Jing Long Bao No.7 is a professional F1 hybrid large‑fruit watermelon variety. These watermelon seeds produce vigorous vines with strong disease resistance. Plants yield big oval‑shaped melons featuring striking dark‑green stripes over light‑green rind, delivering excellent market appearance and reliable fruit quality. The flesh is thick, crisp and sweet, ideal for home harvest as well as commercial growing. This hybrid performs well under open‑field conditions. Full‑sun planting maximizes fruit size and sugar content. Provide enough space for sprawling vines. Monitor for common melon diseases and pests. Reduce watering as fruits ripen to improve sweetness. Targeted fertilizing supports robust vine growth and heavy large‑fruit yields.
Planting Instructions Soil Preparation Select a full‑sun location with excellent drainage. Mix generous 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 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 vigorous plant 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, limit water supply when fruits approach maturity for higher sugar levels. Apply balanced fertilizer for vine development, use potassium‑rich fertilizer at fruit‑setting stage. Remove weeds regularly. Watch for melon pests and fungal infections. Harvest when tendrils near fruit stem dry and rind turns dull for best flavor.
