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.
