The cause and solution of cyclamen leaves yellowing

We all know that too much cyclamen water will lead to root rot, which is caused by too much water that the root can not absorb oxygen, so what if the cyclamen leaves turn yellow? What's going on? Next, let the editor explain to you the causes and solutions of the yellowing of cyclamen leaves.

The reason for the yellowing of cyclamen leaves

1. Long-term de-fertilization: there is no application of nitrogen fertilizer or change of water for a long time, and there is a lack of nitrogen and other nutrient elements in the water, resulting in thin and yellow branches and leaves. It is necessary to change into new culture water in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer.

2. Excessive fertilization: if there is too much fertilization, the new leaves will be thickened, and the old leaves will be rugged, and the dry tips of the old leaves will fall off. You should immediately stop fertilization, increase the amount of water exchange, make the fertilizer lose, or immediately pour the pot, rinse the bulb root with water and then replant it into the basin.

3. Hot and high temperature: if you put the daffodils in a high temperature and let the strong light shine directly, it is very easy to cause the leaf tip and edge of the young leaves to scorch, or the leaves yellow to fall off. Move to a well-ventilated shady place in time.

4. Excessive shading: if the daffodils are placed in shade or in places where there is not enough light for a long time, it will cause the branches and leaves to turn yellow.

5. Alkalinity of soil and water: if there is a lack of soluble iron and other elements that can be absorbed by it in the growth environment, the leaves will gradually turn yellow. Acid soil and water should be selected when planting, and alum and fertilizer water should be often irrigated during the growth period.

6. Lack of ventilation: if too much nitrogen fertilizer is applied, the branches and leaves will grow luxuriantly, coupled with long-term unpruned, resulting in insufficient light in the inner chamber branches and leaves, which is easy to cause leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent.

7, air drying: when the indoor air is too dry, daffodils often appear leaf tip drying or leaf edge scorching and other phenomena. Attention should be paid to water spraying, plastic film cover and other methods to increase air humidity.

The solution of cyclamen leaves yellowing

1. Cyclamen leaves are curly and yellowing

[solution] lack of nutrition, pay close attention to fertilization, to the florist to buy special fertilizer can not be too much to supplement the nutrition of flowers, usually can bury a small amount of cooked soybeans, cooked peanuts in the pot. Bean cakes, changed steamed buns, etc., so as not to worry about lack of nutrition

2. Cyclamen cultivation problems, flower stems rot, flowers and leaves yellowing

[solution] too much water. Stop watering until it heals and the soil dries.

3. The leaves turn yellow when watered, but the buds that just grow in less water are withered. Would it be better to water them once every few days? It's better to spray it with a spray can or pour it directly into the basin.

[solution] cyclamen flowers can bloom two seasons a year, mainly in spring and autumn, so don't shine directly in the sun. If the temperature is high in summer, cyclamen will be dormant. Watering as little as possible during dormancy to keep the soil moist is enough to prevent the roots from rotting because of too much moisture. When planting, it is best to expose the bulbous roots of flowers to 1/3 of the soil surface for direct watering. Try not to get wet on the leaves in the flowerpot, because the leaves of cyclamen are round, concave in the middle, easy to store water, not good enough to leave water stains after evaporation, leave water stains for a long time, and the leaves are easy to dry and yellow. it is best to use a soft cloth to wipe and water once and not every day, because cyclamen is a spherical root that has the function of water storage. It is easy to produce buds and leaves yellowing, spring, dry and dry for three days, once in autumn and about five days in autumn.

4. The leaves of cyclamen are curled

① lighting: cyclamen should be placed in windows, balconies and other places with sufficient light, and often change the position of flowerpots. Plenty of light can make the flowers more beautiful and the leaves more shiny. Although cyclamen belongs to the shade-tolerant Primulaceae, it is easy to yellowing leaves due to lack of light for a long time.

② moisture: watering should be properly controlled, too much water will cause rotten roots, but wait for flowers and leaves to wilt slightly before watering, watering can be soaked at the bottom of the basin, do not sprinkle too much water on the leaf surface.

③ ventilation: cyclamen likes ventilation, smoke and dirty air will make the petals dry and wither, but they can not be placed directly in the tuyere. Temperature: room temperature above 5 ℃ can make cyclamen grow normally. When the room temperature is low, cyclamen can keep the florescence for a long time, but the flowering is slow; when the room temperature is high, the flowering is fast, but the flowering period is short.

④ humidity: humidity should be kept at 60%, 70%. Too little humidity will make flowers smaller, too much humidity will cause petals, leaves to appear gray mold and other fungal venereal diseases. It is strictly forbidden to spray water on the petals, otherwise they will rot.

⑤ fertilizer: fertilize twice a month, can use imported or domestic compound fertilizer, each application of 5-8 grains, placed in the depth of 2 cm of the substrate.

5. Cyclamen leaves are yellow and withered

Cyclamen leaves yellowing and drying up are mainly caused by the poor air permeability of the basin soil and the over-drying of the basin soil. The soil with better permeability can be changed when the temperature is 15-25 degrees, and the water should be fed from the bottom, and the basin soil can be watered only when the basin soil is dry, and the water temperature is close to room temperature.
