Improved New Hongbao is an upgraded high‑performance watermelon cultivar. These watermelon seeds produce vigorous, hardy vines with reliable field adaptability. Plants bear large oval‑shaped fruits covered with distinctive light‑green cracked rind. The bright‑red flesh is crisp, juicy and rich in sugar, delivering excellent eating quality and good market appeal. This improved version brings stable high yields under open‑field growing conditions. Full‑sun positions are required to support full fruit enlargement and sugar accumulation. Provide enough growing space for sprawling vines. Keep regular checks for common melon pests and fungal diseases. Cut down watering quantity when fruits approach ripening to boost sweetness. Rational fertilization promotes strong vine growth and consistent large‑fruit harvests.
Planting Instructions Soil Preparation Select a full‑sun plot with excellent drainage. Mix plenty of well‑rotted organic compost into loose fertile sandy‑loam soil. Avoid waterlogged ground.
Seed Pre‑treatment Choose plump intact seeds. Soak seeds in warm water for 4‑6 hours, air‑dry lightly before sowing for better germination. Cold stratification is not needed.
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 retain one vigorous 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 sufficiently during vine growth stage, reduce watering as fruits ripen. Apply balanced fertilizer for vine development, use potassium‑rich fertilizer at fruit‑setting stage. Remove weeds timely. Monitor melon pests and fungal infections. Harvest when stem tendrils dry and rind turns dull for optimum sweet flavor.
