Why does your Canna Cannova Bronze Scarlet have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Canna lilies are heavy drinkers with large leaf surface areas that promote rapid transpiration. When soil moisture is depleted, the plant loses turgor pressure, causing the large bronze leaves to wilt rapidly.
While Cannas love moisture, waterlogged soil deprives roots of oxygen, leading to fungal pathogens like Phytophthora. This damages the vascular system, making it impossible for the plant to transport water to the leaves despite wet soil.
The 'Bronze Scarlet' cultivar has large, dark pigments that can absorb intense solar radiation. During extreme heatwaves, the plant may wilt during midday to conserve moisture, even if soil levels are adequate.
Canna lilies are heavy feeders; a lack of nitrogen can weaken the structural integrity of the leaf stalks. While usually accompanied by yellowing, severe deficiency can lead to weakened stems that cannot support the large foliage.
