Plants yield attractive round‑shaped fruits with striking dark‑green broad stripes over light‑green rind. The dense bright‑red flesh is crisp, juicy and high‑sugar, delivering outstanding eating quality and great commercial value. This new‑king melon variety shows stable performance under open‑field growing conditions. Full‑sun planting supports maximum fruit size and sugar accumulation. Leave ample space for sprawling vines. Conduct regular inspections for common melon pests and fungal diseases. Reduce watering volume as fruits approach ripening to boost sweetness. Balanced and potassium‑focused fertilization promotes healthy vine growth and consistent high‑quality harvests.
Planting Instructions Soil Preparation Select a full‑sun plot with excellent drainage. Mix abundant well‑rotted organic compost into loose fertile sandy‑loam soil. Avoid water‑logged planting locations.
Seed Pre‑treatment Choose plump undamaged seeds. Soak seeds in warm water for 4‑6 hours, air‑dry lightly before sowing to raise germination rate. 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 retain one strong 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, decrease watering when fruits ripen. Apply balanced fertilizer for vine development, switch to potassium‑rich fertilizer at fruit‑setting stage. Clear weeds timely. Monitor melon pests and fungal infections. Harvest when stem tendrils dry and rind turns dull for optimum sweet‑flavored red flesh.
