Watering. Water regularly to keep soil moist but not soggy, especially during flowering and fruit development. Reduce watering as fruits mature to improve sweetness.
Fertilizing. Apply a balanced fertilizer when planting and side-dress with nitrogen-rich fertilizer during vine growth. Avoid excess nitrogen once fruits start to develop to encourage sweetness.
Watermelon plants need warm temperatures and plenty of sunlight to grow well. They require regular watering but dislike waterlogged soil. Watch for pests like aphids and powdery mildew, and provide space for the vines to spread. Overall, they need moderate care and attention.
