brown spots on Bromeliad
Quick answer
If your Bromeliad has brown spots, the most likely cause is: Brown spots on bromeliad leaves appear as either fungal infections (typically with concentric ring patterns or yellow halos) or as mineral burn from water droplets left on leaf surfaces in direct sunlight, which acts as a lens burning the leaf tissue. The distinction matters because fungal infections require fungicide treatment while simple sunburn requires moving the plant to shade.
Start here:
- 1. If spots appear after the plant was wet in direct sun: this is sunscald, move to bright indirect light immediately
- 2. If spots have concentric rings or yellow halos: this is likely a fungal infection, apply copper fungicide

How to reverse brown spots on Bromeliad
- 1
If spots appear after the plant was wet in direct sun: this is sunscald, move to bright indirect light immediately
- 2
If spots have concentric rings or yellow halos: this is likely a fungal infection, apply copper fungicide
- 3
Remove affected leaves by cutting at the base with sterilized scissors to prevent spread
- 4
When watering tank bromeliads, pour water into the cup without splashing the leaves
- 5
Water in the morning so any accidental leaf splash dries before direct sun reaches the plant
- 6
Improve air circulation to prevent fungal spores from establishing on wet leaf surfaces
Keep brown spots off this Bromeliad
Water tank bromeliads carefully without wetting leaves; avoid direct sunlight on wet leaves; maintain air circulation.
