Yellow leaves of Cyclamen: Causes and treatment

Cyclamen likes light but is afraid of strong light. It's OK to have weak light every day. If it is exposed to the sun, it will cause the leaves to turn yellow. When the flowers of Cyclamen blossom more and more lightly, it is related to the lack of light and insufficient fertilization. Fertilization must be professional fertilizer, otherwise, it will also cause the leaves to turn yellow. Now let's specifically analyze and solve the problem of the yellow leaves of Cyclamen. seven possible ways for Cyclamen to grow yellow leaves in pot 1. Long term fertilization:

For a long time, there was no nitrogen application or water exchange, and the lack of nitrogen and other nutrients in the water resulted in thin and yellow branches and leaves. It is necessary to change into new culture water in time to gradually increase the application of thin and mature liquid fertilizer or compound flower fertilizer.

2. Excessive fertilization:

If the fertilizer is applied too much, the new leaves will be thick and uneven, and the old leaves will be scorched and yellow, so the fertilizer should be stopped immediately, the water change should be increased, so that the fertilizer will be lost, or the pot should be poured immediately, and the ball root should be washed with water and then replanted in the pot.

3. Hot and high temperature:

If Narcissus is placed in a high temperature place for direct sunlight, it is easy to cause the tip and edge of young leaves to scorch, or yellow leaves to fall off. Move to a cool place with good ventilation in time.

4. Excessive shade:

If you put Narcissus in shade or lack of light for a long time, it will cause yellow branches and leaves.

5. Alkali of water and soil:

The leaves will turn yellow gradually if there is no soluble iron and other elements that can be absorbed by them in the growing environment. Acid soil and water shall be selected for planting, and alum fertilizer water shall be frequently poured during growth.

6. Airtight:

If too much nitrogen fertilizer is applied, the branches and leaves will grow in exuberance, and they will not be pruned for a long time, resulting in the lack of light in the branches and leaves in the bore, which will easily cause the leaves to turn yellow and fall off. We should apply fertilizer reasonably and strengthen pruning to make it ventilated and transparent.

7. Air drying:

When the indoor air is too dry, Narcissus often appears the phenomenon of withered leaf tip or scorched leaf edge. Attention should be paid to water spray, plastic film cover and other methods to increase air humidity. pink Cyclamen leaves turn yellow specific case 1. Cyclamen leaves curl yellow solution: lack of nutrition, hurry to apply fertilizer, buy special fertilizer to Florist not too much to supplement nutrition for flowers, usually a small amount can be buried in the basin with some ripe soybeans, ripe peas and raw rice. Bean cake, changed quality of steamed bread and so on, so we won't worry about lack of nutrition. 2. The solution to the rotten stems and yellow leaves of Cyclamen: more water. Stop watering and wait for the soil to heal and dry before watering. 3. The solution to the problem that the leaves turn yellow when watered more and the buds just grow dry when watered less: in summer, when the temperature is high, cyclamen will go to sleep. During dormancy, water as little as possible and keep the soil moist, so as to prevent the root from rotting due to excessive water. It is better to expose the spherical root of the flower to one third of the soil surface when planting. When watering, directly pour it into the flowerpot, and try not to touch the leaves with water, because the leaves of Cyclamen are round and concave in the middle, which is easy to store water, so it is not good to leave water stains after water evaporation. For a long time, the leaves will be dry and yellow easily if they are not breathing well, which will affect the view. It is better to wipe them with a soft cloth. When watering, you need to see that it is wet and dry once, and you can't water it every day, because Cyclamen has the function of storing water in spherical roots. If you pour more water, it is easy to produce flower buds. The leaves turn yellow, dry in spring, water once in three days, and water once in five days in autumn.

4. The leaves are yellow and dry

Solution: Cyclamen is also yellow and dry mainly due to poor permeability of basin soil and over drying of basin soil. When the temperature is 15-25 ℃, the soil with good permeability can be replaced. Water should be supplied from the bottom, and the basin soil can be watered only when it is dry, and the water temperature is close to the room temperature. Cyclamen maintenance (necessary basic knowledge) 1. Lighting: Cyclamen should be placed in windows, balconies and other places with sufficient lighting, and often change the position of flower pots. Sufficient light can make flowers more gorgeous and leaves more glossy. Although Cyclamen belongs to Primula family, it is easy to make its leaves yellow due to lack of light for a long time. 2. Water content: watering should be controlled properly. Excessive water content will cause rotten roots. Watering can be done when flowers and leaves are slightly wilted. Watering can be done by means of basin bottom soaking instead of too much water on the leaves. 3. Ventilation: Cyclamen likes to ventilate. Smoke and dirty air will dry and wither the petals, but it can't be placed directly at the air outlet. 4. Temperature: room temperature above 5 ℃ can make Cyclamen grow normally. When the room temperature is low, the Cyclamen can maintain a longer flowering period, but the flowering is slow; when the room temperature is high, the flowering is fast, but the flowering period is short. 5. Humidity: the humidity shall be kept at 60% - 70%. Too low humidity will make flowers smaller, too high humidity will make petals and leaves appear gray mold and other fungal diseases. Do not spray water on the petals, otherwise the petals will rot. 6. Fertilizer: apply fertilizer twice a month, using imported or domestic compound fertilizer, 5-8 grains each time, placed in the depth of 2cm.
