What s going on with the daffodil leaves turning yellow?

After flowering, the leaves will fade, and if they turn yellow before flowering, it means that there is a problem with the water quality.

What's going on with the yellowing of daffodil leaves, as follows:

1. The temperature is too low.

The yellow leaves of the daffodils may be due to the low temperature. Daffodils have poor cold tolerance, and when the temperature drops in winter, the plants will suffer from frost damage and show symptoms of yellow leaves, so keep the daffodils indoors and maintain the ambient temperature at about 10 degrees Celsius, so that the plants can grow normally.

2. Soil alkalization.

The yellow leaves of the daffodils may be due to the alkalizing of the ten soils. Daffodils are suitable for growing in acidic soil, and alkalinization of the soil will lead to poor plant growth, so it is necessary to mix fermented orange peel or vinegar solution into the soil to improve the acidity of the soil and restore the growth of daffodils.

3. Insufficient nutrients.

The yellow leaves of daffodils may be due to nutrient deficiencies. Daffodils have a greater demand for nutrients, and too little fertilization during breeding will lead to malnutrition and yellowing of plants, so you can provide fertilizer for daffodils once a week, and use absorbed ammonia, phosphorus and potassium mixed fertilizer to make the plants grow better.

4. Post-management.

Daffodils are light-loving plants, suitable for growing in a sunny environment, and should be placed in a sunny environment when cultivating to maintain the emerald green leaves. However, if the afternoon light is too strong, the daffodils should be placed in a astigmatism environment to avoid strong light affecting the plants.

Narcissus grows in the environment:

Narcissus is an autumn bulb greenhouse flower, which likes full sunlight, has tenacious vitality, can tolerate semi-shade, and is not cold-tolerant. 7 In August, the leaves are dormant, and the flower buds are differentiated at the growth point of the bulb in the dormant period, which has the physiological characteristics of autumn and winter growth, early spring flowering, and summer dormancy. Narcissus likes light, water and fertilizer, is suitable for warm, humid climatic conditions, and prefers fertile sandy soils.

It prefers coolness in the early stage of growth, slightly hardy in the middle stage, and warm in the late stage. Therefore, it is required to have no severe cold in winter and no heat in summer, and rainy climate and environment in spring and autumn.

(1) Specific reasons: There are more requirements for nutrients in the growth period. If the amount of fertilizer is too small for a long time, or if the pot has not been changed for a long time, there is a serious lack of nutrients, and the leaves are prone to yellowing. This mainly refers to the element nitrogen.

2) Solution: Timely supplement some nitrogen-containing fertilizers. However, don't use too much at once, and don't use too much.

1) Specific reasons: more common in winter. If the temperature is too low, the plants will be damaged by frost, and the leaves will easily turn yellow, and in severe cases, they will wither and die.

2) Solution: Adjust the room temperature in time after discovery, or move to a warmer place.

(1) Specific reason: If there is a lack of iron in the watering water, the leaves will also turn yellow.

2) Solution: Supplement some soluble iron, pour some alum fertilizer water, etc.

1) Specific reasons: Plants have a large demand for light, especially in winter. If you are shaded for a long time and lack of light, the branches and leaves will turn yellow.

2) Solution: Replenish the light immediately after discovering the yellow leaves, and ensure more than six hours of light every day. However, it must also be blocked when encountering too strong light.

(1) Specific reasons: no pruning for a long time, too many branches and leaves, poor light transmission, insufficient nutrition, easy to make the leaves yellow.

2) Solution: Prune the branches and leaves in time if they are too lush, and it is best to prune them regularly. In addition, some fertilizers can be appropriately supplemented.

Causes of yellowing of daffodils leaves.

In the process of breeding, the leaves are yellowing, which must be related to the growth environment, and whether your own maintenance methods are appropriate

Reason 1: The temperature is unreasonable.

Narcissus is an autumn bulb greenhouse plant that prefers plenty of light, but also taboos direct sunlight.

When the temperature is too hot, the daffodils are also exposed to the sun, and without proper shading, it is easy for the daffodils to wither and turn yellow.

Narcissus is not cold-tolerant, afraid of cold, when the temperature is too low, daffodils are easy to frostbite, resulting in yellowing of the leaves, which will dry to death in severe cases.

Therefore, the maintenance of narcissus must be based on its growth habits, and the temperature must be kept balanced and warm.

Reason 2: Improper soil and water.

Narcissus prefers moist environments and grows on acidic water and loose, fertile acidic sandy soils.

When watering and maintaining, only ordinary water is used, and the iron content in the water is not paid attention to, which will also cause the leaves to gradually turn yellow due to iron deficiency and lack of nutrients.

Soil cultivation and maintenance without suitable acidic soil can also lead to a lack of nutrients for growth and yellowing of leaves.

Reason 3: Excessive fertilization or no fertilization for a long time.

Although narcissus prefers fertilizer, it should also be fertilized in moderation.

When fertilization is excessive, new leaves grow thick and uneven, while old leaves dry out and yellow. Cautious branch swimming.

If you don't apply fertilizer during the long and wide sales time, especially nitrogen fertilizer, the soil will lack nutrients such as nitrogen, and the leaves will gradually wither and turn yellow.

Reason 4: Pests and diseases.

Narcissus is most likely to have leaf spot disease caused by fungi and other pathogens in the breeding process, which will cause yellow spots on the leaves, and the yellow spots will gradually expand and spread throughout the leaves.

Insect pests such as scale insects, red spiders, etc., these insect pests will cause the leaves to appear yellowing locally.

Yellowing of daffodil leaves.

If you find out the reason for the yellowing of daffodils leaves, it will be easy to control!

First: control the growth temperature.

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

Second: pay attention to the choice of watering and soil.

When planting daffodils, it is necessary to choose acidic soil to ensure the nutrients needed for growth, and to water alum fertilizer during the growth period of daffodils. This way, the leaves will not turn yellow due to iron deficiency.

Third: apply fertilizer on time and in the right amount.

If you apply too much fertilizer, you can try changing the water to let the excess fertilizer go away, or immediately pour the pot and rinse the bulbous with clean water.

If the leaves turn yellow because they have not been fertilized for a long time, you can use new culture water to apply thin rotting liquid fertilizer or compound flower fertilizer. This way, you can save the yellow leaves and grow them back.

Fourth: pest control.

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