Poinsettias, also known as Euphorbia pulcherrima or Christmas flowers, have beautiful branches and leaves, with bright colors, making them excellent ornamental plants. Moreover, they have a long flowering period and can be seen in many places such as parks, botanical gardens, and so on. So, can poinsettias be grown indoors? Let's find out.
If you simply want to grow poinsettias indoors for ornamental purposes or to beautify the environment, then there is absolutely no problem. However, as a member of the Euphorbiaceae family, they also contain toxins such as alkaloids, which are harmful to humans. Additionally, their bright colors can easily attract babies or pets to ingest them accidentally, leading to poisoning. Therefore, extra caution is necessary. Furthermore, it is advisable to wear gloves when pruning, and after pruning, hands or any skin exposed to the sap should be washed thoroughly with soapy water.
How to Grow Poinsettias Indoors?
-
Soil Selection: It is best to use fertile and well-drained soil for poinsettias. A mixture of garden soil, humus, leaf mold, and cake manure in a ratio of 3:3:3:1 is commonly used for preparing nutrient-rich soil.
-
Temperature and Light: Poinsettias prefer warmth and are sensitive to cold. The optimal temperature for their growth is between 18-25°C, and in winter, it should not drop below 10°C. Additionally, they require short daylight hours and strong light, needing 8-9 hours of light daily.
-
Watering: Poinsettias have low water requirements; keeping the soil slightly moist is sufficient. Watering should be moderate, avoiding waterlogging or allowing the soil to dry out. In spring and autumn, watering every 1-2 days is sufficient; in summer, watering once in the morning and evening is recommended, while in winter, watering every 3-4 days is adequate.
-
Fertilization: During the growth and flowering season, it is recommended to fertilize with diluted sesame residue liquid fertilizer every 10 to 15 days. In autumn, a 0.3% compound fertilizer can be applied weekly for 3 to 4 times to promote bract coloration and flower bud differentiation.
-
Pruning: Poinsettias grow rapidly and require regular pruning. When pruning, prune the old branches vigorously, leaving only 2-3 buds at the base of each branch, and remove all other branches. Pay attention to pinching, leaving 5-9 flower heads and cutting off the others promptly after flowering to avoid nutrient waste.
Overall, poinsettias can be grown indoors, but precautions must be taken to avoid ingestion. Proper techniques and methods are also essential for their cultivation, ensuring that the flowers of poinsettias are bright and beautiful, adding a festive atmosphere.
