No, you should not use cactus soil for orchids.
Cactus soil is designed to be well-draining and gritty, which is ideal for cacti and succulents that require low moisture levels. Orchid, on the other hand, prefer a more humid environment and require a potting mix that retains moisture better.
Using cactus soil for orchids could lead to:
- Root rot: The poor drainage of cactus soil can cause the orchid’s roots to sit in water, leading to rot.
- Nutrient deficiencies: Orchid require specific nutrients that may not be present in cactus soil.
- Stunted growth: The lack of moisture retention in cactus soil can hinder the orchid’s growth.
For orchids, it’s best to use a potting mix specifically formulated for epiphytes. These mixes are typically composed of bark, moss, and perlite, which provide good drainage while also retaining moisture.
