Tips and Tricks

  • Choosing materials is crucial when it comes to orchid varieties. For example, Terrestrial orchids prefer sphagnum moss and epiphytes like mossy limbs.
  • While growing Terrestrial orchids, always go for a denser mix. Sand and sphagnum moss or coco peat works best.
  • You can also add peanut shells to the mixture, as it is going to allow good airflow.
  • For moth orchids, use 80% fir bark along with 20% sphagnum peat for best results.
