How to Grow Rapini from Seed

Direct sow Rapini seeds outdoors in early spring as soon as the soil can be worked for a spring harvest, or sow in late summer (about 6–8 weeks before your first fall frost) for an exceptionally tender autumn crop.

Sow seeds approximately 6 mm (1/4 inch) deep and 2.5 cm (1 inch) apart in rows spaced 30–45 cm (12–18 inches) apart. When seedlings reach 5–7 cm (2–3 inches) tall, thin them to a final spacing of 10–15 cm (4–6 inches) apart to allow space for vigorous leaf and shoot growth.

Select a location in full sun to partial shade with fertile, well-draining soil enriched with organic matter. Water consistently to maintain steady growth and keep stems succulent and sweet.

Harvest whole plants or snip young shoot clusters with unopened flower buds when plants reach 20–25 cm (8–10 inches) tall, before flowers open, to encourage second-growth shoots.

Growing Rapini in Canada

Rapini is exceptionally well-suited to Canadian growing conditions, thriving during the cool, crisp shoulder seasons of early spring and late fall across all growing zones.

Succession sowing every two weeks from early spring through midsummer provides a continuous supply of fresh, flavorful greens from early summer straight through until hard autumn frosts.
