Why does your Cyclamen persicum have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Cyclamen are highly susceptible to fungal pathogens like Phytophthora when soil remains saturated. Excessive moisture leads to the decay of the tuber, causing the plant to shed leaves rapidly as it loses the ability to transport water.
Persian Cyclamen are cool-season plants that thrive in temperatures between 13°C and 18°C. Exposure to heat above 24°C causes physiological stress, leading the plant to enter a dormant-like state characterized by leaf drop.
High humidity and poor air circulation can trigger Botrytis cinerea, which attacks the leaf tissue. As the fungal infection spreads, the leaves wilt and drop from the tuber.
After a blooming period, Cyclamen naturally enter a period of dormancy where they cease active growth and shed foliage. This is a biological process often triggered by changes in light or temperature.
