“Waltham 29” Broccoli was developed in 1950.  It is a dwarf compact plant with a branching habit that grows to 45-61 cm (18-24”) high with a spread of 45-55 cm (18-20”) wide.  It is a reliable heirloom that produces a solid bluish green head that is 10-20 cm (4-8”) wide.  Harvest the main head while it is still tight and cut at least 15 cm (6”) of the stem.  Side shoots will grow into flower heads and will continue to develop along the stem as long as the weather remains favorable. Plants are cold resistant and are able to tolerate a light frost.


Growing Instructions:


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.
