What is the cultivation method of poinsettia?
Today, the editor will introduce the cultivation method of poinsettia and some basic knowledge of growing flowers, including the techniques for cultivating poinsettia. Let's dive into the comprehensive introduction.
Cultivate "poinsettia" in October, focus on several key maintenance tasks for vibrant and festive blooms
After entering October, poinsettias begin to bloom one after another. The bright red flowers and leaves are particularly striking in the golden autumn season, very beautiful and festive, making them ideal for decorating flower beds or placing them in pots in the sun for enjoyment.
For poinsettia potted plants at home, proper watering, fertilizing, and lighting maintenance during the autumn period will quickly lead to blooming, and the top leaves will turn red and festive.
Keep the potting soil slightly moist
Poinsettia does not tolerate drought and is afraid of waterlogging. In autumn, which is its vigorous growth period, watering should be done reasonably. Do not let the potting soil become too dry or water it too frequently. Dry soil can slow down the growth of the plant's branches and leaves, while overly moist or waterlogged pots can easily cause root rot and yellow leaves. Therefore, water the plant when the surface of the potting soil is dry to keep the soil slightly moist, allowing the plant to grow vigorously and bloom soon.
Apply phosphorus and potassium fertilizers
Poinsettia starts to grow branches and leaves rapidly in the early autumn, which is a period of nutritional growth. You can water it with well-fermented cake fertilizer or other nutrient solutions every half a month to promote vigorous growth.
After entering October, many well-maintained plants are about to bloom. At this time, reduce the use of nitrogen fertilizers and switch to high-phosphorus and high-potassium fertilizers to promote blooming. Many flower enthusiasts don't understand what phosphorus and potassium fertilizers are; they are fertilizers with a high content of phosphorus and potassium elements, such as commonly used phosphorus and potassium fertilizers like monopotassium phosphate and Huaduo No. 2, which can all be used.

Ensure adequate lighting
Poinsettia is a short-day plant. In summer, it should be moved to a cool and ventilated place for maintenance and provided with shade to prevent the leaves from being sunburned by strong sunlight.
After entering autumn, the plant starts to grow rapidly, and it's time to increase lighting, allowing it to receive more scattered light, which will promote more vigorous growth. In deep autumn and winter, you can let it get more direct sunlight to promote blooming.
Move indoors before cooling down
Poinsettias maintained outdoors should be moved to a warm environment before the frost. They are not cold-tolerant and will stop growing when the temperature drops below 10°C. In winter, place the potted plants in a warm place where sunlight can reach, so even in winter, blooming is not affected.
Prune promptly after flowering
Around Qingming Festival in spring, the blooming period of poinsettia is basically over. At this time, start pruning and shaping the plant, cutting off the withered flowers and yellow leaves. After pruning, supplement the nutrients, and the plant will grow new branches and leaves, allowing it to bloom again.
When growing poinsettia at home, also be aware that the white sap contains certain toxic components, which can cause discomfort when it comes into contact with the skin. If you have children at home, try to place it out of their reach.
