The culture method of daffodils what if the leaves turn yellow?

Daffodils grow very good-looking, wicker-shaped leaves, but also blooming flowers, it is very lovely, there is a very happy feeling, how to cultivate daffodils? What if there are yellow leaves in the process of breeding? Let's take a look at the Women's Network:

Culture methods of daffodils:

1. The method of hydroponic culture of daffodils before aquaculture, you should first peel off the dry brown scale leaves in the outer layer of the bulb, remove the root mud and the brown rotten root at the base (be careful not to touch the new white root), wash the surface, stand upright in a shallow basin without drainage holes, add water to about 1 cm under the daffodil's head, put it in a cool place, wait for the bulb to grow root, and then put it in the sun. Hydroponic daffodils had better change water every day, on the one hand, to prevent water deterioration and pollution caused by rotten roots, on the other hand, change water every day, clean water grows out of the roots are also white and beautiful. When changing water, use sun-dried tap water. Avoid too much water and soak to one and a half of the flower heads. Before flowering, the water can be changed to 2mi every 3 days.

The growth of daffodils requires sufficient sunshine; the appropriate temperature is about 15 degrees. In order to make the daffodils grow strong, you should get more sun on the balcony during the day. Daffodils like sunshine best. Without sunshine, it is difficult for daffodils to blossom. After the sun comes out, the daffodils are removed from the outdoors, illuminated directly, and then moved back into the house when the sun is insufficient. 2. Soil cultivation of daffodils requires loose humus soil. Before planting, you should peel off the dry bulb of the daffodil head and scrape off the old root, add humus soil to 3 cm along the edge of the basin, and firm the humus soil, then place the daffodil bulb in the basin, continue to add soil about 1 cm, then water thoroughly, and then put the flowerpot in a cool place. 5 days later, after the bulb plate grows roots, put the flowerpot in a sunny place for breeding. Soil watering should pay attention to dry and wet, that is, the soil is not dry or watered, once watered until the pot bottom is leaking, the watering time should be chosen in the morning and evening, otherwise it will destroy the root growth. 3. The method of sand cultivation of daffodils is best to use clean fine sand, and the basin is also required to be a well-breathable tile basin. Before planting, put the sand into the basin and install it along the edge of the basin. Then the daffodil head which is stripped off the old stem and the old root is located. In the flowerpot filled with fine sand, add about 1 cm of sand, so that the lower stem of the daffodil head is buried in about 1 cm of sand. Then pour through the water and put it in the shade. Put it in the sun after 5 days until it blossoms. Planting daffodils with sand should be watered thoroughly every day. Not watering in time will cause water shortage and affect the root growth of flowers. Watering is also required to be arranged in the morning and evening.

What if the leaves of daffodils turn yellow?

1. Improper fertilization, long-term lack of fertilizer: no application of nitrogen fertilizer or no change of water, lack of nitrogen and other nutrient elements in water, resulting in thin and yellow leaves and branches. It is necessary to change into new culture water in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer. B, 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. C, pesticide stimulation: excessive concentration of pesticides is used in the prevention and control of diseases and insect pests, or polluted by toxic gases in the atmosphere, or cold water is suddenly irrigated when the temperature is high, which can easily cause local yellowing and scorching of the leaf tip or leaf surface, or even death of the whole plant. Therefore, we should pay attention to the rational use of pesticides and try to eliminate air pollution sources. Avoid watering flowers with cold water around noon in midsummer.

2. The temperature is not good

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

B, the temperature is too low: the winter temperature is too low, and the daffodils suffer from cold damage, which leads to the yellowing of the leaves and death in severe cases. If the room temperature is too high, the transpiration of the plant is too high, and the root water and nutrients are in short supply, the leaves will turn yellow. Please pay attention to adjust the room temperature in time. 3. Water and soil is not suitable for a, lack of iron in the water: due to the lack of soluble iron and other elements that can be absorbed by the water, 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. B, 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.

4. Lack of light if the daffodils are placed in shaded places or places with insufficient light for a long time, excessive shading will lead to yellowing of branches and leaves. As long as you have 6 hours of light every day, you can grow normally. If the light is not enough, the leaves are easy to grow, and the blossoms are few or not; if the light is too strong, it is also disadvantageous to growth. 5. If the branches and leaves of daffodils grow luxuriantly for a long time without pruning, and they are not well-ventilated for a long time, the light of the branches and leaves of the inner chamber is insufficient, and it is easy to cause the leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent.

6. Disease and insect damage leaf spot disease caused by fungi and other bacteria, it is easy to cause local necrosis of the leaves, yellow spots or patches appear, the whole leaves wither and fall off seriously, and the leaves are mottled with yellow and green after being infected by mosaic virus; suffering from shell insects, red spiders and other damage, the leaves will also become local yellow, and even the whole leaves will wither and fall off. All should be sprayed in time.

Raising daffodils also takes some effort to raise them well. Once the leaves turn yellow, it can be solved according to the above method.

How to deal with the yellowing of daffodil leaves? how to treat the yellowing of daffodils leaves?

Narcissus habits, daffodils for autumn bulb root greenhouse flowers, like sufficient sunshine, tenacious vitality, can withstand semi-shade, not cold-resistant. The fallen leaves were dormant from July to August, and the flower buds differentiated at the growing point of the bulb during the dormant period, with the physiological characteristics of autumn and winter growth, early spring flowering and summer dormancy. Narcissus like light, water, fertilizer, suitable for warm, humid climatic conditions, like fertile sandy soil. It likes cool in the early stage of growth, slightly hardy in the middle stage and warm in the later stage. Therefore, it requires a climate environment with no severe cold in winter, no heat in summer and rainy in spring and autumn.

During the cultivation of daffodils, there is a yellowing of leaves, which must have something to do with the growing environment and whether your own maintenance methods are proper or not. let's take a look:

Analysis on the causes of yellowing of Narcissus leaves 1. Unreasonable temperature

Narcissus is a kind of greenhouse plant with bulbs planted in autumn, which likes plenty of light, but also taboos strong light. When the temperature is too hot, but also let the daffodils shine in the sun, and without proper shade, it is easy to make the daffodils leaves withered and yellowed. Daffodils are not cold-resistant and afraid of cold. When the temperature is too low, daffodils are prone to frostbite, resulting in yellowing of leaves, serious yellowing and death. Therefore, the maintenance of daffodils must be in accordance with its growth habits, to keep the temperature balanced and warm.

2. Inappropriate soil and water

Daffodils like a humid environment, and their growth requires acidic water and loose and fertile acidic sandy soil. When watering and curing, only use ordinary water, and do not pay attention to the iron content in the water, it will also cause the leaves to turn yellow gradually due to lack of iron and less nutrition.

The planting and maintenance of the soil does not use suitable acidic soil, which can also lead to the lack of nutrients for growth and yellowing of leaves.

3. Excessive fertilization or no fertilization for a long time

Although daffodils like fertilizer, there should be a certain degree of fertilization. when excessive fertilization is applied, the new leaves will grow thick and uneven, while the old leaves will dry and turn yellow.

No fertilization for a long time, especially the application of nitrogen fertilizer, will make the soil lack of nitrogen and other nutrients, and the leaves will gradually wither and turn yellow.

4. Emergence of diseases and insect pests

Daffodils are most prone to leaf spot disease caused by fungi and other bacteria in the process of culture. Leaf spot disease will make the leaves appear yellow spots, which will gradually expand and spread the whole leaf.

Insect pests are shell insects, red spiders and so on, these pests will cause local withering and yellowing of leaves.

How to deal with the yellowing of daffodil leaves 1. Control the growth temperature

How to control the growth temperature of daffodils? don't worry, when it is hot and hot, you only need to move the daffodils to a well-ventilated and cool place to avoid strong light. The leaves will gradually return to normal.

2. Pay attention to watering and soil selection.

When planting daffodils, we must choose acidic soil to ensure the nutrition needed for growth, and irrigate alum and fertile water during the growth of daffodils. In this way, the leaves will not turn yellow because of lack of iron.

3. Apply fertilizer on time and according to quantity

Daffodils must be maintained on time and according to the amount of fertilizer, if too much fertilizer, you can try to change water, let the excess fertilizer loss, or immediately pour the basin, rinse the bulb with clean water.

If the leaves turn yellow because they have not been fertilized for a long time, you can use the new culture water to apply rarefied liquid fertilizer or compound flower fertilizer. In this way, you can save the yellow leaves and grow again.

4. When diseases and insect pests appear, the most effective way is to spray medicine to completely eliminate the diseases and insect pests.

How to do daffodils leaves yellowing? four rescue methods.

Daffodils do not have the strong fragrance of jasmine, nor are they as flirtatious and graceful as peonies, nor are they as tenacious as plum blossoms. however, daffodils maintain their own freshness and elegance, and their appearance is not worldly. Daffodils generally grow in loose and breathable sand, and daffodils need more water for their growth than ordinary flowers, especially in the peak period of growth. Otherwise, the leaves will turn yellow easily. The following analysis of daffodils leaves yellowing of the six reasons and what to do.

Reasons for yellowing of daffodils leaves 1. Improper fertilization leads to yellowing of leaves.

A) long-term lack of fertilizer: no application of nitrogen fertilizer or no change of water, lack of nutrients such as nitrogen 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.

B) excessive fertilization: if there is too much fertilization, the new leaves will be thickened, and the dry tips of 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.

C) Pesticide stimulation: excessive concentration of pesticides in the prevention and control of diseases and insect pests, or pollution by toxic gases in the atmosphere, or sudden watering of cold water when the temperature is high, all of which can easily cause local yellowing and scorching of the leaf tip or leaf surface, or even death of the whole plant. Therefore, we should pay attention to the rational use of pesticides and try to eliminate air pollution sources. Avoid watering flowers with cold water around noon in midsummer.

2. Poor temperature leads to yellowing of leaves.

A) Hot and high temperature: if the daffodils are placed in a high temperature and let the strong light shine directly, it is very easy to cause scorch on the tip and edge of young leaves, or leaf yellow shedding. Move to a well-ventilated shady place in time.

B) the temperature is too low: when the winter temperature is too low, the daffodils suffer from cold damage, which leads to the yellowing of the leaves and death in severe cases. If the room temperature is too high, the transpiration of the plant is too high, and the root water and nutrients are in short supply, the leaves will turn yellow. Please pay attention to adjust the room temperature in time.

3. Soil and water should not cause the leaves to turn yellow.

A) lack of iron in water: due to the lack of soluble iron and other elements that can be absorbed by the water, 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.

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

If the light is not enough, the leaves are easy to grow, and the blossoms are few or not; if the light is too strong, it is also disadvantageous to growth.

5. Long-term unpruned

If the branches and leaves of Narcissus grow luxuriantly, coupled with the long-term unpruned, not ventilated, resulting in insufficient light of the inner branches and leaves, it is easy to cause the leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent.

6. diseases and insect pests lead to yellowing of leaves

The leaf spot disease of daffodils caused by fungi and other bacteria is easy to cause local necrosis of the leaves, yellow spots or patches appear, the whole leaves wither and fall off seriously, and the leaves are mottled with yellow and green after being infected by mosaic virus; suffering from shell insects, red spiders and other damage, the leaves will also become local yellow, and even the whole leaves will wither and fall off.
