How to Germinate Albizia julibrissin Northern

How to Germinate Albizia julibrissin Northern

  • Soak Albizia julibrissin Northern seeds in warm water for 24 hours to soften the hard seed coat and improve germination.

  • Plant seeds 1/2 inch deep in well-draining soil in a sunny location.
  • Keep the soil consistently moist but not waterlogged during the germination period, which typically takes 14-21 days.
  • If starting indoors, transplant seedlings outdoors once they have grown 3-4 inches tall and all risk of frost has passed.
  • Space seedlings at least 10-15 feet apart to accommodate the tree's mature size.
