Description

(Citrullus lanatus). An American classic that produces long, oval-shaped fruit with very sweet and crisp flesh of deep red. A popular old favorite. Large size. One of the all-time best tasting melons! This southern classic was developed in Leesburg, Florida, in the early 1960s.

Growing Tips: Jubilee watermelon performs best in full sun with rich, sandy, well-drained soil. Mulch to retain soil moisture and suppress weeds, and use drip irrigation to minimize disease risk. Provide ample space for its vigorous vines, and rotate crops yearly to prevent soilborne pathogens. Prune early vines to focus energy on fruit production.

When to Grow

Start seeds indoors 3–4 weeks before the last frost or direct sow once soil temperatures remain above 70°F. Transplant only after all danger of frost has passed and soil is consistently warm. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow 2–3 seeds per hill, spaced 3–4 feet apart, planting each seed 1 inch deep. Thin to the strongest seedling once true leaves develop. For row planting, space plants 3 feet apart in rows 5–6 feet apart. Choose a sunny, well-aerated site with fertile soil enriched with compost or aged manure.

How to Grow

Water deeply 1–2 times per week, adjusting based on rainfall and stage of growth. Reduce watering as fruit nears ripeness to improve sweetness. Fertilize at planting and again when vines begin to run. Provide support for fruit if using vertical growing systems. Monitor for pests like cucumber beetles and squash bugs.

How to Save Seeds

  • 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.
