Julong is a new premium giant‑fruit watermelon variety from Ouland. These watermelon seeds generate vigorous, robust vines with strong disease resistance and solid heavy‑cropping tolerance. Plants produce huge oval‑shaped melons covered with deep dark‑green rind. Fruits feature outstanding quality and large fruit size, well‑suited for home growing and commercial field production. This variety performs excellently under open‑field conditions. Full‑sun exposure is essential to support massive fruit development and sugar build‑up. Reserve ample space for long sprawling vines. Monitor melon pests and fungal diseases throughout growth. Reduce watering frequency as fruits near full maturity to boost sweetness. Reasonable fertilizer application encourages vigorous vine growth and impressive large‑fruit yields.
Planting Instructions Soil Preparation Select a full‑sun location with reliable drainage. Mix generous well‑rotted organic compost into loose fertile sandy‑loam soil. Avoid waterlogged planting areas.
Seed Pre‑treatment Choose plump intact seeds. Soak seeds in warm water for 4‑6 hours, air‑dry lightly before sowing to improve germination performance. 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 healthy 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 Provide sufficient water in vine growing stage, cut back watering when fruits ripen. Apply balanced fertilizer for vine growth, use potassium‑rich fertilizer at fruit‑setting phase. Remove weeds timely. Watch for melon insects and fungal infections. Harvest when stem tendrils dry and rind becomes dull for optimal flavor.
