Anonymous users2024-02-12In 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: Unreasonable temperature Narcissus is a kind of greenhouse plant with autumn bulbs, which likes sufficient 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 a moist environment and requires acidic water and loose and fertile acidic sandy soils to grow.
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 likes fertilizers, fertilization should also be done in moderation.
When fertilization is excessive, new leaves grow thick and uneven, while old leaves dry out and yellow.
If you don't apply fertilizer for a long time, especially nitrogen fertilizer, the soil will lack nutrients such as nitrogen, and the leaves will gradually wilt and turn yellow.
Reason 4: The appearance of pests and diseases Narcissus is most likely to have leaf spot disease caused by fungi and other pathogens in the breeding process, leaf spot disease will cause yellow spots on the leaves, and the yellow spots will gradually expand and spread throughout the leaves.
Insect pests include scale insects, red spiders, etc., which will cause the leaves to appear yellowing locally.
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 selection of watering and soil When planting daffodils, acidic soil must be selected to ensure the nutrients needed for growth, and alum fertilizer should be watered during the growth period of daffodils. This way, the leaves will not turn yellow due to iron deficiency.
Third: Fertilize on time and in the amount When maintaining daffodils, you must apply fertilizer on time and in the right amount, if you apply too much fertilizer, you can try to change the water to let the excess fertilizer lose away, or immediately pour the pot and rinse the bulb with 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 occur, the most effective way is to spray drugs to completely eliminate pests and diseases.
