Gourd Seeds,
Peru Sugar Bowl

Plant after the last frost, when soil temperatures reach 70 F. Growers with a shorter growing season should start seeds indoors three weeks before the last frost. If you’re unsure of your last frost date, consult our blog post 'Our Experts Answer Questions, Share Resources.’

Sow seeds 1 inch deep in rich, well-draining soil. Space plants 18-24 inches apart and provide a sturdy trellis to support the long vines. Mulch heavily to retain moisture and suppress weeds. Transplant seedlings outdoors only after the risk of frost has passed.

Water deeply, providing 1-2 inches per week, ensuring the soil stays moist but not waterlogged. Train vines along a trellis for vertical growth or allow them to sprawl across the ground. Fertilize with a nitrogen-rich fertilizer early in the season, then switch to a phosphorus-rich fertilizer when flowering begins. Hand-pollinate flowers if necessary to improve fruit set.

• Gourds are easily cross-pollinated, so it is advisable to isolate different seed-saving varieties up to 1/2 mile to ensure seed purity.
• A minimum of 15 plants of each variety should be grown to avoid inbreeding issues. Harvest fruit before it has dried out when it is still green in color but has developed a tough skin.
• Scoop seeds to dry; they will remain viable for about 4 years when stored properly in a sealed container in the refrigerator.
