Watermelons love warmth! Planting seeds or seedlings too soon, before soil temperatures reach 70°F (21°C), can stunt growth or cause seeds to rot. Always wait for consistent warmth.
Watermelons are heavy feeders and need nutrient-rich, well-draining soil. Skipping soil tests or failing to amend with compost and organic matter leads to weak vines and bland fruit.
Watermelon vines spread wide and need room to thrive. Planting too close restricts airflow and sunlight, increasing the risk of disease and limiting fruit size.
Watermelons need deep, consistent watering—especially during fruit formation. Fluctuating moisture levels cause cracked rinds and bland taste. Aim for steady, deep soaks.
Without proper pollination, fruit will not develop. Lack of bees or hand-pollination efforts can lead to small, misshapen, or no melons at all. Encourage pollinators or manually assist.
Picking watermelons at the wrong time ruins all your effort. Watch for signs: yellowing underside, dried tendril near the stem, and a deep hollow sound when tapped.
