Tips

• Sow seeds 1 inch deep when soil is at least 65°F and thin to 3-4 feet apart.
• Water deeply beneath the canopy, providing about 1-2 inches weekly during fruit development.
• Allow vines to spread or provide a strong trellis and support hanging fruit in slings.
• Look for squash bug egg clusters beneath leaves and powdery white mildew patches on foliage.
• Harvest when fruit reaches its variety-specific mature color and has a hard rind, leaving a short stem and curing sound fruit in warm, airy conditions.
