Bromeliads, a diverse group of epiphytic plants, have captivated plant enthusiasts with their vibrant foliage, exotic flowers, and unique adaptations to their arboreal lifestyle. Growing in the canopy of rainforests, these plants exhibit remarkable resilience and a range of ecological benefits, making them valuable additions to any collection or ecosystem.
Bromeliaceae, the bromeliad family, comprises over 3,600 species distributed across 58 genera. They are primarily found in tropical and subtropical regions of the Americas, with a few species extending into Africa and Asia.
Key Characteristics:
Light: Most bromeliads prefer bright, indirect light.
Water: Water sparingly, allowing the central tank to dry out between waterings. Avoid overwatering.
Humidity: Bromeliads thrive in humid environments. Regular misting or placement on a humidity tray is beneficial.
Fertilization: Feed monthly with a balanced fertilizer during the growing season.
Common Pests: Mealybugs, aphids, scale, and spider mites.
Control: Use insecticidal soap or horticultural oil.
Common Diseases: Bacterial rot, leaf spot, and root rot.
Control: Improve drainage, remove infected leaves, and use proper sanitation practices.

|---|---|
| Pest/Disease | Symptoms | Control |
| Pests: | | |
| Mealybugs | White, cottony masses on leaves and stems | Insecticidal soap or horticultural oil |
| Aphids | Small, green or black insects on leaves and stems | Insecticidal soap or neem oil |
| Scale | Brown or white scales on leaves and stems | Horticultural oil or rubbing alcohol |
| Spider mites | Fine webbing on leaves; yellowing or browning of leaves | Insecticidal soap or neem oil |
| Diseases: | | |
