How to Germinate California Bluebell

How to Germinate California Bluebell (Phacelia campanularia)

  • Sow California Bluebell seeds directly outdoors in early spring or fall, as they prefer cooler temperatures for germination.
  • Prepare a well-draining seedbed by loosening the soil and removing any weeds.
  • Scatter seeds on the soil surface and press them gently; do not cover, as they need light to germinate.
  • Water gently to keep the soil consistently moist but avoid waterlogging, which can harm the seeds.
  • Germination typically occurs within 7-14 days, depending on environmental conditions.
  • Thin seedlings to 6-8 inches apart to allow for proper air circulation and growth.

Additional Tips

  • California Bluebell prefers full sun and well-draining soil, but it can tolerate partial shade, especially in hotter climates.
  • Water regularly, especially during dry spells, to keep the soil moist and encourage blooming.
  • Apply a thin layer of mulch to retain soil moisture and reduce weed growth around the plants.
  • Deadhead spent flowers to encourage continuous blooming and prevent unwanted self-seeding.
  • These annuals can reseed themselves, so leave some flowers to mature and drop seeds if you want them to return the following season.
