Why does your Chrysanthemum lavandulifolium have drooping leaves? Diagnose the cause and fix it with our step-by-step guide.
Chrysanthemums have relatively shallow root systems that are sensitive to dry spells. When the soil moisture drops too low, the turgor pressure in the leaves decreases, causing the characteristic limp or drooping appearance.
Excessive moisture in the substrate leads to anaerobic conditions, causing Pythium or Phytophthora species to attack the roots. As roots decay, they can no longer transport water to the foliage, resulting in leaves that appear wilted despite wet soil.
This fungal pathogen invades the vascular system of the Chrysanthemum, physically blocking the xylem. This prevents water from reaching the upper leaves, leading to progressive drooping and eventual browning.
Extreme-high temperatures increase the transpiration rate beyond the plant's ability to pull water from the roots. This temporary loss of turgidity is common in Chinese Chrysanthemums during midday heat waves.
