Dendrobium orchid is a beautiful and elegant ornamental flower with small and delicate flowers and rich colors. However, in the process of cultivation, Dendrobium orchid is prone to root rot, and this paper will analyze the causes of root rot in Dendrobium orchid.
First, improper watering is the main cause of root rot in Dendrobium orchid. The root system of Dendrobium orchid has a high demand for water, but excessive water can easily lead to hypoxia in the root of Dendrobium orchid, and then the phenomenon of root rot occurs. Therefore, when watering Dendrobium orchid, you should control the humidity, not accumulate water, and ensure that the soil is moist. In addition, it is also necessary to pay attention to the water temperature when watering to avoid too much difference between the water temperature and the soil temperature, which will affect the growth of the root system of Dendrobium orchid.
Second, improper fertilization is also an important factor causing root rot of Dendrobium orchid. Dendrobium orchid needs sufficient nutrients during the growth process, but too much fertilizer will affect the root respiration of Dendrobium orchid, which in turn will lead to root rot. Therefore, in the process of fertilizing Dendrobium orchid, an appropriate and balanced fertilizer should be selected, and the principle of "thin fertilizer and frequent application" should be followed.
Third, Dendrobium orchid is not suitable for the growth environment. Dendrobium orchids need a warm, moist, half-shade and half-yang environment to grow. If the Dendrobium orchid is placed in direct sunlight or in an excessively shady place, it will cause the temperature of the root of the Dendrobium orchid to be too high or too low, affecting the normal growth, which will lead to the root rot of the Dendrobium orchid.
Fourth, the soil is not suitable. The root system of Dendrobium orchid has relatively high soil requirements and needs loose, breathable and well-drained soil. If the soil is not suitable, it will lead to water accumulation and hypoxia in the roots of Dendrobium orchid, which in turn will cause root rot of Dendrobium orchid. Therefore, when cultivating dendrobium orchids, it is necessary to choose the soil suitable for its growth.
In short, to avoid root rot of Dendrobium orchid, it is necessary to take the correct maintenance method. Only in this way can the dendrobium orchid thrive and bloom into beautiful flowers. Add a touch of greenery and poetry to our lives.
