It is advised to water watermelon plants deeply, providing approximately 2 inches (5 cm) of water every week when no watermelons are visible on the vines. Once the vines start growing their first melons, the watering should be reduced to 1 inch (2.5 cm) per week. This adjustment ensures the plants receive the proper amount of water according to their growth stage. Furthermore, it is crucial to direct the water at the base of each watermelon vine, avoiding wetting the leaves and fruits. Watermelons prefer evenly moist soil, so it is important to avoid extremes of either too wet or too dry.

Watering Frequency For Watermelon Plants

The watering frequency for watermelon plants depends on various factors, such as temperature, soil composition, and local weather conditions. As a general guideline, watermelon plants typically need to be watered 1-2 times a week when temperatures remain below 90°F (32°C). This frequency is sufficient to maintain the moisture content of the soil and provide the plants with adequate hydration.

However, when temperatures climb above 90°F (32°C), watermelon plants may require daily watering to prevent the soil from drying out. In such conditions, it is important to monitor the soil moisture level closely and adjust watering accordingly. The goal is to keep the soil consistently moist to a depth of at least 12 inches (30 cm) at all times. This ensures the roots have access to an adequate water supply for optimal watermelon growth.
