Why does your Rieger Begonia have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Rieger Begonias have succulent-like stems and leaves that rely on high turgor pressure. When the growing medium dries out too much, the plant loses its ability to support its heavy foliage, leading to immediate wilting.
Excessive moisture in the substrate prevents oxygen from reaching the roots, causing them to decay. As the root system fails, it can no longer transport water to the leaves, paradoxically causing the plant to look wilted even in wet soil.
Rieger Begonias are tropical plants that are highly sensitive to cold drafts or sudden temperature drops. Cold air can cause the cells in the fleshy leaves to collapse, resulting in a limp, drooping appearance.
High humidity combined with poor air circulation can trigger Botrytis, which attacks the stems and leaf bases. The fungal infection weakens the structural integrity of the plant, causing the leaves to droop before dying.
