Winter Management of Orchids
In winter, strengthening the management of orchids is the key to the growth and blooming of orchids in the coming year. The ancients' experience of raising orchids was "three-point planting and seven-point planting." How to manage orchids in winter, according to different varieties of orchids, take different management methods. According to my experience in raising orchids for many years, to ensure safe wintering of orchids, we must strengthen the management of water, fertilizer, temperature and air. Moisture: "Summer and autumn can not be dry, winter and spring is not wet" principle. This is the valuable experience that our predecessors have summed up for us to cultivate a good orchid. According to the morphological structure of orchids, they are a kind of mesophytic plants that are not easy to die. They do not need a lot of water. In winter, orchids go into dormancy and no longer grow. (Excluding spring, cold, and Muran) Natural water and snowy water are preferred for water, and cannot be poured directly with tap water. (Use tap water to store water for 24 hours.) When watering, it should be poured into the pot around the flowerpot so that it gradually penetrates into the flower root and avoid injecting into the leaves and orchids. Fertilizers: According to the characteristics of orchid roots, orchid roots do not have fibrous roots, and roots have symbiotic bacteria. In general, if orchids change pots every year, and the soil contains enough nutrients, it is absolutely unnecessary to fertilize them. Even if the 2-3 years of potting change, they do not grow in the dormant period in winter, they do not need to fertilize. If the fertilizer is applied in winter, the orchid roots will turn black and even rot (except for spring and cold blue in the growth period). Temperature: In the winter, affected by the northern cold current, the temperature is relatively low, and orchids placed outdoors should be moved indoors or in closed balconies. It is best to place the blue pot facing south to prevent direct intrusion of cold currents. This orientation can be exposed to the sun in the morning, avoiding the sun's rays and favoring the growth of orchids. Air: Orchids, like other plants, need air circulation. Orchids placed indoors should always be moved to the balcony or outdoors (preferably around noon) so that it can absorb fresh air, see the sun, and put it in a closed balcony. Always open the window door to allow air to circulate, and close it in the evening to prevent cold air intrusion at night.
