Narcissus, a kind of lovely flower, not only has beautiful shape and bright color, but also exudes charming fragrance, so it is deeply welcomed and loved by everyone. However, in the process of breeding, due to various reasons, there will be symptoms of leaves yellowing, then how to do daffodils leaves yellowing? Here are the reasons and solutions for the yellowing of the leaves of 7 kinds of daffodils carefully arranged by the editor. Let's go and have a look!

First, what if the daffodil leaves turn yellow? find the reason.

In the culture method of daffodils, we introduce the requirements of daffodils on soil, light, water and so on. once we can not meet it, there will be symptoms of yellowing leaves. At this time, flower friends do not worry, but should carefully find the cause, to see what caused it. Here are seven causes and solutions for the yellowing of daffodil leaves. Let's move on.

Second, the causes and solutions of the yellowing of daffodils leaves.

1. Environmental change

On the Internet, many flower friends responded that the daffodils they bought were good at the beginning, but they didn't keep them for a long time, and the leaves turned yellow. they wanted to know why the daffodils leaves turned yellow. In this regard, the editor suggests that we first consider the problem of environmental changes, because the growth environment changes greatly, daffodils may not be able to adapt, resulting in yellowing symptoms of leaves.

Solution: when buying daffodils, you can communicate with the shop owner to understand its growth environment, and then buy it back to keep the environment the best. Once the daffodils leaves turn yellow caused by environmental changes, flower friends should change the environment appropriately to let the daffodils gradually adapt. I believe it will not take long to recover.

2. Soil is slightly alkaline.

The most important thing for potted daffodils is the soil. Once the soil is selected, the problem is very serious. Daffodils like loose, fertile, slightly acidic soil, so if the soil is alkaline, it will cause plant growth and cause daffodil leaves to turn yellow. Or it is called tap water for a long time, resulting in slow dilution of the soil, resulting in a slightly alkaline situation.

Solution: if it is a soil problem, flower friends should immediately change the pot soil and choose loose and fertile acid sand soil. Then after a period of maintenance, the daffodils will glow again.

3. Improper watering

To say that the daffodil leaves turn yellow, the first thing we have to think of is watering. It is understood that daffodils like a humid environment and are required to pour acidic water. So when flower friends pour pots of soil and water on Narcissus, because there is little iron in the water, the leaves will gradually turn yellow due to lack of iron and less nutrition.

Solution: it is found that the leaves of daffodils turn yellow caused by watering, and flower friends should call more iron-rich water. In order to ensure the nutrition needed for growth, it is necessary to pour more alum and fertiliser during the growth of daffodils, so that the leaves will not turn yellow because of iron deficiency.

4. The temperature is too low

In addition to the above, improper temperature is also one of the reasons for the yellowing of daffodil leaves. It is understood that Narcissus is not cold-resistant, and afraid of cold, in the case of too low temperature, it is easy to get frostbite, resulting in symptoms of yellowing leaves.

Solution: when the temperature is low in winter, the room temperature should be adjusted in time, and the air conditioner can be turned on if possible. Before that, we must understand the growth habits of daffodils and keep the temperature balanced.

5. The light is too strong

In the flower world, almost all flowers need light, and daffodils are no exception. However, although daffodils like light, they taboo direct glare. Once the daffodils are exposed to the summer sun, their leaves turn yellow.

Solution: in the summer sun, flower friends should move the daffodils to a well-ventilated and cool place to avoid strong light, so that after a period of maintenance, the leaves will gradually return to normal.

6. Excessive fertilization or no fertilization for a long time

When it comes to the reasons for the yellowing of daffodil leaves, fertilization is also needed. Although daffodils like fertilizer, but once fertilized too much, it will cause fertilizer damage, resulting in withered and yellow old leaves; but if there is no fertilization for a long time, especially without nitrogen fertilizer, the soil will lack nitrogen and other nutrients, and the leaves will gradually wither and turn yellow.

Solution: when fertilizing too much, we should immediately stop fertilizing, increase the amount of water, so that fertilizer loss. Or crisp, directly change the pot soil, let the daffodils dry up; when the lack of fertilizer, flower friends can apply compound flower fertilizer, after a period of time, your daffodils will recover.

7. Emergence of diseases and insect pests

If the above points can be excluded, then the yellowing of daffodil leaves is caused by diseases and insect pests. Because when Narcissus suffers from leaf spot disease, it is easy to cause local necrosis of the leaves, resulting in symptoms of withered and yellow leaves; and when attacked by shell insects, red spiders and other pests, these pests will make the leaves of Narcissus partially withered and yellow, and even the whole leaves wither and fall off.

Solution: when there are diseases and insect pests, the relevant agents should be sprayed to cure the disease and completely eliminate the insect pests. As for what medicine should be sprayed in the end, there is a specific introduction in the prevention and control of daffodils diseases and insect pests, so I won't say much here.

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.

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

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.
