Century Star No.8 is a high‑quality hybrid yellow‑heart cabbage. These yellow‑heart cabbage seeds produce compact plants with heavily crinkled dark‑green outer foliage and striking bright‑yellow inner heart. This variety features great cold tolerance, stable high yields and tender tasty leaves. Light frost can further improve its flavor profile. It is mainly suitable for late summer and autumn sowing. It grows well in garden plots and raised beds under full sunlight. Keep soil fertile and well‑drained. Monitor for typical brassica pests including flea beetles and cabbage caterpillars. Hot summer conditions will hinder proper heart formation and should be avoided. Consistent moisture and timely fertilizing help achieve full, well‑formed yellow‑heart heads.
Planting Instructions Soil Preparation Choose a full‑sun location. Mix plenty of well‑rotted organic compost into fertile loamy soil. Build raised beds where water accumulates easily to prevent root rot.
Seed Pre‑treatment Select plump healthy seeds. Soak in clean cool water for 2‑3 hours to speed germination, air‑dry slightly before sowing. Cold stratification is not required.
Sowing Method Sow from late summer to early autumn. Sow thinly and cover seeds with 0.8‑1 cm fine soil. Space plants 25‑30 cm apart, row spacing 35‑40 cm. Thin weaker seedlings after 2‑3 true leaves emerge.
Germination Condition Optimal germination temperature:15‑22°C. Seedlings emerge within 5‑10 days. Keep soil evenly moist, avoid waterlogging. High temperature suppresses germination.
Daily Maintenance Water evenly throughout leaf growth. Remove weeds on schedule. Inspect foliage for caterpillars and flea beetles. Apply nitrogen‑rich fertilizer in early growing phase. Harvest once the bright yellow inner heart is fully developed.
