Description

(Citrullus lanatus). Beautiful, deep orange flesh; very sweet, excellent, almost tropical flavor! The best-tasting of ALL orange varieties we tried—the favorite of many who tried it at our place. High yields. Very resistant to wilt and insects; strong healthy vines. These will sell at roadside stands & markets! Introduced by Willhite Seed Co. prior to 1965.

Growing Tips: Orangeglo watermelon thrives in full sun and well-drained, nutrient-rich soil. Use compost or aged manure at planting to promote vigorous vine growth. Mulch around the base of plants to conserve moisture, suppress weeds, and prevent soil splash. Water deeply and consistently for strong fruit development, especially during flowering and early fruiting.

When to Grow

Start seeds indoors 3–4 weeks before your last frost or direct sow outdoors once the soil reaches at least 70°F. Transplant or sow only after all risk of frost has passed. 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

Plant 2–3 seeds per mound, 1 inch deep. Space mounds 3–4 feet apart in rows 6 feet apart. Once germinated, thin to the strongest seedling. Choose a sunny, open site with good air circulation and amend soil with compost or a balanced organic fertilizer prior to planting.

How to Grow

Water thoroughly once or twice weekly depending on rainfall, reducing frequency slightly as fruits near maturity to improve sweetness. Fertilize again when vines begin to run and at first fruit set. Support fruits with straw or melon cradles and keep an eye out for cucumber beetles and fungal diseases in humid conditions.

How to Save Seeds

  • Allow fruit to ripen fully and cure on the vine before harvesting.
  • 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.
