2. For Division:

   • Carefully separate the root ball into sections, ensuring each section has roots and canes.
   • Repot the divisions in fresh orchid mix to give them a strong start.

Propagation can be a fun and fulfilling process, allowing you to share your love for orchids with friends or expand your own garden. With the right techniques, you'll be well on your way to growing a thriving collection.
