Growing Information

Planting

  • Plant seeds in full sun once soil has warmed to at least 70°F.
  • Space plants widely, allowing enough room for vines to reach their mature spread of 72–96 inches.
  • Sow seeds 1 inch deep in well-drained soil and provide warmth to support rapid early growth.
  • Thin seedlings to the strongest plant in each hill to encourage vigorous development.
  • Expect vigorous vines reaching 12–18 inches in height as fruit begins to size.
  • Water deeply after planting to establish roots and promote uniform germination.

Maintenance

  • Provide consistent moisture as vines expand, especially during fruit set and sizing.
  • Mulch around plants to conserve soil moisture and reduce weed pressure.
  • Give plants ample room as vines spread widely, reaching several feet in every direction.
  • Monitor leaves and stems for signs of stress, though this variety offers strong resistance to anthracnose and fusarium wilt.
  • Avoid overhead watering to keep foliage dry and encourage healthier vines.

Harvest & Storage

  • Harvest Crimson Sweet watermelons about 80–90 days after planting when the underside turns creamy yellow.
  • Check that the tendril nearest the fruit has dried, which is a strong indicator of ripeness.
  • Handle the 25-pound melons carefully to avoid bruising the rind during harvest.
  • Store whole melons in a cool, shaded area for up to a week before refrigeration.
  • Refrigerate cut pieces immediately to maintain sweetness and texture.
