Culture: Harvesting watermelon at proper ripeness is an art. Thumping should produce a low, hollow sound. Spread thumb and forefinger and press hard on fruit. If you feel any give, watermelon is ripe. Don’t heed the traditional advice to wait for the closest tendril to brown—that may be too late. Minimum germination temperature 60°, optimal range 75–95°.
