When exposed to high temperatures, Cyclamens stop blooming. Their leaves are turning yellow. The plant goes into a dormant state. The pot with the tuber can be removed from the windowsill before growth begins in the autumn.
Exposure to high temperatures (above 18-20°C) stresses cyclamen, leading to a halt in flowering, slower development, and even the death of flower buds. To stimulate flowering, cyclamen requires cool temperatures (16-18°C during the day and 2-3 degrees cooler at night), bright, filtered light, and moderate humidity.
