Does the poinsettia fear sun exposure?
Today, the editor will explain whether the poinsettia fears sun exposure and knowledge about the green plant and flower cultivation techniques related to poinsettias. Let's learn about it together below.
Chinese people attach great importance to the Spring Festival. They work hard and busy during the entire month of December to select New Year's flowers, hoping to have a lively and auspicious atmosphere during the New Year's days. Today, let me introduce a kind of poinsettia that can bloom in the winter with fiery red flowers.
The poinsettia has been very popular in recent years as a New Year's flower. It has a beautiful and elegant plant. When it blooms, the oil-green leaves are complemented by the fiery red flowers, making it look very festive. Especially during the New Year, the bright red flowers blooming at home look incredibly beautiful! Next, let's talk about the precautions for caring for poinsettias!
1. Take good insulation measures
The most important thing in caring for plants in winter is to take good insulation measures. Poinsettias prefer a warm living environment and have poor cold resistance, suitable for growing in temperatures of 15-20 degrees Celsius. If the indoor temperature in winter does not meet this, not only will you not see poinsettias bloom, but the plant is also very prone to frostbite. Therefore, northern gardeners should move it indoors for care at the end of autumn. If the indoor temperature in winter cannot reach 15 degrees, you can also cover the poinsettia plant with a layer of plastic bag for insulation!
2. Ensure adequate sunlight
Poinsettias love to bask in the sun and require ample sunlight throughout the year. Therefore, in winter, it is even more important to place it in a sunny south-facing balcony or windowsill for care. Otherwise, if the poinsettia does not receive sufficient sunlight, it is very prone to leaf shedding, few flowers, and dull flower color, which greatly reduces its ornamental value and is not conducive to the plant's growth.
3. Reduce watering appropriately
Poinsettias are strict with water requirements. The soil should neither be too dry nor too wet. Therefore, we must control the amount of watering, especially in winter, when the temperature is relatively low and the evaporation of water is naturally slower. We must control the amount of watering, and only water when the potting soil is not dry. Also, water the plant with water close to room temperature on sunny midday, as it is very easy to stimulate the poinsettia's roots, causing root damage.

Additionally, when watering the poinsettia, we must avoid its flower buds and flowers. If water droplets fall on them, it can easily lead to blackened flower buds and their falling off. Poinsettias also like humid environments. If there is air conditioning and heating at home, the indoor environment may be quite dry. We should also frequently spray the plant with room temperature water to keep it moist, and those with conditions can also place a humidifier around the plant for better results!
4. Fertilize appropriately
Poinsettias consume a lot of nutrients when blooming, so regular fertilization must keep up. Apply 2-3 times of nutrient-rich compound fertilizer per month to provide the plant with ample nutrients, which naturally leads to more and better flowers. Before the blooming period, apply phosphorus and potassium fertilizer every 10 days to help the poinsettia differentiate more flower buds and flower buds. However, be sure to control the amount of each application and never apply heavy fertilizer.
But after entering winter, if the indoor temperature cannot be maintained above 15 degrees, the plant will enter a dormant period, and the root system's ability to absorb nutrients will weaken. We should also stop all forms of fertilization in time, as otherwise, it could increase the burden on the roots, causing fertilizer damage and harming the plant's health.
If you want the poinsettia to bloom fiery red during the New Year, you must keep the indoor temperature above 15 degrees and then carry out reasonable care based on the indoor temperature!
