Early harvests of thick spears.

Spears are tender and sweet, developing a mustardy flavor as they mature. Although transplanting is recommended, it performs better direct-seeded and at tighter spacing than our other mini broccoli varieties (4–6″ in-row). Can be 1–2 weeks earlier than Happy Rich, but less heat tolerant and with a shorter harvest period. This Chinese specialty (also known as Kailaan or Chinese kale) can be sold loose or in bunches.

Size

Packet, 1,000 Seeds, 5,000 Seeds, 25,000 Seeds, 100,000 Seeds

SCIENTIFIC NAME

Brassica oleracea (unless otherwise indicated).

CULTURE

Prefers a well-drained, fertile soil high in organic matter with a pH of 6.0–7.5. Prefers a consistent supply of moisture throughout the growing season. Irrigate regularly for best results.

DISEASES AND INSECT PESTS

Prevent flea beetle damage by applying floating row cover at planting. Flea beetles can also be controlled with insecticides such as azadirachtin or pyrethrin. Cabbage worms can be controlled with Bacillus thuringiensis. Prevent disease with crop rotation and good sanitation.

TRANSPLANTING

Sow 2 seeds per cell in 72-cell plug flats, 3–4 seeds/in. in 20-row flats, or in outdoor beds ¼" deep. Seedlings should be ready to transplant in 3–4 weeks. If possible, keep soil temperature 75–80°F (24–27°C) until germination, then reduce air temperature to about 60°F (16°C). Ensure good air circulation and light. Transplant outdoors 6–12" apart for spring raab and 12–24" apart for sprouting broccoli in rows 18–36" apart.

DIRECT SEEDING

Sow 3 seeds per foot, ½" deep, rows 18–36" apart, thinning to one plant per foot.

COLD TREATMENT (VERNALIZATION)

Late-sprouting varieties require exposure to temperatures at or below 50°F (10°C) to induce budding. See individual varieties for duration of vernalization period.

PINCHING

For some varieties, side-shoot production can be increased by pinching the initial head as soon as it forms. See individual varieties for pinching recommendations.

HARVEST

Before flower buds open, cut stems of central head and side shoots. Stems 4–8" in length can be bunched for sale or sold loose. Harvest regularly to encourage continued production.

DAYS TO MATURITY

Sprouting broccoli: From transplant date to central head harvest, side shoots will follow. Spring raab: From direct seeding.

SIZED SEEDS

"Sized" seeds have been sorted so they are roughly the same size. This consistency allows for more accurate spacing with mechanical seeders and more even germination. Broccoli seeds are sized, except when noted in the product description.

SEED SPECS

Seeds/lb. 52,900–142,100 (Avg. 104,100)

PACKET

100 seeds, sows 50', unless otherwise noted.
