|'Crimson Sweet' is generally ready for harvest 100 days after sowing. These melons weigh up to 25 pounds. They have light green rinds with darker green longitudinal striping. Flesh is salmon-colored, and sweet. Watermelons generally do best in warm climates. Cool weather will not produce good fruits, but some of the adversity of cool weather can be overcome by starting seeds early indoors, and transplanting them out at the height of summer. Plastic groundcovers are highly recommended to increase soil temperature in the spring, and rowcovers will help the crop ripen in the fall.
