Authentic Xinong No.8 is a classic F1 hybrid large‑fruit watermelon variety. These watermelon seeds produce vigorous vines with outstanding disease resistance and strong heavy‑cropping tolerance. Plants yield large oval‑shaped fruits with striking dark‑green stripes over light‑green rind. The thick red flesh is crisp, juicy and high‑sugar, delivering stable commercial‑grade quality. This well‑known hybrid performs reliably under open‑field conditions. Full‑sun planting helps maximize fruit size and sugar content. Leave sufficient room for long spreading vines. Routinely check for common melon pests and fungal diseases. Reduce watering frequency as fruits reach maturity to enhance sweetness. Balanced plus potassium‑rich fertilization supports healthy vine growth and abundant large‑fruit harvests.
Planting Instructions Soil Preparation Select a full‑sun location with excellent drainage. Mix plenty of well‑rotted organic compost into loose fertile sandy‑loam soil. Avoid waterlogged soil.
Seed Pre‑treatment Select plump, undamaged seeds. Soak seeds in warm water for 4‑6 hours, air‑dry lightly before sowing to boost germination. Cold stratification is not required.
Sowing Method Sow in spring after all frost risk passes. Place 2‑3 seeds per hole, cover with 2‑3 cm fine soil. Plant spacing 120‑150 cm, row spacing 180‑220 cm. Thin seedlings and keep one robust seedling per hole.
Germination Condition Optimal germination temperature:22‑30°C. Seedlings emerge within 7‑12 days. Keep soil moderately moist, avoid over‑watering.
Daily Maintenance Water adequately during vine growth, cut back watering when fruits ripen. Apply balanced fertilizer for vine development, switch to potassium‑rich fertilizer at fruit‑setting stage. Clear weeds on time. Inspect for melon pests and fungal infections. Harvest when stem tendrils dry and rind turns dull for best sweet‑flavored red flesh.
