What if poinsettia does not blossom? the maintenance methods of poinsettia are different in spring, summer, autumn and winter.

In the flower world, the name of poinsettia is very loud. It blooms before and after Christmas, New Year's Day and Spring Festival. It is a very festive and colorful flower. However, in the breeding process, due to improper maintenance, poinsettia may not blossom, which poinsettia does not blossom? In fact, the key is maintenance, the following is the editor's selection of poinsettia four seasons maintenance method, very comprehensive, you must see if you love flowers.

What if poinsettia does not blossom

Earlier, we have introduced the efficacy and function of poinsettia, we know that it is not only ornamental, but also has a good medicinal value, but there is a major premise, that is, poinsettia to blossom. But for some reason, poinsettia may not blossom, so what if poinsettia does not blossom? In this regard, the editor sorted out several reasons, we can solve the problem, the specific reasons are as follows:

1. Lack of light for a long time

The failure of poinsettia to blossom may be caused by a long-term lack of light. Lack of light, poinsettia is not only not conducive to growth, but also easy to get sick, so red bracts can not be seen.

Solution: move your poinsettia to a sunny place quickly. I believe its red bracts will appear soon.

2. Insufficient fertilization

In the growing period, poinsettia needs a lot of nutrients, at this time, if the lack of fertilizer, it is fatal to the growth of poinsettia. Poinsettia, which is short of fertilizer, often has short and thin plants, and it is damned if the flowers can bloom.

Solution: hurry up to give it some special plant fertilizer, which is good for its germination and growth to eat red bracts. I believe that your poinsettia will blossom after careful care for a period of time.

3. Not yet in bloom

Poinsettia does not blossom. In addition to the above two main factors, there may be another reason, that is, the flowering time has not arrived. The flowering period of poinsettia can last from December to February of the following year. If its flowering time 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.

Second, the four-season maintenance method of poinsettia

To put it bluntly, if you want poinsettia to grow well and bloom beautifully, you need us to take good care of it. However, in the poinsettia culture methods and precautions, we have learned that poinsettia indoor farming requirements are many, and different throughout the year. In this regard, in order to facilitate flower friends, the editor sorted out the four seasons maintenance method of poinsettia, we might as well have a look.

1. Spring maintenance of poinsettia

Change the basin: April-May in spring is the best time to change the basin, when changing the basin soil choose fertile soil, good drainage soil. The quality of the soil directly affects the growth of poinsettia. When changing the soil, replace the soil of 1 stroke 3, so as not to adapt to the large-scale soil exchange plants.

Pruning: after changing the basin, it is necessary to ensure that the plant has sufficient water and light to promote the re-germination of its branches, the new semi-lignified branches can be cut off the cuttings, and the plant type can be pruned properly to make the old branches evenly distributed. If it is not pruned, the heart should be removed 2-3 times to ensure that the plant type is plump.

Watering: see dry and wet. Spring is the peak growing season for poinsettia. To ensure sufficient sunshine, it is also necessary to water it. To ensure that the basin soil is dry and wet, if too much watering, the basin soil is in a wet state for a long time, the root growth is poor, easy to rot the root. However, if the potted soil is dry for a long time, the root is easy to be withered, resulting in a lack of water. So if you want to water dry, you will water it, and if you see it wet, you will stop.

2. Summer maintenance of poinsettia

Light: avoid high temperature exposure. Poinsettia can not tolerate high temperature and hot sun, and the summer temperature should not exceed 28 ℃, otherwise it will grow badly. The plant should be grown in a semi-shady environment to ensure adequate water supply. When the temperature is high, it should be sprayed around it frequently, and ventilation should be strengthened to reduce the temperature. If the temperature is higher than 28 ℃ and the growth of poinsettia is stagnant, fertilization should be stopped and resumed when the temperature drops.

Watering and fertilization: it is hot and muggy in summer, but under normal circumstances, poinsettia still grows normally, replenish water in time and water once in the morning and evening to avoid watering in the hot sun. Apply rotten liquid fertilizer once every 20 days, apply fertilizer in the evening as far as possible, and bask in the sun the next morning.

3. Maintenance of poinsettia in autumn

Light: the temperature turns cool gradually in autumn, so it is necessary to gradually increase the light in the morning and evening to ensure an adequate supply of water and fertilizer. If the plant type has been formed, it can be treated with short-day light to promote flowering.

Temperature: when the temperature drops at the end of autumn, it is necessary to control the temperature, move the plant to indoor maintenance in time, and control the indoor temperature at about 20 ℃.

4. Poinsettia winter maintenance

Temperature: poinsettia is not cold-resistant, and flowering in early winter should be kept at 15 ℃ to ensure adequate light and water and fertilizer supply. Insufficient temperature affects flowering, at the same time, the leaves will appear yellowing and shedding, forming a foot loss, affecting the ornamental. In winter, all previous efforts have paid off, reducing the temperature appropriately when flowering, and the viewing period can be up to 2 months at 5-10 ℃.

What if poinsettia doesn't blossom?

What if poinsettia does not blossom? 1. Light leads to non-flowering

Poinsettia is a typical short-day plant. If you put poinsettia in an environment with light day and night, it will delay or fail to blossom. Especially at night, even if the poinsettia in the dark is exposed to the light for a short time, it will affect its frequent flowering.

How to deal with it?

Poinsettia is guaranteed to have about 13 hours of darkness every day at the right temperature. Especially at night, it is best to put black sunshade plastic bags or cloth on poinsettia plants and let them enter a completely dark environment so that they can blossom smoothly.

2. The temperature is too high and too low to cause it not to blossom.

Temperature will not only affect the flowering of poinsettia. If the ambient temperature is lower, for example, below 10 ℃, the flowering of poinsettia will be delayed and will not bloom as scheduled. If the ambient temperature is too high, for example, higher than 35 ℃, it will also affect the normal flowering of poinsettia.

How to deal with it?

In order to ensure the normal flowering of the plant, it is best to put the plant in an environment with a day temperature of 20 ℃-25 ℃ and a night temperature of 15 ℃. In this way, not only can poinsettia bloom normally, but also the beautiful bracts grow fat and symmetrically, and the ornamental value will increase accordingly.

The practice of blooming poinsettia 1. Give enough light

Poinsettia is a kind of short-day plant, if the sunshine time is too long, the leaves will not turn red. If you want to make the bracts of poinsettia turn red ahead of time, it is necessary to control the daily light within 12 hours. Only in this way can the flower buds differentiate.

If your poinsettia has not been red, you can try to light only 9 hours a day, so that the bracts will turn red after 5 weeks.

Poinsettia is not yet in bloom

Poinsettia florescence in December-February of the next year, if its flowering has not yet arrived, in the stem and leaf growth period, green leaves will continue to sprout, flower friends will naturally see less red bracts.

It is suggested that flower friends should give enough sunshine to poinsettia to promote the rapid growth of stems and leaves, and only after luxuriant branches and leaves can the bracts turn red.

3. Give enough fertilizer, especially those containing potassium and phosphorus

Do not pay attention to fertilization, too much nitrogen fertilizer, lack of phosphorus and potassium will cause poinsettia bracts impure color. In the growing and flowering season, liquid fertilizer is applied every half a month or so. After autumn, more fertilizers rich in potassium and phosphorus should be applied to promote flower bud differentiation and ensure the purity of bract leaves.

Postpone the flowering of poinsettia

The flower buds of poinsettia during flowering are sensitive to light and difficult to differentiate in a light environment. As long as the plant is exposed to more light, the flowering period can be delayed. Flower friends maintain normally during the day, and can be brightened from 10:00 in the evening to 2 o'clock in the morning. Generally, the candlelight intensity of about 100 meters around poinsettia can prevent flower bud differentiation, and small night lights can be used at home. Similarly, the temperature should not exceed 23 ℃. Of course, different varieties have different perception of light. It is appropriate to add light treatment in September.

Let poinsettia blossom ahead of time

Three weeks after picking the heart of a poinsettia, the plant was covered with a piece of black cloth after shading at a temperature of 20 ℃ and 25 min. It was given 9 hours of light every day, that is, it was shaded by a dark curtain at 5 pm and opened at 7-8 pm the next day. The single variety 45mi could blossom in 55 days, and the double variety 55Mel could bloom in 65 days. Such as shading treatment from the first ten days of August, ventilation and cooling at night, topdressing once a week, the parietal leaves begin to change color in late September, and can be watched on National Day.

What if poinsettia doesn't blossom?

The natural flowering period of poinsettia is around New Year's Day. However, many flower growers find that poinsettias do not blossom in spring, so they are unable to appreciate their beautiful bracts. In this case, the following measures can be taken to make it blossom. Poinsettia is a typical short-day plant. In order for it to blossom, it must avoid the light at night behind its house and put it in roughly the same place as the diurnal variation of nature. If you do not pay attention to this problem, it will cause the florescence of a poinsettia to be delayed or fail to bloom. It should be noted that even if poinsettia in the dark is exposed to light for a short time at night, it will affect its frequent flowering. So put it in a completely dark place. Temperature discomfort can affect the flowering of poinsettia. If the ambient temperature is lower, for example, below 10 ℃, the flowering of poinsettia will be delayed and will not bloom as scheduled. If the ambient temperature is too high, for example, higher than 35 ℃, it will also affect the normal flowering of poinsettia. The cultivation practice shows that in order to ensure the normal flowering of the plant, it is best to put the plant in an environment with a daily temperature of 20 ℃ and a night temperature of 15 ℃. In this way, not only can poinsettia bloom normally, but also the beautiful bracts grow fat and symmetrically, and the ornamental value will increase accordingly. .
