Written by the GrowByCity Editorial Team · Updated April 2026
2 min read

Hybrid of broccoli and Chinese broccoli. Hardy enough to withstand light frosts down to 0°C, broccolini performs best when daytime temperatures stay between 12°C and 22°C. Give it full sun (6-8 hours of direct light daily) and regular watering to keep soil consistently moist, and expect to harvest in roughly 50-65 days. A staple of kitchen gardens and allotments, it rewards even first-time growers with a generous harvest.

Expert Tips

Harvest main stem first, then side shoots. More heat-tolerant than broccoli. Can be planted 2-3 weeks before the last expected frost, giving it a head start on the growing season. Aim for about 2.5 cm of water per week, adjusting for rainfall. Organic mulch around the base helps maintain even moisture.

  • 🌱 Broccolini needs at least 6-8 hours of direct sunlight daily for optimal growth.

Step-by-Step Growing Guide

Broccolini (Asparation — a trademark cross of Brassica oleracea and B. alboglabra) thrives in cool weather with fertile, well-drained soil and a pH of 6.0–7.0. Prepare beds with generous compost — broccolini is a heavy nitrogen feeder. Start seeds indoors 4–6 weeks before transplant, or direct sow outdoors when soil temperature is 45–85°F. Transplant 12–18 inches apart in rows 18–24 inches apart. Plant at the same depth as the seedling cell. Water consistently, 1–1.5 inches per week, as moisture stress causes bolting. Apply a high-nitrogen fertilizer every 3–4 weeks throughout the growing season. Unlike regular broccoli, broccolini does not produce a large central head — instead, it continuously produces slender stems topped with small florets over many weeks. Harvest the central stem when 8–10 inches long and florets are tight; side shoots will continue to emerge from the same plant for weeks. Spring and fall plantings outperform summer plantings significantly.

Common Pests & Problems

Cabbage worms (imported cabbageworm, Pieris rapae caterpillars) are the primary broccolini pest — pale green caterpillars blend perfectly with the foliage and cause ragged feeding damage. Apply Bt (Bacillus thuringiensis) as soon as adult white butterflies appear hovering over the plants, before eggs hatch. Aphids colonize the undersides of leaves and particularly cluster inside developing florets where they are very difficult to remove — use a strong jet of water and treat with insecticidal soap. Alternaria leaf spot causes dark brown circular lesions with concentric rings — ensure good airflow, avoid wetting foliage, and treat with copper fungicide. Club root causes distorted, swollen roots and yellowing foliage — raise soil pH above 7.2 with lime and rotate crops on a 4-year cycle.

Harvest & Storage

Harvest broccolini stems when they are 8–10 inches long, the florets are tightly closed and deep green, and before any yellowing begins. Use a sharp knife to cut just above a leaf node to encourage additional lateral shoot development. Harvest every 3–5 days during peak production. Fresh broccolini keeps for 5–7 days refrigerated in a perforated plastic bag. For longer storage, blanch in boiling water for 2 minutes, plunge into ice water, dry, and freeze in single layers; frozen broccolini retains quality for up to 1 year.

Popular Varieties

True broccolini is sold under the Asparation brand name and is a proprietary hybrid — seed is not generally available to home gardeners, making transplants from nurseries the primary source. 'Happy Rich' is a widely available open-pollinated type bred in Japan that closely resembles branded broccolini with profuse, thin stems and small florets. 'Di Cicco' is a traditional Italian sprouting broccoli (not true broccolini) that produces multiple small heads after the central head is cut — functionally similar in harvest style. 'Purple Sprouting' is a British heirloom sprouting broccoli overwintered for harvest in late winter or early spring, with the same continuous-harvest habit as broccolini.

When should I plant broccolini in my city?
