Croton Petra

Croton Petra (Codiaeum variegatum 'Petra') is beloved for its dramatic, multicolored foliage, but it is notoriously sensitive to sudden environmental changes. Leaf shedding is a physical stress response rather than an infectious disease, usually occurring when the plant adjusts to new growing conditions. Beginners typically notice healthy-looking, colorful lower leaves dropping off rapidly, or vibrant red and yellow hues dulling into plain green. This shock reaction often follows bringing the plant home from a nursery, repotting, or moving it to a new room. In Indian homes, direct exposure to cold air conditioner drafts during summer or sudden drops in ambient humidity after the monsoon season frequently trigger this issue. Keeping the plant in a bright, stable location with moderate humidity helps it acclimate and regrow lost foliage.
