orchid bark mix on Bromeliad
Quick answer
If your Bromeliad has orchid bark mix, the most likely cause is: Bromeliads require an epiphytic growing medium because their roots evolved for attachment to tree bark, not for water absorption. Standard potting soil lacks the rapid drainage and air porosity that bromeliad roots need — when water fills the air pockets in regular soil, root cells cannot access oxygen and begin dying within 48 hours, allowing Pythium and Fusarium to colonize.
Start here:
- 1. Mix 70% fir bark (orchid bark) with 30% perlite for excellent drainage and aeration
- 2. Sphagnum moss alone works well for species with fine roots, but stays wet longer
