Narcissus in the breeding process, yellow leaves appear, which must be related to the growth environment, but also with your own maintenance method is appropriate, let's see:
Narcissus is a kind of greenhouse plant planted with bulbs in autumn. It likes enough light, but it is also forbidden to direct the strong light.
When the temperature is too high, it also makes daffodils shine in the sun, and without proper shade, it is easy to make daffodils' leaves dry and yellow.
Narcissus is not cold, afraid of cold, when the temperature is too low, Narcissus is easy to frostbite, leading to yellow leaves, serious yellow death.
Therefore, the maintenance of Narcissus is to keep the temperature balanced and warm according to its growth habit.
Narcissus like humid environment, growth requirements of acid water and loose fertile acid sand soil.
When watering maintenance, only ordinary water, not pay attention to the iron content of the water, will also lead to the leaves due to lack of iron, less nutrition and gradually yellow.
The planting and maintenance of soil without proper acid soil will also lead to the lack of nutrients needed for growth and make the leaves yellow.
Although Narcissus like fertilizer, but fertilization should also have a degree
When excessive fertilization, new leaves will grow thick and uneven, while old leaves will become dry and yellow.
Do not apply fertilizer for a long time, especially applying nitrogen fertilizer, will make the soil lack of nitrogen and other nutrients, the growth of leaves will gradually wither and turn yellow.
Narcissus in the breeding process is most likely to occur by fungi and other pathogens caused by leaf spot disease, leaf spot will appear yellow spots, yellow spots will gradually expand, spread the whole leaf.
Insect pest has scale insect, red spider, etc., these insect pest can make leaf local appear wither yellow phenomenon..
The reason why Narcissus leaves turn yellow is found out, so it's easy to prevent and cure.
How to control the growth temperature of Narcissus? Don't worry. When it's hot and hot, you just need to move narcissus to a well ventilated and cool place in time to avoid strong light. Will make the leaves gradually return to normal.
When planting Narcissus, we must choose acid soil to ensure the nutrition needed for growth. During the growth of Narcissus, we should pour alum fertilizer water. In this way, the leaves will not be yellow due to iron deficiency.
Narcissus maintenance must be on time according to the amount of fertilizer, if fertilization is too much, you can try to change the water, so that the excess fertilizer loss, or immediately pour the basin, wash the ball root with water.
If you don't apply fertilizer for a long time and the leaves turn yellow, you can use the new culture water to apply the thin and rotten liquid fertilizer or the compound flower fertilizer. In this way, you can save the yellow leaves and grow again
When the emergence of diseases and insect pests is the most effective way is to spray medicine, will completely eliminate diseases and insect pests.
