Description

(Citrullus lanatus). This melon has a green rind and succulent red flesh with excellent flavor and sweetness. It is a beautiful melon and a favorite on our farm, easy to grow and producing fruit up to 20 lbs. One of the most fascinating seed discoveries in modern history! In the early 1920s, Art Combe, a Southwestern plant expert and amateur prospector, found a small woven pot filled with bright red watermelon seeds in an abandoned sandstone cave in Arizona’s Mogollon Rim. Art planted the seeds and just a few germinated. The fruit was small and crooknecked, unlike any other watermelon he had ever seen before, and the flavor was incredible! Art grew this watermelon for several decades, selecting the largest and most round specimens. The result of decades of selecting is a superb extra-large watermelon with bright red, very sweet flesh. (Some fruit may still have necks.) Art used a dry farming technique that allowed him to grow extra-sweet watermelons with almost no irrigation in the searing hot desert; these watermelons are extremely heat and drought tolerant!

Growing Tips: This variety is well adapted to heat and drought, making it a perfect choice for desert or arid-zone gardens. Choose a site with full sun and fast-draining soil. Deep, infrequent watering mimics the plant’s native environment and promotes strong root systems. Avoid overwatering, especially once fruit sets, to enhance sweetness and reduce cracking.

When to Grow

Start seeds indoors 3–4 weeks before the last spring frost or direct sow after the soil temperature reaches at least 70°F. Ensure all threat 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.'

How to Sow and Plant

Plant seeds in raised mounds or rows for improved drainage. Sow 2–3 seeds per mound at a depth of 1 inch, thinning to the strongest plant after emergence. Space mounds 3–4 feet apart in all directions. Use row covers early on to protect seedlings from pests until they are established.

How to Grow

Maintain even moisture early in the season, then reduce watering as fruits mature. Feed with compost or a balanced organic fertilizer at planting and again when vines begin to run. Prune vines to manage size and focus growth on fewer fruits. Monitor for cucumber beetles and fungal diseases in humid areas.

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.
