What to Do When Cyclamen Leaves Turn Yellow? Detailed Solutions

I bought a pot of cyclamen at the flower market over a week ago, repotted it myself and watered it thoroughly, and the room temperature has stayed around 23°C. A week later I watered it again, and now I've noticed the leaves are gradually turning yellow. Could it be that I overwatered it?

Answer: Cyclamen is a semi-hardy bulbous flower that likes cool, humid and sunny conditions. Autumn, winter and spring are its growing seasons. Its most suitable growing temperature is 15-20°C. Under such conditions, cyclamen needs attention to humidity: on one hand, water when the potting soil or substrate is dry; at the same time, pay attention to frequently spraying water on the leaves and around the pot to make the air relatively humid. Yellowing and wilting leaves are very likely caused by insufficient humidity. If the cyclamen you bought was grown in substrate, the possibility of water loss is greater, so pay attention to maintaining humidity.

Cyclamen originates from the Mediterranean coast, in Greece, Syria and other places. Cyclamen likes a warm, humid and cool climate; in warmer areas it can be cultivated in outdoor cold frames, and it is suited to well-drained, humus-rich, fertile acidic soil. Its flowering period is long, lasting from September all the way to April-May of the following year. The suitable growing temperature is 15-18°C; if the temperature is too high, it easily grows leggy and rots. June to September is the dormant period. During dormancy the temperature should not exceed 30°C. For plants entering dormancy, the dry leaves should be removed and the plant placed in a cool, ventilated spot; when dry, water a little clear water, and be careful to keep the potting soil moist but not too wet, otherwise the corm will rot and the plant will die. If it can be placed in a cool, ventilated and humid spot before dormancy arrives, with daily spraying to lower the temperature and retain moisture so the leaves do not drop, it can both increase the plant's crown spread and bloom earlier.

 Cyclamen is a beautiful ornamental flower. Many people like to grow it as a potted plant and place it indoors, as it can both beautify the indoor environment and purify indoor air.

Because no nitrogen fertilizer has been applied for a long time or the pot has not been changed, cyclamen lacks essential nutrients during growth and develops yellow leaves. At this point, culture solution or a well-diluted nitrogen fertilizer should be applied in time.

2. Overfertilization

Overfertilization can also make cyclamen leaves turn yellow. Although cyclamen likes fertilizer, it must be applied in measured amounts. If too much fertilizer is applied, the potting soil can be changed promptly to dilute the fertilizer, and the symptoms of yellowing leaves will improve.

3. Overwatering

Overwatering is also an important cause of cyclamen leaves turning yellow. Lack of water is bad for cyclamen's growth, and overwatering is also bad for it. If watered excessively at one time, water will accumulate in the cyclamen's pot, and when the accumulation is serious it will cause root rot in the cyclamen, and the leaves will turn yellow too; if not dealt with in time, the cyclamen may even die. Besides this, light conditions are also an important cause of cyclamen leaves turning yellow. If it does not see sunlight for a long time, the leaves will turn yellow. The best solution is to move it every afternoon to an environment with ample sunlight, and after a period of time the symptoms of yellowing leaves will disappear.

Some friends find that the cyclamen they grow blooms with increasingly pale colors, and the leaf edges turn yellow. Why is this?

To prevent cyclamen from lacking water, some people not only water excessively at one time when watering, but also keep water in the saucer under the pot, which is bad for cyclamen's growth. Standing water in the saucer will instead cause root rot in cyclamen. At a temperature of 17°C-18°C, watering cyclamen once every 3 days is enough; wait until the soil is completely dry before watering.

Cyclamen likes light but fears strong light, so it cannot be exposed to full sun; a little sunlight each day is enough. The main reason cyclamen flowers bloom paler and paler is related to insufficient light and insufficient fertilization. It should be especially noted that most cyclamen sold at flower markets today are given professional fertilizer and watered with softened water before being marketed, so the flowers grown this way are especially vivid. That is why they are so hard to grow well. It is suggested that flower lovers who grow cyclamen water them with purified water or boiled water that has been left to cool for a day after buying them, and apply professional fertilizer once every half month.
