Poinsettia, this is a kind of plant that many people like to raise, that is, they have to look red in order to look good. As a result, their own home-raised poinsettias have yellow leaves, not only yellow leaves, but also flowers that are not red. I am so angry. Let's take a look at how the poinsettia leaves turn yellow. What if a poinsettia is not red?

What if the leaves of a poinsettia turn yellow:

1. Control watering

Most of the yellow leaf problems are caused by too much watering, and the stagnant water in the basin makes it difficult for the roots of poinsettia to get enough oxygen. Therefore, from the moment the yellow leaves are found, reduce the amount of water until you see the basin soil turn white and then water it.

2. Cut off the rotten root

Poinsettia and yellow leaves are generally only superficial, and the decay of its roots is the internal cause. Therefore, the root system of poinsettia should be properly turned out for observation. If rotten roots are found, they should be cut off in time to prevent bacteria from continuing to infect other parts.

3. Pry up the soil

Pry up the basin soil with a small shovel to increase the evaporation of water and the infiltration of oxygen, which is absolutely beneficial to the improvement of the symptoms of poinsettia yellow leaves.

4. Strengthen the lighting

Although poinsettia is a short-day plant, if there is no light for a long time, the leaves not only will not remain green, but also easy to yellowing. The right thing to do is to move the pot to a place with plenty of light immediately to promote photosynthesis.

5. Increase the room temperature

Keeping the room temperature above 15 ℃ in winter and increasing the heating will be beneficial to the growth of poinsettia and the symptoms of yellow leaves should be greatly alleviated.

What if a poinsettia is not red?

1. Lack of light for a long time

Solution: lack of light, poinsettia is not only not conducive to growth, but also easy to get sick, so can not see red bracts or small problems, there are no yellow leaves, rotten roots and other symptoms is lucky. Hurry up to move your poinsettia to a sunny place. I believe its red bracts will appear soon.

2. Not yet in bloom

Solution: the flowering period of poinsettia can last from December to February of the following year. If its flowering period has not yet arrived, that is, it is in the growing period, the green leaves may continue to sprout, and flower friends will naturally see less red bracts.

3. Insufficient fertilization

Solution: insufficient fertilization is fatal to the growth of poinsettia. Poinsettias that lack of fertilizer tend to be short and thin. Is Mamanet right? Hurry to give it some special plant fertilizer, which is good for its germination and growth to eat red bracts.

The treatment of yellowing leaves and non-red flowers of poinsettia is introduced here, so hurry up to raise one at home.

The reason for the yellowing of poinsettia leaves what to do

It is normal to raise poinsettia, green or red leaves. But the yellowing of its leaves means something is wrong. What is the reason why the leaves of poinsettia turn yellow? What if the leaves of a poinsettia turn yellow?

The reason for the yellowing of poinsettia leaves: the basin soil is too dry

In the breeding of poinsettia, if there is too little watering, or the weather is dry and the light is strong, it is easy to cause the leaves to turn yellow. Basically, this is related to air humidity. In hot summer or autumn, poinsettias need to be placed when there is plenty of sunshine, but it is best to pour enough water, and need to replenish water in time. Spray water to improve air humidity.

The reason for the yellowing of poinsettia leaves: it is not timely to change the pot.

When cultivating poinsettia, the first planting is generally a relatively small flowerpot, but after a period of time, the plant will grow slowly, grow up a lot, and the branches and leaves are dense. At this time, the small flowerpot can affect the continued growth of poinsettia, and the potted soil loses nutrients, resulting in yellowing of leaves.

Therefore, when cultivating poinsettia, we need to change the basin in time according to its growth status, and we need to loosen the soil frequently, so that nutrients and water can better nourish the roots and avoid soil consolidation.

The reason why poinsettia leaves turn yellow: the temperature is too low

When raising poinsettia, you need to pay attention to a temperature, because poinsettia likes a warm climate and is more afraid of cold. Plants are not as easy to freeze as expected, resulting in yellowing leaves. When raising poinsettia in winter, you need a higher temperature, between 15 ℃ and 18 ℃. Generally, it is relatively high in indoor culture. You need to pay attention to avoid cold wind and turn on heating if necessary.

The reason why poinsettia leaves turn yellow: too much watering

Poinsettia leaves yellowing, may be caused by too much watering, too much watering will lead to stagnant water in the basin. At this point, poinsettia roots will be lack of oxygen, and there may be rotten roots, which will cause the leaves to turn yellow. Therefore, in the cultivation of poinsettia, the need for reasonable watering, in the case of ensuring adequate water, to avoid stagnant water. If the phenomenon of rotten roots is found, the rotten roots should be cut off in time to avoid further infection.

The reason for the yellowing of poinsettia leaves: lack of light

Poinsettia can be said to be a short-day plant, but during the breeding period, it is best to maintain proper light, not to see the sun for a long time, so that it will lose green and turn yellow easily. Therefore, it is best to put poinsettia in a place with sufficient light for maintenance, which can promote its photosynthesis and is green in leaf color.

The reason why the leaves of poinsettia turn yellow, what if the leaves of poinsettias turn yellow?

Poinsettia as its name implies, of course, fiery red is the ornamental value of poinsettia, but sometimes farmers may not know much about the growth habits of poinsettia, resulting in the yellowing of poinsettia leaves due to improper maintenance. So what is the reason why the leaves of poinsettia turn yellow? Next, I would like to introduce to you what to do when the next magenta leaves turn yellow.

The reason for the yellowing of poinsettia leaves

The basic leaves of poinsettia are easy to turn yellow after the beginning of autumn, the main reasons are:

1. The basin soil is too dry

Because the weather is drier after autumn and the sun is still strong, it is easy to cause basin soil to dry. Therefore, the poinsettia placed on the balcony or in the sunny place should be fully watered in the morning and watered once in the evening.

2. The flowerpot is too small

At the beginning of planting, the flowerpot is smaller, after the growth of spring and summer, the plant becomes larger, the branches and leaves are more, and the leaves turn yellow due to the lack of nutrition in the basin soil. therefore, the pot should be changed in time after entering autumn. Poinsettia like warmth, afraid of cold, cold leaves are also easy to yellow in winter, raise poinsettia in winter should pay attention to cold. Poinsettia bought from the flower market, the road should be wrapped with newspapers to avoid blowing cold wind; domestic poinsettia, winter should be moved into the greenhouse, indoor temperature should be maintained 10 ℃-18 ℃, and pay attention to timely watering, so as to reduce leaf yellowing and shedding.

What if the leaves of poinsettia turn yellow?

Poinsettia needs plenty of light to grow well, only slightly shading during the summer high temperature to reduce the temperature of the small environment.

Watering should be dry and wet, and the topsoil should not be irrigated if it is not dry.

When whitefly is damaged, the leaves have small yellow spots, and then the whole leaves wither and fall off, so it is necessary to spray imidacloprid, lice aphid and other insecticides in time.

If the room temperature can be kept above 15 ℃ in winter, it can be truncated or coring while controlling diseases and insect pests, and beautiful bracts and inflorescences can be seen around Christmas.
