How to Germinate Cardinal Climber

How to Germinate Cardinal Climber (Ipomoea quamoclit x sloteri)
  • Sow Cardinal Climber seeds indoors 4-6 weeks before the last expected frost date, or directly outdoors after the danger of frost has passed.
  • Soak seeds in warm water for 24 hours before planting to soften the hard seed coat and improve germination rates.
  • Plant seeds 1/4 inch deep in seed-starting trays or directly in the garden soil.
  • Keep the soil consistently moist and maintain a temperature of 70-75°F (21-24°C) for optimal germination, which usually occurs within 7-14 days.
  • If starting indoors, transplant seedlings outdoors once they have developed several sets of true leaves and the soil has warmed up.
  • Space the seedlings 6-12 inches apart and provide a trellis or support structure for climbing.

Additional Tips
  • Cardinal Climber thrives in full sun and well-draining soil, though it can tolerate partial shade.
  • Water regularly, especially during dry spells, but avoid waterlogging as the plant prefers slightly dry conditions.
  • Apply a balanced, slow-release fertilizer to support healthy growth and abundant flowering.
  • Provide a trellis or other support for the vines to climb, as Cardinal Climber grows vigorously.
  • Deadhead spent flowers to promote continued blooming throughout the growing season.
