terrarium growing on Bromeliad
Quick answer
If your Bromeliad has terrarium growing, the most likely cause is: Bromeliads growing in terrariums face unique challenges because the enclosed environment traps humidity and limits air circulation — creating ideal conditions for fungal diseases like Botrytis blight while simultaneously preventing the consistent air movement bromeliads need. Terrarium-grown bromeliads also risk overheating when placed under glass in direct sunlight.
Start here:
- 1. Use terrariums with mesh tops or ventilation holes of at least 2 inches in diameter
- 2. Keep terrarium bromeliads in bright indirect light, never in direct sun which overheats the enclosure

How to reverse terrarium growing on Bromeliad
- 1
Use terrariums with mesh tops or ventilation holes of at least 2 inches in diameter
- 2
Keep terrarium bromeliads in bright indirect light, never in direct sun which overheats the enclosure
- 3
Select atmospheric Tillandsia species for terrariums — they do not need standing water in a cup
- 4
If growing tank bromeliads in a terrarium, open the lid for 1-2 hours daily to allow air exchange
- 5
Monitor temperature inside closed terrariums — they can reach 100°F+ in direct sun, fatal to bromeliads
- 6
Avoid misting the inside of terrariums after 4 PM as this creates conditions for overnight fungal growth
