bromeliad

Cause: Bromeliads are monocarpic; the mother rosette naturally dies after its single bloom cycle to redirect energy toward producing basal offsets (pups). This is often mistaken for disease or drought as leaves brown and curl from the center outward.

Solution: Cut the faded flower stalk at its base with sterile shears.

Prevention: Natural lifecycle; support pup vigor with high humidity (60%+) and bright indirect light.

Cause: Sap-sucking armored scale insects appearing as raised, waxy brown spots that can be physically scraped off. They thrive in low-airflow environments.

Solution: Isolate the plant immediately.

Prevention: Quarantine new plants for 2-4 weeks. Improve air circulation and inspect leaf axils monthly.

Cause: Fungal infection (Rust) characterized by brown necrotic spots surrounded by distinct yellow (chlorotic) halos. Triggered by high humidity and stagnant air.

Solution: Prune and discard infected leaves using sterilized tools.

Prevention: Maintain humidity between 50-70% with active ventilation. Water the central cup or soil directly.

Cause: Epiphytic bromeliads rely on their central 'tank' (urn) for hydration. Curling or browning leaves often result from watering the soil exclusively or allowing the tank water to become stagnant.

Solution: Keep the central cup 1/4 to 1/3 full of distilled, rain, or filtered water.

Prevention: Use low-mineral water to avoid tip burn. Maintain a regular tank-flushing schedule.

Cause: Direct midday sun causes bleached or crispy brown necrotic patches on thin-leaved species like Vriesea and Guzmania. Their foliar trichomes are adapted for filtered forest light.

Solution: Relocate the plant to bright indirect light (East or West window with sheer curtains).

Prevention: Acclimate gradually to higher light. Use 30-50% shade cloth if moving outdoors.
