The reasons for the yellowing of cyclamen leaves
Answering netizens' questions about the introduction of cyclamen, a bulbous flower, the reasons for the yellowing of cyclamen leaves, and the following is a comprehensive introduction.
Some people overwater cyclamen, and the roots will rot; some cyclamen flowers fade in color as they bloom, and the edges of the leaves turn yellow. Why is that? In fact, cyclamen does not like too much water, as excess water can cause root rot. However, cyclamen also cannot be water deficient, otherwise the leaves will wilt and droop, and they will recover as soon as water is added.
Some people are afraid that cyclamen will lack water, so they not only water excessively in one go but also let the water accumulate in the saucer under the pot, which is detrimental to the growth of cyclamen. Accumulated water in the saucer can lead to root rot. It is sufficient to water cyclamen once every 3 days at a temperature of 17-18°C, and water should only be added when the soil is completely dry. Additionally, avoid spraying water on the leaves and flowers of cyclamen.
Cyclamen enjoys light but is sensitive to strong light; it is sufficient to have weak light every day, and it should not be exposed to direct sunlight at noon. The fading of cyclamen flowers is related to insufficient light and insufficient fertilization. It should be noted that most cyclamen sold in the market today have been treated with professional fertilizers and watered with softened water, making the flowers particularly vibrant. However, it is difficult for consumers to care for them well after purchasing. It is recommended that cyclamen lovers water their plants with purified water or cooled boiled water after buying them and fertilize once every half month.
Cyclamen has a dormant habit in the summer. In June, after the flowers fall, the leaves turn yellow and fall off. At this time, the corm can be removed from the pot and placed in a plastic bag, then stored in the refrigerator. Make sure the refrigerator temperature does not drop below 0°C. After the beginning of autumn, remove the corm, prune the old roots and leaves, and replant it in the pot. When new leaves begin to sprout, gradually resume normal watering and fertilization.
(1) Long-term lack of fertilizer. Long-term absence of nitrogenous fertilizer or not changing pots and water can lead to a lack of nutrients like nitrogen in the water, causing the branches and leaves to become weak and the leaves to become thin and yellow. It is necessary to change to new culture water and gradually increase the application of thin, decomposed liquid fertilizer or compound flower fertilizer.
(2) Over-fertilization. Excessive fertilization can cause new leaves to become thick and uneven, with old leaves drying up, becoming尖 and falling off. Fertilization should be stopped immediately, water changed more frequently to let the fertilizer wash away, or the pot should be turned over, the corm washed with water, and then replanted in the pot.
(3) High temperature. If cyclamen is placed in a high-temperature area and exposed to strong sunlight, it can easily cause the young leaves to have burnt leaf tips and edges or yellowing and falling off. It should be moved to a well-ventilated, shady place in time.
(4) Excessive shading. If cyclamen is kept in a shaded area or place with insufficient light for a long time, it can cause the leaves to turn yellow.
(5) Soil and water too alkaline. Due to the lack of soluble iron and other elements that can be absorbed by the plant in the water, the leaves will gradually turn yellow. When planting, choose acidic soil and frequently water with alum fertilizer water during growth.
(6) Poor ventilation. If too much nitrogen fertilizer is applied, the branches and leaves will grow too lush, and if they are not pruned for a long time, the leaves inside the plant will not receive enough light, easily causing yellowing and falling off. Reasonable fertilization and pruning should be done to ensure ventilation and light.
(7) Dry air. When the indoor air is too dry, cyclamen often shows symptoms like dry leaf tips or burnt leaf edges. Measures such as spraying water or using a plastic film cover should be taken to increase humidity.
What to do when cyclamen leaves turn yellow
1. Cyclamen leaves curl and turn yellow
Solution: The plant lacks nutrients, so fertilize immediately. Buy special fertilizer from the flower shop, but do not over-fertilize the plant. Usually, you can bury some cooked soybeans, peanuts, soybean cakes, or spoiled steamed buns in the pot to ensure the plant does not lack nutrients.
2. cyclamen cultivation problems, stem rot, and yellow leaves
Solution: Stop watering and wait for the plant to heal and the soil to dry before watering again.
3. Yellow leaves from overwatering, flower buds withering due to lack of water, how often to water? Is it better to spray with a spray bottle or water directly into the pot?
Solution: Cyclamen can bloom twice a year if well cared for, mainly in spring and autumn. It prefers semi-shaded conditions, so do not place it in direct sunlight. In summer, when temperatures are high, cyclamen will enter dormancy. During this period, water less to keep the soil slightly moist to prevent root rot. It is best to leave one-third of the bulbous root above the soil surface when planting. Water directly into the pot, and try not to let water get on the leaves, as cyclamen leaves are round and concave in the middle, which can easily cause waterlogging and leave water stains after evaporation. Over time, poor leaf respiration can cause drying and yellowing, affecting the appearance. It is best to wipe the leaves with a soft cloth. Water when the soil is dry and water thoroughly, but do not water every day because cyclamen has bulbous roots that can store water, and too much water can cause flower buds to fall and leaves to turn yellow. Water once every three days in dry spring weather and once every five days in autumn.
4. Cyclamen leaves are curling
Light: Cyclamen should be placed near windows or on balconies with sufficient light, and the pot position should be changed frequently. Sufficient light can make the flowers more colorful and the leaves more glossy. Although cyclamen is relatively shade-tolerant, insufficient light for a long time can cause the leaves to turn yellow.
Water: Watering should be controlled, as excessive water can cause root rot. Water only when the flowers and leaves are slightly wilted. Water can be added by submerging the pot bottom, and avoid spraying too much water on the leaves.
Ventilation: Cyclamen enjoys ventilation. Smoke and polluted air can cause the petals to dry and wither, but it should not be placed directly in a draft. Temperature: A room temperature of above 5°C can keep cyclamen growing normally. A lower room temperature can prolong the flowering period, but flowering is slow; a higher room temperature speeds up flowering but shortens the flowering period.
Humidity: Humidity should be maintained at 60%-70%. Low humidity will make the flowers smaller, and high humidity can cause gray mold and other fungal diseases. Do not spray water on the petals, as it can cause them to rot.
Fertilizer: Fertilize twice a month with imported or domestic compound fertilizers, placing 5-8 pellets 2 cm deep in the soil.
5. Why are cyclamen leaves yellow and dry?
Cyclamen also turns yellow and dries mainly due to poor pot soil aeration and excessively dry soil. When the temperature is between 15-25°C, change to soil with better aeration, and water from the bottom, only watering when the soil is dry, and the water temperature should be close to the room temperature.
The above is[] about the reasons for the yellowing of cyclamen leaves, hoping it can help you in your life!
