Propagating Begonia Maculata


Begonia Maculata can be easily propagated from stem cuttings or by division.

From Stem Cuttings:

  • For stem cuttings, select a healthyBegonia Maculata stem that has at least one node and several leaves. Cut the stem just below a node, removing any lower leaves.
  • Dip the cut end of the stem into rooting hormone and plant it into a well-draining potting mix. Keep the soil moist and the cutting in a bright, warm spot out of direct sunlight.
  • Cover the cutting with a plastic bag to create a mini greenhouse and promote humidity.
  • After a few weeks, you should see roots beginning to form.
  • Once the cutting has established roots and new growth, it can be transplanted into its own pot.

From Division:

  • Gently remove the Begonia Maculata from its pot and gently separate the root system into smaller sections. Each section should have at least one stem and several leaves.
  • Plant each section into its own pot with fresh, well-draining potting mix. Water the newly potted sections and place them in a bright spot with indirect sunlight.
  • Keep the soil moist but not waterlogged, and mist the leaves regularly to promote humidity.
  • With proper care, propagated Begonia Maculata plants can grow and thrive just as well as the original plant.

Note: Both stem cuttings and division should be done during the plant’s active growing season, typically in the spring or summer months.
