Key takeaways

• Watermelons grow best in loamy, sandy, well-drained soil with a pH that is ever so slightly acidic to neutral, in the range of 6.0 to 7.5.
• They thrive in warm temperatures ranging from 20 to 30 degrees Celsius, with annual rainfall of 600–1,200 millimeters, and need irrigation to maintain consistent moisture levels.
• Selecting elite hybrid seeds, such as Sweet Rose F1, Crimson Sweet, and Sugar Baby, enhances crop yield and quality.
• The optimal time for planting is February or March for maximum growth and market returns, with a maturation period of 3–4 months.
• Fertilizers such as cow dung, Di Ammonium Phosphate (DAP), and Poly Sulphate to promote development guarantee growth, while correct watering and soil drainage prevent degradation and stunted growth.

Q: How often should I water

Watermelon grows well in areas with warm weather. To cultivate it, choose a sunny spot with well-drained soil. Here is a guide on how to cultivate watermelons for beginners:

• Gap between rows should be approximately 0.9 to 1.8 meters apart, and each plant should be spaced about 0.9 to 1.2 meters apart.
• Dig holes that are approximately two times as deep and wide as the root ball.
• Use well-rotted manure or compost in every planting hole.
• Place a seedling in each hole and cover its roots with soil gently.
• Provide the seedlings with a generous amount of water to aid their initial growth.
• Maintain consistent soil moisture by avoiding overwatering; watermelons require around 2.5 cm of water each week from either rainfall or irrigation.
• Support the plants with a trellis or stakes to prevent the fruit from coming into contact with the ground.

What is the ideal month for planting watermelon?

In March, the weather is generally favorable, providing ideal growing conditions for melons and supporting market demand when properly irrigated. Nevertheless, since water can be a limiting factor, planting melons in February allows for more favorable Return on Investment, as the available stock in April and May will be limited, minimizing excessive market supply.

How long does it take for watermelon to mature?

To determine when a watermelon is ready to be harvested, depends on the type and environmental conditions. Identifying when a watermelon is mature can be challenging. Check the underside of the melon for a light-colored or yellow spot; a white or pale green spot indicates that it needs more time to ripen.

Also, inspect the curved stem attached to the melon on the vine - when it becomes dry and turns brown, the melon is ready to be picked. Watermelons typically remain fresh for just over a week when stored at room temperature or about two weeks when refrigerated.
