Watermelon Growing Best Practices

• You will need to purchase a pollinator for use with the seedless watermelon varieties. We highly recommend that you use Side Kick or Accomplice for this purpose, as they flower early and continuously throughout the pollination period.
• Choose the variety based on your climate
• Give watermelon seeds plenty of sunlight and room to grow
• Plant outside 2-3 weeks after your last frost date. Sow 3-4 seeds 1 inch deep, 4-5 feet apart.
• You want watermelon seeds to grow deep so water slowly and deeply. Avoid getting leaves wet to avoid powdery mildew 
• Mulch the plants well and feed them throughout the growing season
