How to manage orchids in winter? Management methods of Orchid in Winter

In winter, strengthening the management of orchids is the key to the growth and flowering of orchids in the coming year.

The experience of the ancients in raising orchids was divided into three parts and seven points. How to manage orchids well in winter, we should adopt different management methods according to different varieties of orchids. According to the experience of raising orchids for many years, in order to make orchids survive the winter safely, it is necessary to strengthen the management of moisture, fertilizer, temperature and air.

Moisture: summer and autumn can not be dry, winter and spring can not be wet this is the predecessors summed up for us the experience of growing orchids. According to the morphological structure of orchids, they are mesophytic plants, which are not easy to dry and die, and do not need a lot of water. Orchids enter a dormant period in winter, no longer grow, and can be watered once a week. (except spring, cold, ink orchid) natural water is the best, snowmelt water is the best, and tap water can not be used directly. (tap water should be put in an accumulator for 24 hours) when watering, it should be poured around the flowerpot to make it gradually penetrate into the flower root, and do not inject it into the leaf and orchid heart.

Fertilizer: according to the characteristics of orchid root, the orchid root is thick and long without whisker root, and there is symbiosis of root fungi in the root. Generally speaking, if orchids change pots and soil every year, and the soil contains enough nutrients, there is no need to apply fertilizer at all. Even if they change pots for 2-3 years, they no longer grow during the dormant period in winter, let alone need fertilizer. If fertilized in winter, the orchid root will turn black and even rot. (except for spring and cold orchids in the growing period) temperature: in winter, affected by the cold spell in the north, the temperature is relatively low. Orchids placed outdoors should be moved indoors or balconies with aluminum alloy devices. Orchid pots are best placed in the direction of north to south, which can prevent the direct invasion of cold current. This orientation can be exposed to the sun in the morning to avoid the setting sun, which is beneficial to the growth of orchids. Air: orchids, like other plants, need to be ventilated. Orchids placed indoors should often be moved to the balcony or outdoors (preferably around noon) so that they can absorb fresh air, see the sun and put them in the balcony with aluminum alloy installations. always open the window to make the air circulate.
