Why does your Dahlia Bermuda Beach have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Dahlias have large, fleshy stems and leaves that require consistent moisture to maintain turgor pressure; drought causes the cells to lose water, resulting in immediate wilting.
Excessive moisture in the soil prevents oxygen from reaching the tubers, leading to fungal pathogens like Phytophthora that destroy the root system's ability to transport water.
High humidity and wet foliage can trigger Botrytis, which weakens the plant's vascular system and causes leaves to droop and eventually develop brown spots.
Extreme midday temperatures can cause 'temporary wilting' where the plant transpires water faster than the roots can replace it, even if soil moisture is adequate.
