Cyclamen leaves yellow causes and solutions Details

Growing flowers is a relaxing and enjoyable thing, but it is also a knowledge. Let's take a look at the causes and solutions of cyclamen leaves yellowing.

Detailed introduction of the causes and solutions of cyclamen leaves yellowing

Seven causes of cyclamen leaves yellowing

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. Soil and water bias: if there is a lack of soluble iron and other elements that can be absorbed by it, 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 spraying water, covering plastic film cover and other methods to increase air humidity.

Specific cases 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 a small number of pots can bury some cooked soybeans, cooked peanuts. Bean cakes, changed steamed buns, etc., so as not to worry about lack of nutrition.

2. The stems of cyclamen are rotten and the leaves are yellow.

Solution: too much water. Stop watering until it heals and the soil dries.

3. If you water too much, the leaves turn yellow, but if you water less, the buds that just grow are withered.

Solution: when the summer temperature is high, cyclamen will go dormant. Watering as little as possible during dormancy, just keep the soil moist to prevent the roots from rotting away due to too much water. When planting, it is advisable to expose the bulbous roots of flowers to 1/3 of the soil. When watering, water directly in the flowerpot, flowers and leaves as far as possible do not touch water, because cyclamen leaves are round and concave in the middle, it is easy to store water, it is not good to leave water marks after evaporation. For a long time, the foliar breathing is not smooth, it is easy to dry and yellowing, affecting the ornamental, it is best to wipe with a soft cloth. When watering, you should see it dry and wet once, and you can't water it every day, because cyclamen has the function of storing water and watering more water, it is easy to produce flower buds. The leaves turn yellow and dry every three days in spring and once every five days in autumn.

4. The leaves are yellow and dry

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