Watermelon Seeds,
Crimson Sweet

Start seeds indoors 3–4 weeks before your last frost date or direct sow outdoors when soil temperatures reach 70°F or higher. Wait until all danger of frost has passed before transplanting. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Sow seeds 1 inch deep, directly into raised hills or rows spaced 3–4 feet apart. Plant 2–3 seeds per hill, and thin to the strongest seedling once true leaves develop. Choose a sunny location with fertile soil and avoid planting near cucurbits grown in the previous season.

Water deeply 1–2 times per week and avoid overhead watering to reduce disease. Fertilize with a balanced, organic formula when vines start to run and again during flowering. Keep fruits off the ground using straw or melon cradles to prevent rot. Harvest when the bottom spot turns creamy yellow and the tendril nearest the stem is dry.

• Choose fully ripe or overripe fruits from healthy, true-to-type plants.
• Scoop seeds from the flesh and rinse in a strainer to remove pulp.
• Spread seeds on a screen or paper towel in a warm, dry place out of direct sunlight for 7-10 days.
• Stir daily to ensure even drying.
• Once completely dry, store in an labeled, airtight container in a cool, dark place.
