Seed selection: If you want a high yield of watermelon, you must choose plump, mature and strong watermelon seeds. After selecting them, soak them in warm water at 55 degrees Celsius, which has a bactericidal effect. Then disinfect it with a small amount of benomyl solution and then air dry it.

Germination: Watermelon needs to be soaked to germinate before sowing. First soak the seeds in warm water and wash them, then wrap them in moistened, tight gauze and place them in a sunny environment for two or three hours. Then cover it with a layer of moisture and place it in a constant temperature box at 30 degrees Celsius. After waiting for 36 hours, the seeds will germinate.

Soil preparation: The soil should be well drained and breathable, and rich in humus. You can add a small amount of compound liquid fertilizer and mix well. Then water it adequately to keep the soil moist.

Sowing: Place the seedlings in the nutrient soil, spread the seeds flat on the soil with the bud end facing down, and then cover them with a layer of soil about two centimeters thick. Then cover the flower pot with a layer of plastic film, leaving a few small holes for ventilation.

Water and fertilizer: After the seedlings are planted, you can water them once a day, but the amount of water should be controlled to just moisten the soil. When the seedlings are about 40 to 60 centimeters tall, you can reduce the frequency of watering and water them every two or three days on average, but be sure to water them thoroughly and loosen the soil every time you water them. In terms of fertilization, urea solution can be applied every three or four weeks, and compound fertilizer solution can be added once during the fruit setting period.
