16.Planting tips:
Choose a plot with deep soil, good drainage and irrigation, and full sunlight. Plow the land in advance and apply adequate base fertilizer. Before sowing, pre‑germinate the seeds; once they sprout, place them in nutrient cups. This ensures vigorous growth and rapid germination. Transplant the seedlings promptly after they are well established. Watermelons are heavy feeders, so fertilize in time during later management and prune vines according to specific growth conditions
