What if a poinsettia loses its leaves? there are 6 reasons and 6 treatment methods.

What about the leaves of poinsettia? 1. The strong light causes the leaves to fall.

Poinsettia should not be exposed to strong light in summer. If the sun is too strong and the ventilation is not good, it is easy to lose the leaves of poinsettia due to high temperature drying.

Treatment method

In summer, poinsettia plants should be placed in a well-ventilated place to prevent sunlight exposure, make certain shading measures, keep a distance of 50 centimeters between pots, and spray water frequently on the ground to increase air humidity.

2. The low ambient temperature causes the leaves to fall.

Poinsettia prefers warm, humid, cool climate, not cold-resistant, suitable for growth of 15 ℃ 20 ℃, winter night to maintain more than 15 ℃, not less than 5 ℃, otherwise poinsettia leaves fall off. Opening a window and blowing a cold wind in winter can also lead to a large number of fallen leaves of poinsettia.

Treatment method

Poinsettia in winter should raise the temperature in mid-October and keep the plants in a relatively stable indoor environment. By the middle of October, it should be placed in a warm place facing south to the sun to ensure that it will not be hit by the cold wind and cause fallen leaves.

3. Overwatering stagnant water, causing leaves to fall.

Poinsettia is afraid of dryness and waterlogging, the basin soil is too wet, the photosynthesis of poinsettia can not be carried out well, resulting in poinsettia malnutrition and fallen leaves.

Treatment method

If too much watering causes leaf loss recently, poinsettias need to be placed in a cool, ventilated place, given enough light during the day to dry the excess moisture in the soil, and then return to normal watering. In addition, it is necessary to drain water in case of heavy rain, or move poinsettia indoors before the rain.

4. Too little watering causes the leaves to fall.

Poinsettia likes to be wet, if the pot soil is too dry, it will make poinsettia physiologically short of water, causing poinsettia leaves to curl and a large number of fallen leaves.

Treatment method

Grasp the frequency and quantity of watering poinsettia. Generally speaking, poinsettia is watered every 2 days in spring. When branches and leaves are luxuriant and growing fast in summer, the amount of water should be large and sufficient water should be provided. In winter, watering needs to be controlled, and watering should be reduced after flowering.

5. Improper fertilization leads to leaf drop.

Poinsettia likes fertilizer, more nitrogen fertilizer is needed in the growing period, and insufficient nitrogen fertilizer will make the lower leaves of poinsettia fall off.

Treatment method

In addition to the base fertilizer used in the basin, in the month after picking the heart, apply mellow thin pancake fertilizer and water every 7 days or so, not too much. Do not fertilize during flowering, otherwise the leaf bud will be anxious. Before entering the house in winter, apply a small amount of compound fertilizer to help it through the winter. Be careful not to fertilize too much so as not to burn roots.

6. Moisture and humidity cause leaves to fall

Poinsettia is more sensitive to water. If flower friends water poinsettia for a while and do not remember to water, the pot soil is too dry, it will easily cause a large number of poinsettia leaves to fall off.

Treatment method

Poinsettia is not resistant to drought and moisture. Watering should be flexibly mastered according to the weather, basin soil and plant growth. Generally, it is better to keep the basin soil moist without stagnant water.

What if a poinsettia loses its leaves? what if a poinsettia flower is not red?

Poinsettia belongs to both flowering plants and foliage plants. Today, the editor will tell you about how poinsettias lose their leaves and how poinsettias lose their leaves.

Reason 1: excessive light

If poinsettia is exposed to the hot sun for a long time, its leaves may fall off due to dryness, which is most common in summer.

Solution: put poinsettia indoors in a season of intense sunshine and water more according to room temperature, or increase the humidity of the indoor air, so that the leaves do not fall off easily.

Reason 2: too low temperature

Poinsettia is not hardy and should not grow at room temperature too low. If the room temperature is less than 5 ℃, the leaves are easy to fall off.

Solution: in the cold winter, it is best to put poinsettia in a place with higher temperature to cultivate. If such a place can not be found, it is recommended to turn on the heat to adjust the indoor temperature.

Reason 3: too much watering

Poinsettia is afraid of waterlogging, too much watering, basin soil is too wet, poor photosynthesis, leaves are easy to fall off because of lack of nutrition.

Solution: poinsettia should be watered properly, try not to water too much, and do a good job of drainage on rainy days.

Reason 4: too little watering

Poinsettia lack of water, the leaves will curl, or even a large number of fall off, if you find this situation, you should pay attention to watering.

Solution: poinsettia is watered every 2 days in spring. When the branches and leaves are luxuriant and growing fast in summer, the amount of water should be large and sufficient water should be provided.

Reason 5: improper fertilization

Poinsettia likes fertilizer, needs more nitrogen fertilizer in the growing period, and the lack of nitrogen fertilizer will make the lower leaves of the plant fall off.

Solution: do not apply too much fertilizer, especially at the flowering stage, otherwise the leaves are anxious due to excessive nutrition. in addition, in winter, fermented human feces and urine are recommended.

What if poinsettia flowers are not red?

Here are several possible causes and solutions:

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 short of fertilizer tend to be short and thin. Is the editor right? Hurry up to give it some special plant nutrition fertilizer, which is good for its germination and growth to eat red bracts.

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.
