Xinyan Hybrid Crown is an F1 hybrid yellow‑heart cabbage (tatsoi‑type yellow heart cabbage). These yellow‑heart cabbage seeds produce compact plants with heavily crinkled dark‑green outer leaves and beautiful golden‑yellow inner heart. This variety features excellent cold tolerance, fine texture and delicious mild flavour. It performs outstandingly in cool‑season autumn planting. It grows well in vegetable plots, raised garden beds. Full sun promotes solid leaf‑head formation. Keep watch for brassica pests such as flea beetles and caterpillars. Maintain fertile, well‑drained soil with consistent moisture. Avoid high‑temperature growing conditions, heat will hurt head formation and taste quality.
Planting Instructions Soil Preparation Pick a full‑sun planting site. Mix abundant well‑rotted organic compost into fertile loamy soil. Build raised beds if rainwater tends to pool, to prevent root rot.
Seed Pre‑treatment Select plump intact seeds. Soak seeds in cool clean water for 2‑3 hours to accelerate germination, air‑dry lightly before sowing. Cold stratification is not needed.
Sowing Method Sow mainly in late summer‑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 weak seedlings after 2‑3 true leaves show up.
Germination Condition Optimal germination temperature:15‑22°C. Seedlings emerge in 5‑10 days. Keep soil evenly moist, prevent waterlogging. High temperature restricts germination.
Daily Maintenance Water evenly during leaf‑growing period. Weed on time, young seedlings compete poorly against weeds. Check leaves regularly for caterpillars and flea beetles. Apply nitrogen‑rich fertilizer in early growth stage. Harvest when inner yellow heart is fully developed.
