    Contains about 90–92% water. Helps prevent dehydration, especially during hot weather.

Possible Harms of Watermelon

  1. Overconsumption
    Eating too much can cause bloating, diarrhea, or stomach upset.

  2. Concerns for Diabetics
    Due to high natural sugar, diabetic individuals should consume it in moderation.

  3. During Pregnancy
    Pregnant women should be cautious of nitrates in early-harvested or chemically treated watermelons.

  4. Nitrate Content
    Improperly grown watermelons may contain harmful levels of nitrates.

Cultivation Methods of Watermelon

1. Climate and Soil

Requires a warm climate, full sun, and fertile, well-drained soil.

2. Seed Selection

Choose high-quality, disease-resistant seeds adapted to the local environment.

3. Planting

Plant after the last frost. Sow seeds 2–3 cm deep and 1.5–2 m apart.
