How to Germinate Sweet Pea Royal Family

How to Germinate Sweet Pea Royal Family (Lathyrus odoratus)

  • Sow Sweet Pea seeds directly outdoors in early spring as soon as the soil can be worked, or in late fall for an early bloom the following season.
  • For faster germination, soak seeds in water for 12-24 hours before planting, or nick the seed coat with a nail file to help them sprout.
  • Plant seeds 1 inch deep in well-draining soil, spacing them 4-6 inches apart in rows or clusters.
  • Maintain a soil temperature of 55-65°F (13-18°C) for optimal germination, which typically takes 7-14 days.
  • Keep the soil consistently moist during the germination period, but avoid overwatering to prevent seed rot.

Additional Tips

  • Sweet Pea Royal Family thrives in full sun and prefers rich, well-draining soil. Incorporate compost or well-rotted manure into the soil before planting.
  • Provide a trellis or support structure, as these plants are climbers and will need something to grow on.
  • Water regularly to keep the soil moist, particularly during dry periods. Mulching around the plants helps retain moisture and keep roots cool.
  • Pinch off the growing tips when seedlings reach 4-6 inches in height to encourage bushier growth and more flowers.
  • Deadhead spent flowers frequently to encourage continuous blooming throughout the season.
