  • Water in the morning to allow the leaves and fruits to dry before night, which helps prevent fungal diseases.

  • Watermelons are ready to harvest when they sound hollow when tapped, the underside of the fruit turns a light yellow color, and the skin becomes rough.

  • Cut the watermelons carefully with a sharp knife. Leave a piece of the stem on the fruit to prolong its shelf life.

  • Harvesting usually occurs around 80-90 days after sowing, but this can vary depending on the variety and growing conditions.

Remember that watermelons are vigorous plants and need space to grow. Although they can be grown in pots, it is preferable to use larger containers to provide a suitable environment for the plant to grow.
