Description

(Citrullus lanatus). This watermelon produces 20-lb fruit with a light pea-green, sunburn-resistant rind. It is also one of the most drought-resistant varieties of watermelon known. It has sweet, yellow flesh and is very popular in the watermelon-growing areas of Arkansas. Good for storage.

Growing Tips: Desert King thrives in heat and can tolerate drought conditions better than most watermelons. Choose a full-sun location with sandy, well-drained soil. Deep, infrequent watering promotes strong root systems. Use mulch to suppress weeds and retain moisture. This variety also stores well after harvest, offering a longer shelf life than most melons.

When to Grow

Start seeds indoors 3–4 weeks before your last frost or direct sow outdoors once soil temperatures reach 70°F. Transplant seedlings only after the danger of frost has fully 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 1 inch deep per hill or spaced in rows. Space mounds 3–4 feet apart and rows 5–6 feet apart. Thin to the strongest seedling once true leaves emerge. For best results, amend soil with compost or aged manure before planting.

How to Grow

Water deeply once a week, especially during flowering and fruit set. As fruit nears maturity, reduce watering to enhance sweetness and prevent cracking. Fertilize at planting and again when vines begin to run. Keep fruit off soil to prevent rot and monitor for pests such as 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.
