Common Questions
Frequently Asked Questions
Why does my begonia rex have Crispy leaves?
Cause: Begonia rex cultivars (including 'Frosty', 'Escargot') develop crispy leaf margins and edges due to foliar mineral salt accumulation from tap water irrigation and humidifiers. The delicate, textured leaves of rex begonias wick and retain minerals, causing localized tissue necrosis that appears as asymmetric browning and crisping along leaf edges. This condition is distinct from humidity deficits and represents a water quality issue rather than moisture stress.
Solution: Switch to Brita-filtered, distilled, or rainwater for all plant watering and humidifier filling immediately
Prevention: Use filtered, distilled, or rainwater exclusively for both irrigation and humidification; avoid misting which concentrates minerals on leaf surfaces; maintain 60-70% humidity via pebble trays rather than evaporative humidifiers; flush soil monthly with distilled water to prevent mineral buildup.
