In the sweet, juicy land of watermelons ¡®Crimson Sweet¡¯ reigns supreme. Large, round melons are beauties: light-green with dark-green stripes, and golden-yellow rinds. Heirloom¡¯s flesh is dark-red, firm, and fine-textured. Garden Hint: Grow on mulch to control weeds, conserve soil moisture, and protect fruit by keeping it off the ground.
