What are the cultivation methods for Poinsettia in summer?
Let me tell you about the cultivation methods for Poinsettia in summer and the precautions for maintaining Poinsettia in terms of green plants. Next is a comprehensive introduction.
Keep four maintenance points in mind when growing a pot of Poinsettia, and you will get plenty of bright red flowers, which is truly joyous.
Poinsettia is a flower with particularly beautiful and festive blooms. In the autumn and winter flowering season, its top leaves turn deep red, making it very beautiful and attractive. So, how should we maintain it to ensure that the Poinsettia grows vigorously and blooms with a sea of red flowers during the flowering season?
One, pay attention to shading in the summer
Poinsettia is a short-day flowering plant. During the vigorous growth periods of spring and autumn, it can be placed in a sunny location to get more sunlight. However, the summer sun is too strong, and direct exposure can easily burn its leaves. It's best to use a shading net for sun protection or move the potted plant to a place with weak scattered light. As the autumn sun becomes less intense, gradually increase the light exposure to encourage early flowering.
Two, watering requirements
In spring and autumn, which are the vigorous growth periods for Poinsettia, the potting soil should not be too dry or lack water, preferably keeping it slightly moist but not waterlogged. In the hot summer, water evaporates quickly, and the watering should be done when the soil feels dry to the touch. Do not water too frequently, as overly moist soil can lead to root rot and yellow leaves. If too much water is accidentally poured, and the plant's leaves turn yellow, move the pot to a well-ventilated area and frequently loosen the soil to increase soil permeability and prevent root rot.
Although watering should not be too frequent during high temperatures, sprinkling water on the plant can increase the humidity of the environment and prevent the leaves from drying out.
Three, how to fertilize?
Poinsettia enjoys fertilizer. In the absence of nutrients, the plant will become weak and the growth of branches and leaves will decrease. Therefore, it is necessary to fertilize regularly during the growing period to supplement nutrients. For example, apply a thin fertilizer once or twice a month, such as a small amount of NPK compound fertilizer in the pot, which can promote vigorous growth of the plant.
Four, pruning and pinching
In the spring, when the Poinsettia is growing vigorously, pinch the top to encourage more branching and increase the number of flowers. Regular pruning and shaping are also necessary to remove withered and diseased branches and leaves, increasing ventilation and light penetration between the plants. After entering autumn, avoid extensive pruning to prevent cutting off branches that are about to bloom. After the flowering season, prune the spent flowers and supplement nutrients.
Many flower friends find that their Poinsettia leaves turn yellow and fall off in the summer. When maintaining the plant, it is important to enhance ventilation, avoid frequent watering, and ensure proper shading and sun protection. After October, supplement phosphorus and potassium fertilizers, and the plant will soon bloom in large numbers, with bright red flowers that look very festive and beautiful.
