Why does your Dahlia Waikiki Beach have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyDahlias with large, lush foliage like the Waikiki Beach variety have high transpiration rates. When soil moisture is insufficient, the plant loses turgor pressure, causing the leaves to wilt and droop to conserve water.
Excessive moisture in heavy soils leads to Phytophthora or Pythium species, which destroy the tuber's ability to transport water. This paradoxically causes leaves to droop as if the plant were thirsty because the roots are no longer functional.
High humidity or wet foliage can trigger Botrytis, which attacks the stems and leaf tissue. As the fungus degrades the structural integrity of the stem, the leaves will begin to sag and eventually develop brown spots.
Extreme afternoon heat can cause 'transpiration imbalance' in large-leafed Dahlias. If the plant cannot move water to its leaves fast enough to cool down, the leaves will wilt temporarily during peak sun hours.
