 cm (12") wide. It is an excellent choice for extended harvests for home gardeners. The plants yield a vigorous supply of 7-11 cm, (3-4") clusters of blue-green heads. After cutting the main head, more side shoots develop, producing many more small to medium-sized heads throughout the summer.
Start broccoli seeds indoors 6-8 weeks before the last frost date in your area, or direct sow seeds in early spring or late summer. Select a location that receives full sun, or partial shade in hotter climates. Sow seeds 1cm (½”) deep, spaced 5-10cm (2-4”) apart. Keep soil moist and cool to promote germination. Seeds should sprout in 5-10 days. Thin seedlings to 30-45cm (12-18”) apart when they are 5-7cm (2-3”) tall. Broccoli prefers well-drained soil that is rich in organic matter. Soil pH should be between 6.0 and 7.5. Fertilize with a balanced fertilizer before planting and again 3-4 weeks after transplanting. Keep soil consistently moist throughout the growing season. Harvest the broccoli heads when they are tight and firm before they start to yellow or open up.
