Base on the climate requirement, the reasonable temperature index of the environment for sweet watermelon is 70-80˚F for daytime and 65-70˚F for nighttime.


Despite the system of the deep root, the watermelon shows a low waterlogging tolerance. Only when the flower and fruit are available does the capacity against drought optimize.

The last section of the preparation is to use a tractor and scrape the soil, crush the large blocks; then remove grasses or place them into the ground.

  • Create a flat, slightly concave surface at the top of the mound

  • Use a finger or tool to make three to four holes in the soil, each about 2.5 cm deep.

  • Sow from one to four seeds into each hole, then rake and cover the ground so that seeds are well covered and free from moisture around the seed.

Noting sprouts

Seeds will usually germinate and pick up seedlings within 7-10 days, depending on soil temperature and seedling depth. Keep the soil around moist seed during germination; watering the water so that the water can penetrate the small roots forming.

When the seedlings have grown, only hold the two strongest trees, so that the healthy plants have space to grow. Do not let the soil dry; You should water at least once a day.
