Any grower chasing that classic, time-tested field watermelon will appreciate the reliable performance of Xinong No.8. This well-known variety has long been favored by farmers for its sturdy vines and heavy oblong fruits, marked with bold dark green stripes over a lighter green rind.
Slice one open and you’ll find thick, bright red flesh that’s crisp, juicy and packed with balanced sweetness. The rind offers decent thickness, helping the melons hold up well during transport and storage after harvest. Vigorous vines spread widely, and plenty of sunlight is essential to fully develop sugar content inside each fruit. Too much shade leads to bland taste and smaller melons. Take care to avoid waterlogged soil; watermelon roots rot quickly in soggy ground, especially during wet spells in early summer.
Growing Method Step 1: Choose an open, full-sun field with loose, sandy-loam soil and good drainage. Step 2: Sow seeds directly outdoors once soil warms up after frost risk passes, bury seeds 1–2cm deep. Step 3: Keep soil evenly moist for germination, maintain 22–30℃ for best sprout rate. Step 4: Leave 1.8–2.5m spacing between each plant, to give vines room to spread. Step 5: Add phosphorus and potassium fertilizer when female flowers appear to boost fruit swelling. Step 6: Water deeply while fruits grow, reduce watering 1–2 weeks before harvest to concentrate sweetness. Step 7: Harvest melons when the tendril near the fruit stem dries and the ground spot turns creamy yellow.
