How to care for orchids in winter? Frost protection is key

Potted orchids at home stop growing in winter, but how well they are managed during this period directly affects how well they grow the following year. Otherwise, they are prone to freezing to death, frost damage, empty roots and black spot disease, and in severe cases, death. Gardening experts remind that every orchid grower must pay attention to winter care for orchids, especially the watering method for orchids, which involves a great deal of knowledge.

　　

Experts say that when caring for orchids, you must grasp the correct time to move them indoors, spray disease- and pest-prevention chemicals before moving them indoors, pay attention to frost protection, ventilate regularly, and prevent the potting soil from becoming too dry or too wet. Generally speaking, orchids stop growing in winter and their water demand decreases. Orchids have fleshy roots, and generally withholding water can keep them alive, but if the potting soil stays dry for a long time, healthy orchid roots will become empty roots, and this will not be reflected on the orchid leaves for a while. By the time it shows on the orchid leaves, the orchid roots have already suffered severe damage, and in serious cases they have already dried up and died. The correct way to water orchids is "do not water if not dry" and "if you water, water thoroughly." Orchid pots that are too dry can be soaked in water until thoroughly wet.
