Reasons and Solutions for Yellowing Leaves of Potted Cyclamen

Cyclamen is a perennial herbaceous plant of the genus Cyclamen in the family Primulaceae. It likes light but fears strong light, so weak light exposure every day is enough. Exposure to direct sun will cause the leaves to turn yellow. When the flowers bloom paler and paler, it is related to insufficient light and insufficient fertilization. Fertilizer must be a specialized fertilizer, otherwise it will also cause the leaves to turn yellow. Now let us take a look at what to do when cyclamen leaves turn yellow!

Long-term fertilizer deficiency

If cyclamen has not been given nitrogen fertilizer for a long time or the pot and water have not been changed, and the water lacks nitrogen and other nutrient elements, the branches and leaves will become weak, and the leaves will be thin and yellow. It is necessary to promptly replace it with new culture water and gradually apply more dilute decomposed liquid fertilizer or compound flower fertilizer.

Excessive fertilization

If cyclamen is over-fertilized, the new leaves will be thick and fleshy with many uneven bumps, and the old leaves will have dry tips, turn scorched yellow, and fall off. In this case, fertilization should be stopped immediately, and the amount of water changed should be increased so that the fertilizer is washed away, or the pot should be turned out immediately, the tuber rinsed with water, and then replanted into the pot.

Pesticide spray too concentrated

Cyclamen suffering from pesticide damage will also show yellowing leaves. In this case, clean water should be sprayed promptly to alleviate it.

Hot high temperatures

If cyclamen is placed in a high-temperature location and exposed to direct strong light, it is very easy to cause the leaf tips and leaf margins of young leaves to become scorched, or the leaves to turn yellow and fall off. It only needs to be moved promptly to a well-ventilated, cool place.

Excessive shading

If cyclamen is kept in a shaded place or a place with insufficient light for a long time, it will also cause the branches and leaves to turn yellow. It only needs to be moved promptly to a new environment with good light.

Soil and water on the alkaline side

If the soil used for growing cyclamen lacks absorbable soluble iron and other elements, the leaves will gradually turn yellow. Therefore, acidic soil and water should be used when planting, and alum fertilizer water should be applied frequently during the growing period.

Too dense and poorly ventilated

If cyclamen is given too much nitrogen fertilizer, the branches and leaves will grow too luxuriantly, and combined with a long period without pruning, the inner branches and leaves will receive insufficient light, which can easily cause the leaves to turn yellow and fall off. Fertilization should be reasonable and pruning strengthened so as to provide ventilation and light penetration.

Dry air

When the indoor air is overly dry, cyclamen often shows phenomena such as dry leaf tips or scorched leaf margins. Attention should be paid to methods such as spraying water and covering with plastic film to increase air humidity.
