Planting Too Early: Watermelons need warm soil to grow. Planting too early can stunt growth and reduce yields. Wait until the soil temperature is consistently above 70°F.
Poor Soil Drainage: Watermelons need well-draining soil. Avoid planting in areas with heavy clay or poor drainage, as this can lead to root rot.
Overcrowding Plants: Watermelons require space to spread out. Crowding plants together can lead to poor air circulation, increasing the risk of disease.
Inconsistent Watering: Watermelons need consistent watering, especially during fruit development. Irregular watering can cause the fruit to crack or become misshapen.
Not Using Mulch: Mulch helps retain moisture, suppress weeds, and regulate soil temperature. Without it, watermelons may suffer during hot, dry weather.
Ignoring Pollination: Watermelons rely on bees for pollination. Lack of pollinators can reduce fruit production, so encourage bees by planting nearby flowers.
Over-fertilizing: Too much nitrogen can result in lush vines with few fruits. Use a balanced fertilizer to promote healthy growth.
Harvesting Too Soon: Watermelons should be fully ripened before picking. Look for the "thump" sound and a yellow underside to know when they’re ready.
